1.5 Acronis Backup components
This section contains a list of Acronis Backup components with a brief description of their
functionality.
Components for a managed machine (agents)
These are applications that perform data backup, recovery and other operations on the machines
managed with Acronis Backup. Agents require a license to perform operations on each managed
machine.
Console
The console provides Graphical User Interface to the agents. Usage of the console is not licensed. The
console is installed together with the agent and cannot be disconnected from it.
Bootable Media Builder
With Bootable Media Builder, you can create bootable media in order to use the agents and other
rescue utilities in a rescue environment. Bootable Media Builder is installed together with the agent.
1.5.1 Agent for Windows
This agent enables disk-level and file-level data protection under Windows.
Disk backup
Disk-level data protection is based on backing up either a disk or a volume file system as a whole,
along with all the information necessary for the operating system to boot; or all the disk sectors using
the sector-by-sector approach (raw mode). A backup that contains a copy of a disk or a volume in a
packaged form is called a disk (volume) backup or a disk (volume) image. It is possible to recover
disks or volumes as a whole from such backup, as well as individual folders or files.
File-level data protection is based on backing up files and folders residing on the machine where the
agent is installed or on a network share. Files can be recovered to their original location or to another
place. It is possible to recover all files and folders that were backed up or select which of them to
recover.
Other operations
Conversion to a virtual machine
Agent for Windows performs the conversion by recovering a disk backup to a new virtual machine of
any of the following types: VMware Workstation, Microsoft Virtual PC, Citrix XenServer Open Virtual
Appliance (OVA) or Red Hat Kernel-based Virtual Machine (KVM). Files of the fully configured and
operational machine will be placed in the folder you select. You can start the machine using the
respective virtualization software or prepare the machine files for further usage.
Recovery to dissimilar hardware
You can use the restore to dissimilar hardware functionality on the machine where the agent is
installed and create bootable media with this functionality. Acronis Universal Restore handles
differences in devices that are critical for the operating system start-up, such as storage controllers,
motherboard or chipset.
Disk management
Agent for Windows includes Acronis Disk Director Lite - a handy disk management utility. Disk
management operations, such as cloning disks; converting disks; creating, formatting and deleting
volumes; changing a disk partitioning style between MBR and GPT or changing a disk label, can be
performed either in the operating system or using bootable media.
1.5.2 Management Console
Acronis Backup Management Console is an administrative tool for local access to Acronis Backup
agent. Remote connection to the agent is not possible.
1.5.3 Bootable Media Builder
Acronis Bootable Media Builder is a dedicated tool for creating bootable media (p. 239). The media
builder that installs on Windows can create bootable media based on either Windows Preinstallation
Environment, or Linux kernel.
1.6 About using the product in the trial mode

1. Select Tools > Create bootable media in the menu.
2. Click Next in the welcome screen. Keep clicking Next until the list of components appears.
3. Proceed as described in "Linux-based bootable media" (p. 169).
Step 1. Installation
These brief installation instructions enable you to start using the product quickly. For the
complete description of installation methods and procedures, please refer to the Installation
documentation.
Before installation, make sure that:
Your hardware meets the system requirements.
You have a license key for the product of your choice.
You have the setup program. You can download it from the Acronis website.
To install Acronis Backup
Run the Acronis Backup setup program and follow the on-screen instructions.
Step 2. Running
Run Acronis Backup by selecting Acronis Backup from the Start menu.
For understanding of the GUI elements see "Using the management console" (p. 13).
Step 3. Bootable media
To be able to recover an operating system that fails to start, or deploy it on bare metal, create
bootable media.
Step 4. Backup
Back up now (p. 34)
Click Back up now to do a one-time backup in a few simple steps. The backup process will
start immediately after you perform the required steps.
To save your machine to a file:
Under Where to back up, click Location, and select the location where the backup will be
saved. Click OK to confirm your selection. Click OK at the bottom of the window to start the
backup.
Tip. Using the bootable media, you can do off-line ("cold") backups in the same way as in the
operating system.
Create backup plan (p. 34)
Create a backup plan if you need a long-term backup strategy including backup schemes,
schedules and conditions, timely deleting of backups, or moving them to different locations.
To recover data, you need to select the backed-up data and the destination the data will be
recovered to. As a result, a recovery task will be created.
Recovery of a disk or volume over a volume locked by the operating system requires a
reboot. After the recovery is completed, the recovered operating system goes online
automatically.
If the machine fails to boot or if you need to recover a system to bare metal, boot the
machine using the bootable media and configure the recovery operation in the same way as
the recovery task.
Step 6. Management
The Navigation pane (at the left part of the console) enables you to navigate across the product
views that are used for different administering purposes.
Use the Backup plans and tasks view to manage backup plans and tasks: run, edit, stop and
delete plans and tasks, view their states and progress.
Use the Alerts view to rapidly identify and solve the problems.
Use the Log view to browse the operations log.
The location where you store backup archives is called a vault (p. 249). Navigate to the
Vaults (p. 144) view to obtain information about your vaults. Navigate further to the specific
vault to view backups and their contents. You can also select the data to recover and perform
manual operations with backups (mounting, validating, deleting).

2.1.2 Main area, views and action pages
The main area is a basic place where you work with the console. Here you create, edit and manage
backup plans, recovery tasks and perform other operations. The main area displays different views
and action pages according the items you select in the menu, or Navigation tree.
Click a column's header to sort items in ascending order.
Click it once again to sort items in descending order.
A view appears on the main area when clicking any item in the Navigation tree in the Navigation
pane (p. 14).
"Log" view
Common way of working with views
Generally, every view contains a table of items, a table toolbar with buttons, and the Information
panel.
Use filtering and sorting (p. 16) capabilities to search the table for the item in question.
In the table, select the desired item.
In the information panel (collapsed by default), view the item's details. To expand the panel, click
the arrow mark ().
Perform actions on the selected item. There are several ways of performing the same action on
selected items:
By clicking the buttons on the table toolbar.
By selecting the items in the Actions menu.
By right-clicking the item and selecting the operation in the context menu.
Sorting, filtering and configuring table items
The following is a guideline to sort, filter and configure table items in any view.
In a field below the corresponding column's header, select the required value
from the drop-down list.
Filter items by entered value
In a field below the corresponding column's header, type a value.
As a result you will see the list of values, fully or just partly coincide with the
entered value.

This section attempts to give its readers a clear understanding of the product so that they can use
the product in various circumstances without step-by-step instructions.
3.1 Owners
This section explains the concept of a backup plan (task) owner and an archive owner.
Plan (task) owner
A local backup plan owner is the user who created or last modified the plan.
Tasks, belonging to a backup plan, are owned by the backup plan owner.
Tasks that do not belong to a backup plan, such as the recovery task, are owned by the user who has
created or last modified the task.
Managing a plan (task) owned by another user
Having Administrator privileges on the machine, a user can modify tasks and local backup plans
owned by any user registered in the operating system.
When a user opens a plan or task for editing, which is owned by another user, all passwords set in
the task are cleared. This prevents the "modify settings, leave passwords" trick. The program displays
a warning each time you are trying to edit a plan (task) last modified by another user. On seeing the
warning, you have two options:
Click Cancel and create your own plan or task. The original task will remain intact.
Continue editing. You will have to enter all credentials required for the plan or task execution.
Archive owner
An archive owner is the user who saved the archive to the destination. To be more precise, this is the
user whose account was specified when creating the backup plan in the Where to back up step. By
default, the plan's credentials are used.
3.2 Credentials used in backup plans and tasks
This section explains the concept of access credentials, backup plan's credentials and task
credentials.
Access credentials
When browsing backup locations, setting up backups, or creating recovery tasks, you may need to
provide credentials for accessing various resources, such as the data you are going to back up or the
location where the backups are (or will be) stored.
If the Credentials cache (p. 18) option is enabled (it is enabled by default), the credentials which you
provide during a console session are saved for use during the later sessions. Thus, there is no need to
enter the credentials next time. The credentials are cached independently for each user who uses the
console on the machine.
Any backup plan running on a machine runs on behalf of a user.
In Windows
By default, the plan runs under the agent service account, if created by a user having administrative
privileges on the machine. If created by a regular user, such as a member of the Users group, the
plan runs under this user's account.
When creating a backup plan, you are only asked for credentials in specific cases. For example:
You are scheduling backups as a regular user and did not enter credentials when connecting the
console to the machine. This may be the case when the console is installed on the same machine
that you are backing up.
You are backing up a Microsoft Exchange cluster to a storage node.
Specifying the credentials explicitly
You have the option to explicitly specify a user account under which the backup plan will run. To do
this, on the backup plan creation page:
1. In the Plan parameters section, click Show plan's credentials, comments, label.
2. Click Plan's credentials.
3. Enter the credentials under which the plan will run. When entering the name of an Active
Directory user account, be sure to also specify the domain name (DOMAIN\Username or
Username@domain).
In Linux
You do not need to specify backup plan's credentials. In Linux, backup plans always run under the
root user account.
Task credentials
Like a backup plan, any task runs on behalf of a user.
In Windows
When creating a task, you have the option to explicitly specify an account under which the task will
run. Your choice depends on whether the task is intended for manual start or for executing on
schedule.
Manual start
Every time you manually start the task, the task will run under the credentials with which you are
currently logged on. Any person that has administrative privileges on the machine can also start
the task. The task will run under this person's credentials.
The task will always run under the same credentials, regardless of the user who actually starts
the task, if you specify the task credentials explicitly.
Scheduled or postponed start
The task credentials are mandatory. You cannot complete the task creation until you specify the
task credentials. Task credentials are specified on the task creation page in a similar manner as
the plan’s credentials are specified.
In Linux
You do not need to specify task credentials. In Linux, tasks always run under the root user account.
When managing a machine running Windows, the scope of a user's management rights depends on
the user's privileges on the machine.
Regular users
A regular user, such as a member of the Users group, has the following management rights:
Perform file-level backup and recovery of the files that the user has permissions to access—but
without using a file-level backup snapshot (p. 90).
Create backup plans and tasks and manage them.
View—but not manage—backup plans and tasks created by other users.
View the local event log.
Backup operators
A user who is a member of the Backup Operators group, also has the following management right:
Back up and recover the entire machine or any data on the machine, with or without using a disk
snapshot. Using a hardware snapshot provider may still require administrative privileges.
Administrators
A user who is a member of the Administrators group, also has the following management right:
View and manage backup plans and tasks owned by any user on the machine.
3.4 List of Acronis services
During installation, Acronis Backup creates several services. Some of these services can be used by
other Acronis products installed on the machine.
Services of Acronis Backup
The services include the main service and a number of auxiliary services.
The main service can run under a dedicated account or under an account you specify during
installation. Either of the accounts is given privileges that are needed for the service to work. The
privileges include a set of user rights, membership in security groups, and the Full Control
permissions on registry keys in the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Acronis. There
are no permissions granted on other registry keys.
The following table lists the services of Acronis Backup and the privileges for their accounts.

3.5 Full, incremental and differential backups
Acronis Backup provides the capability to use popular backup schemes, such as
Grandfather-Father-Son and Tower of Hanoi, as well as to create custom backup schemes. All backup
schemes are based on full, incremental and differential backup methods. The term "scheme" in fact
denotes the algorithm of applying these methods plus the algorithm of the archive cleanup.
Comparing backup methods with each other does not make much sense because the methods work
as a team in a backup scheme. Each method should play its specific role according to its advantages.
A competent backup scheme will benefit from the advantages of all backup methods and lessen the
influence of all the methods’ shortcomings. For example, weekly differential backup facilitates
archive cleanup because it can be easily deleted along with the weekly set of daily incremental
backups depending on it.
Backing up with the full, incremental or differential backup method results in a backup (p. 238) of the
corresponding type.
Full backup
A full backup stores all data selected for backup. A full backup underlies any archive and forms the
base for incremental and differential backups. An archive can contain multiple full backups or consist
of only full backups. A full backup is self-sufficient - you do not need access to any other backup to
recover data from a full backup.
It is widely accepted that a full backup is the slowest to do but the fastest to restore. With Acronis
technologies, recovery from an incremental backup may be not slower than recovery from a full one.
A full backup is most useful when:
you need to roll back the system to its initial state
this initial state does not change often, so there is no need for regular backup.
Example: An Internet cafe, school or university lab where the administrator often undoes changes
made by the students or guests but rarely updates the reference backup (in fact, after installing
software updates only). The backup time is not crucial in this case and the recovery time will be
minimal when recovering the systems from the full backup. The administrator can have several
copies of the full backup for additional reliability.
Incremental backup
An incremental backup stores changes to the data against the latest backup. You need access to
other backups from the same archive to recover data from an incremental backup.
An incremental backup is most useful when:
you need the possibility to roll back to any one of multiple saved states
the data changes tend to be small as compared to the total data size.

It is widely accepted that incremental backups are less reliable than full ones because if one backup
in the "chain" is corrupted, the next ones can no longer be used. However, storing multiple full
backups is not an option when you need multiple prior versions of your data, because reliability of an
oversized archive is even more questionable.
Example: Backing up a database transaction log.
Differential backup
A differential backup stores changes to the data against the latest full backup. You need access to
the corresponding full backup to recover the data from a differential backup. A differential backup is
most useful when:
you are interested in saving only the most recent data state
the data changes tend to be small as compared to the total data size.
The typical conclusion is: "differential backups take longer to do and are faster to restore, while
incremental ones are quicker to do and take longer to restore." In fact, there is no physical difference
between an incremental backup appended to a full backup and a differential backup appended to
the same full backup at the same point of time. The above mentioned difference implies creating a
differential backup after (or instead of) creating multiple incremental backups.
An incremental or differential backup created after disk defragmentation might be considerably larger than
usual because defragmentation changes file locations on the disk and the backup reflects these changes. It is
recommended that you re-create a full backup after disk defragmentation.
The following table summarizes the advantages and shortcomings of each backup type as they
appear based on common knowledge. In real life, these parameters depend on numerous factors
such as the amount, speed and pattern of data changes; the nature of the data, the physical
specifications of the devices, the backup/recovery options you set, to name a few. Practice is the
best guide to selecting the optimal backup scheme.
3.6 What does a disk or volume backup store?
A disk or volume backup stores a disk or a volume file system as a whole and includes all of the
information necessary for the operating system to boot. It is possible to recover disks or volumes as a
whole from such backups as well as individual folders or files.
Windows
A volume backup stores all files and folders of the selected volume independent of their
attributes (including hidden and system files), the boot record, the file allocation table (FAT) if it
exists, the root and the zero track of the hard disk with the master boot record (MBR).
A disk backup stores all volumes of the selected disk (including hidden volumes such as the
vendor's maintenance partitions) and the zero track with the master boot record.
The following items are not included in a disk or volume backup (as well as in a file-level backup):
The swap file (pagefile.sys) and the file that keeps the RAM content when the machine goes
into hibernation (hiberfil.sys). After recovery, the files will be re-created in the appropriate
place with the zero size.
Windows shadow storage. The path to it is determined in the registry value VSS Default
Provider which can be found in the registry key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BackupRestore\FilesNotToBa
ckup. This means that in operating systems starting with Windows Vista, Windows Restore
Points are not backed up.
Linux
A volume backup stores all files and directories of the selected volume independent of their
attributes, a boot record, and the file system super block.
A disk backup stores all disk volumes as well as the zero track with the master boot record.
With the sector-by-sector (raw mode) option enabled, a disk backup stores all the disk sectors. The
sector-by-sector backup can be used for backing up disks with unrecognized or unsupported file
systems and other proprietary data formats.
3.7 Backup and recovery of dynamic volumes
(Windows)
This section explains in brief how to back up and recover dynamic volumes (p. 244) using Acronis
Backup.
A dynamic volume is a volume located on dynamic disks (p. 243), or more exactly, on a disk group (p.
243). Acronis Backup supports the following dynamic volume types/RAID levels:
simple/spanned
striped (RAID 0)
mirrored (RAID 1)
a mirror of stripes (RAID 0+1)
RAID-5.
Backing up dynamic volumes
Dynamic volumes are backed up in the same way as basic volumes. When creating a backup plan
through the GUI, all types of volumes are available for selection as Items to back up. When using the
command line, specify the dynamic volumes with the DYN prefix.
Command line examples
acrocmd backup disk --volume=DYN1,DYN2 --loc=\\srv1\backups
--credentials=netuser1,pass1 --arc=dyn1_2_arc
This will back up volumes DYN1 and DYN2 to a network shared folder.
acrocmd backup disk --volume=DYN --loc=\\srv1\backups --credentials=netuser1,pass1
--arc=alldyn_arc
This will back up all dynamic volumes of the local machine to a network shared folder.
To unallocated space of a basic disk.
To a disk which has not been initialized.
Recovery over an existing volume
When a dynamic volume is recovered over an existing volume, either basic or dynamic, the
target volume’s data is overwritten with the backup content. The type of target volume (basic,
simple/spanned, striped, mirrored, RAID 0+1, RAID-5) will not change. The target volume size has
to be enough to accommodate the backup content.
Recovery to disk group unallocated space
When recovering a dynamic volume to disk group unallocated space, the software preserves the
volume's original type and size. If the disk group configuration does not allow for the original
volume type, the volume will be recovered as a simple or spanned volume. If this volume does
not fit the unallocated space, the volume will be resized by decreasing its free space.
Examples of when the disk group configuration does not allow the original type of the volume
Example 1. The group contains fewer disks than is required for the dynamic volume. Assume you
are going to recover an 80 GB RAID-5 volume that had resided on three disks, to a disk group
consisting of two disks. The total size of unallocated space is 100 GB: 40 GB on the first disk and
60 GB on the second. The RAID-5 volume will be recovered as a spanned volume across two
disks.
Example 2. Unallocated space distribution does not allow recovery of certain types of dynamic
volumes. Assume you are going to recover a 30 GB striped volume to a disk group consisting of
two disks. The total size of unallocated space is 50 GB: 10 GB on the first disk and 40 GB on the
second. The striped volume will be recovered to the second disk as simple.
Recovery to a disk that has not been initialized
In this case, the target disk will be automatically initialized to the MBR partitioning style. The
dynamic volumes will be recovered as basic ones. If the volumes cannot fit into unallocated
space, they will be proportionally resized (by decreasing their free space).
The table below demonstrates the resulting volume types depending on the backed-up source and
the recovery target.
Moving and resizing volumes during recovery
You can manually resize the resulting basic volume during recovery, or change the volume's
location on the disk. A resulting dynamic volume cannot be moved or resized manually.
Before recovering dynamic volumes to bare metal you should create a disk group on the target
hardware.
You also might need to create or increase unallocated space on an existing disk group. This can be
done by deleting volumes or converting basic disks to dynamic.
You might want to change the target volume type (basic, simple/spanned, striped, mirrored, RAID
0+1, RAID 5). This can be done by deleting the target volume and creating a new volume on the
resulting unallocated space.
Acronis Backup includes a handy disk management utility which enables you to perform the above
operations both under the operating system and on bare metal. To find out more about Acronis Disk
Director Lite, see the Disk management (p. 181) section.
3.8 Support for Advanced Format (4K-sector) hard disks
Acronis Backup can back up hard disks with a sector size of 4 KB (known as Advanced Format disks),
as well as traditional hard disks that have 512-byte sectors.
Acronis Backup can recover data from one disk to another as long as both disks have the same logical sector size. (This is the sector size presented to the operating system.) Acronis Backup automatically
aligns the disk’s volumes (p. 112) if necessary. This way, the start of a cluster in the file system always
matches the start of a physical sector on the disk.
The disk management (p. 181) functionality of Acronis Backup is not available for disks with a 4-KB
logical sector size.
Determining the logical sector size
By disk specification
Development of the Advanced Format technology is coordinated by the International Disk Drive
Equipment and Materials Association (IDEMA). For more details, see
http://www.idema.org/?page_id=2.
In terms of the logical sector size, IDEMA specifies two types of Advanced Format disks:
512 Byte emulation (512e) disks have a 512-byte logical sector size. These disks are supported in
Windows starting with Windows Vista, and in modern Linux distributions. Microsoft and Western
Digital use the term “Advanced Format” exclusively for this type of disk.
4K native (4Kn) disks have a 4-KB logical sector size. Modern operating systems can store data on
these disks, but generally cannot boot from these disks. These disks are commonly external
drives with USB connection.
By running the appropriate command
To find out the logical sector size of a disk, do the following.
1. Make sure that the disk contains an NTFS volume.
2. Run the following command as an administrator, specifying the drive letter of the NTFS volume:
fsutil fsinfo ntfsinfo D:
3. Examine the value in the Bytes Per Sector line. For example, the output may be the following:
Acronis Backup can back up and recover machines that use 64-bit Unified Extensible Firmware
Interface (UEFI) in the same way as it does for machines that use BIOS for booting.
This applies to both physical and virtual machines, no matter if the virtual machines are backed up at
a hypervisor level or from inside a guest OS.
Backup and recovery of devices that use 32-bit UEFI are not supported.
For details about transferring Windows machines between UEFI and BIOS, see "Recovering
BIOS-based systems to UEFI-based or vice versa" (p. 117).
Limitations
WinPE-based bootable media of a version earlier than 4.0 do not support UEFI booting.
Acronis Active Restore (p. 237) is not available on UEFI machines.
Acronis Startup Recovery Manager (ASRM) (p. 237) on UEFI machines can be activated only in
Windows.
3.10 Support for Windows 8
This section describes how Acronis Backup supports features that are introduced in the Windows 8
operating system.
The information in this section also applies to Windows 8.1 and Windows Server 2012 R2.
Limitations
Acronis Disk Director Lite (p. 181) is not available under Windows 8.
Disk management operations under bootable media may work incorrectly if storage spaces are
configured on the machine.
The Windows To Go feature of Windows 8 is not supported.
WinPE 4.0 and WinPE 5.0
Acronis Media Builder can create bootable media based on these versions of Windows Preinstallation
Environment (WinPE).
These bootable media support new features of Windows 8 and Windows Server 2012 (see later in
this section). They can boot on machines that use Unified Extensible Firmware Interface (UEFI).
To create bootable media based on these versions of WinPE, you need Windows Assessment and
Deployment Kit (ADK). For more details, see the “WinPE-based bootable media” (p. 173) section.
UEFI Secure Boot
On a machine that runs Windows 8 and uses UEFI, the Secure Boot feature of UEFI may be turned on.
Secure Boot ensures that only trusted boot loaders can boot the machine.
By using Acronis Media Builder, you can create a bootable media that has a trusted boot loader. To
do this, choose to create a 64-bit Linux-based media or a 64-bit media based on WinPE 4 or later.
