Introduction

Paragon Hard Disk Manager™ 15 Premium is an integrated set of powerful tools that is specially designed to tackle most of the problems you might face while using PC. Its functionality covers all aspects of a computer life cycle beginning from carrying out all the necessary partitioning operations to install the system from scratch and providing its data reliable protection to secure utilization of an outdated hard disk.

In this manual you will find the answers to many of the technical questions, which might arise while using the program.

Our company is constantly releasing new versions and updates to its software, that's why images shown in this manual may be different from what you see on your screen.

What’s New in Hard Disk Manager 15

Agentless protection of Hyper-V guest machines. Unlike traditional backup tools designed to work with physical machines, our product can operate at the virtualization layer, employing MS VSS (Volume Shadow Copy Service) to agentlessly backup/restore any guest machine of Hyper-V. Thus our solution doesn’t need an agent on a target virtual machine to create its point-in-time copy including its configuration, operating system, apps, etc.

Embedded Recovery Media Builder (RMB) 3.0. Instead of two utilities downloaded from Paragon's website (BMB and RMB), the new RMB 3.0 is now embedded into the product. Combining the best of the two utilities, it can boast more options, usability, and stability:

-Prepares Linux or WinPE-based bootable environment on a USB thumb drive or in an ISO image;

-Doesn’t obligatory require Windows Assessment and Deployment Kit (ADK) or Automated Installation Kit (WAIK) on Windows 7 and later platforms;

-Can build WinPE-based media on Windows XP, Vista, Server 2003 if there’s WAIK installed in the system;

-Allows injecting additional drivers for storage devices, network controllers, USB controllers, or system during setup;

-Enables to set up a network connection with a pre-mounted network share during setup;

-Prepares hybrid (both, uEFI and BIOS compatible) 64-bit recovery environment on flash or in an ISO image.

File-level backup/restore for virtual containers (pVHD, VHD, VHDX, VMDK). As promised, Paragon's innovative backup imaging technology has been further improved and now opens up the option of creating file-level virtual containers (full, incremental, as well as file complements), thus offering users rock-stable, high-performance technology to protect system and data not only on sector-level, but file-level as well. This means that the old PBF format will eventually leave the scene.

Refactored P2V Restore Wizard. Instead of the old PBF-based backup images, you can now use virtual containers (pVHD, VHD, VHDX, VMDK) to do P2V migration directly out of backup images. The use of virtual containers has enabled to significantly improve performance and usability for this type of migration operations.

Wiping SSD (Solid State Drive). As you know SSD stores data differently from hard disks, thus existing disk sanitization techniques originally used for HDDs don't work on SSDs because the internal architecture of an SSD is very different from that of a hard disk. Reliable SSD sanitization requires built-in, verifiable sanitize operations. After some research on the issue, our company has improved our disk wiping technology and can now guarantee irreversible secure data destruction on SSD storage devices.

This feature is only available for the Linux recovery environment at the moment.

Support of Hyper-V 2008 R2, 2012 R1, 2012 R2 (Generation 1 and 2) for P2V scenarios.

Predefined views. The Windows 8 like streamlined, tile-oriented interface has been enhanced by predefined views, which enable to adjust the working environment to particular customer needs.

Product Components

In order to cope with different tasks, the product contains several components:

Windows based set of utilities is the crucial part of the product. With the help of an easy to use launcher you may find and run tasks of any complexity in the field of data and system protection, hard disk partitioning and cloning, etc.

Linux/DOS based recovery environment is a multi-platform bootable media that enables to run utilities under Linux or PTS DOS, and that way to get access to your hard disk for maintenance or recovery purposes. Both platforms have their strong sides, for instance Linux can boast support of FireWire (i.e. IEEE1394) or USB devices. It enables to burn CD/DVD discs. However there can be some difficulties with detecting new hardware. DOS in its turn has no problems of that kind but is limited in features. The Linux/DOS recovery environment requires no installation and can be of great help when the system fails to boot. Besides it offers a Windows XP like environment.

WinPE based recovery environment. Especially for keen followers of Windows, our product offers the option to prepare a WinPE based bootable media. Unlike the Linux/DOS recovery environment it can boast an excellent hardware support and the same interface as the Windows version can. However its system requirements are much tougher.

Features Overview

This chapter dwells upon key benefits and technical highlights of the product.

Features

Let us list some of the features:

User Friendly Fault Minimizing Interface

Graphical representation of the data to gain a better understanding.

A handy Launcher to easily find and run the required tasks.

Comprehensive wizards to simplify even the most complex operations.

A context sensitive hint system for all functions of the program.

Previewing the resulting layout of hard disks before actually executing operations (so-called virtual operations).

Backup Facilities

Archive Database to help the user easily manage backup images (get properties, add, delete, mount, etc.).

Copyright© 1994-2014 Paragon Software GmbH. All rights reserved.

9

This feature is only available for the Windows installation of the program.

Available location for backup images:

-Backup to local mounted partitions.

-Backup to local unmounted (without drive letter assigned) partitions.

-Backup to an external mounted storage to provide for a higher level of data protection and system independence.

-Backup to a special secured place on the hard disk called the Backup Capsule that has an independent system layout (e.g. a separate partition) and will stay operable should the active file system be damaged. To avoid an accidental removing or unauthorized access of the backup data, this partition is hidden and thus cannot be mounted in the operating system.

-Backup to external media (CD/DVD) to guarantee a high level of data protection as long as the backup media is kept secure.

-Backup to a network drive to stand a better chance of success in case of a hard disk failure.

-Backup to an FTP/SFTP server to provide a new level of system and data protection.

Bootable Backup Capsule to get the choice to launch the Linux or PTS DOS recovery environment every time you start up the computer. With its help you will be able to run utilities under Linux or PTS DOS, and that way to get access to your hard disk for maintenance or recovery purposes.

For PBF images:

Smart Backup Wizard to secure system and data with the minimal efforts possible. With a unique intelligent work algorithm and a highly intuitive user interface, you can easily back up exactly what you need - the whole system, e-mail databases (MS Outlook, Express, Windows Mail) media files or office documents of the My Documents folder, or any other files and folders.

Differential backup to a sector image to only archive changes since the last full sector-based image, thus considerably saving the backup storage space. To restore this kind of backup you will require a full image and one of its differentials.

Incremental backup to a sector image is a further way of optimizing the process of disk imaging. Unlike differentials, it may not only contain data changed since the time of creating a full sector-based archive, but one of its increments as well, thus allowing to save more time and the backup storage. Introduction of a special index file that stores backup meta-information minimizes time and resources to create this type of archives.

Incremental backup to a file image to only archive changes since the last full or incremental file-based image. An incremental image is smaller and takes less time to create, but you will require the initial full image and all of its increments to restore the latest point of this kind of backup.

File backup to a sector image. It is a unique technology on the market so far that bridges two principally different approaches of the data backup: the file-based backup and the disk imaging backup. With its help you can now create a sector-based backup of your system to get it back on track in minutes in case of a virus attack or a hardware malfunction and then just make file-based incremental images to the previously created sectorbased backup to keep updated only information that is critical for you. Thus you will considerably save your system resources.

Basic Concepts

This chapter explains terms and ideas that show how the program works. To understand these helps to obtain a general notion of the operation performance and makes it easier for the user to operate the program.

System and Data Protection

The data protection issue is a growing cause of worrying for more and more people today. Indeed, it is hardly to find a person who will be particularly happy when all precious information on the hard disk is irreversible lost as a result of its malfunction. So how this tragedy can be prevented?

File Backup versus Sector Backup

Since the advent of the computer age people were in the search of ways to guarantee data safety. As a result we’ve got now two principal approaches: the file-based backup and the sector-based backup. The main difference between the two lies in the way data is treated.

A sector-based backup operates with an image (or a snapshot) of the whole disk system or its separate partitions. It not only includes the contents of all user-made files, but additionally contains the exact structure of directories, information about file allocation, file attributes and other related data. Thus it enables to successfully process system or encrypted partitions of any file system type, no matter what kind of information they contain.

In contrast, a file-based backup takes into account a file system structure and only functions on a file or folder level. So it is very efficient when archiving separate files or folders, but in no way will help you back up a system partition.

You should understand pretty well that each of the two approaches is only good when properly chosen. In the comparison table below you can see when this or that approach will suit you at most.

It is much slower when processing large amount of data.

Backup Types

At the present moment the market is offering various types of backup imaging to meet the needs of any user. Besides supporting them all, our program offers a unique backup type, called File Increment to a Sector Backup.

Full, Differential, and Incremental Sector Backups

A full sector-based backup image includes all contents of a partition or a hard disk at the moment of its creation. If you roll back your system to the initial state on a regular basis, that’s exactly what you’re looking for. But if you want to have multiple backup archives of the same partition reflecting certain time stamps, unchanged data will inevitable be duplicated in all archives and take additional space on backup media. To tackle this issue there has been developed a supplementary technique called Differential Sector Backup.

A differential archive only contains data changed since the time of creating a full archive, which forms a base (or a parental image) in this case, thus considerably saving your system resources. It is realized by the exact bit-wise comparison of the previous partition's data (saved in the parental image) with the current data (that is actually the partition itself). To restore this kind of backup you will require a full image and one of its differentials, what is very convenient.

This function is only available for single primary and logical partitions.

Incremental archive is a further way of optimizing the process of disk imaging. Unlike differentials, it may not only contain data changed since the time of creating a full sector-based archive, but one of its increments as well, thus allowing to save more time and the backup storage. The main principal here is the shorter the interval between increments, the less data is backed up. In general this type of backup is great except for one thing – when you restore an incremental archive there will be processed the initial full image and all increments between, which depending on the size of your backup chain, may take plenty of time. Anyway unlike backups, the restore operation is an emergency, which might not happen at all.

Paragon’s incremental sector-based archive employs an innovative technology that significantly improves the backup performance. Its core is in introduction of a special index file (.pfi) that keeps meta-information on the corresponding incremental image. It’s much smaller than the image itself and is used to calculate the difference between the current and previous state of a backup object. Thus, when you’re going to do an increment to a full archive of your system

26

partition stored on the network, only its index file is processed over the net (a couple of megabytes at most), not the entire image, which minimizes both, the network traffic and backup time. Another new thing is change of a backup format – all increments are saved in .vhd (Virtual Hard Drive) containers.

Please note that the current version of the product has a number of limitations regarding sector-based increments:

Increments can only be created for full archives of the new type (with a .pfi index file). Any of our flagship products since Hard Disk Manager 12 supports this functionality;

Increments can only be created for full archives stored on a local mounted drive or a network share;

Increments cannot be created for archives of entire GPT disks;

Increments can only be restored under Windows (if no restart is needed) or WinPE;

Increments cannot be processed with the Synthetic Backup Wizard;

Increments cannot be processed with the Check Archive Integrity Wizard;

Increments cannot be processed with the Create File Complement Wizard;

Increments cannot be browsed in Volume Explorer;

Increments can only be used with our software;

Increments cannot be compressed;

Increments cannot be encrypted;

Increments cannot be splitted.

Full and Incremental File Backups

A full file-based archive only contains files and folders. It is really efficient when backing up an e-mail database or particular documents, as no redundant data is processed. But if you care about maintaining a files history, you can benefit from one more supplementary technique called Incremental File Backup.

An incremental archive only contains data changed since the time of creating a full or incremental file-based archive. It is smaller and takes less time to create, but you will require the initial full image and all of its increments to restore the latest point of this kind of backup.

File Increment to a Sector Backup

File Increment to a Sector Backup is a unique technology on the market so far that bridges two principally different approaches of the data backup: the file-based backup and the sector-based backup. With its help you can now create a sector-based backup of your system to get it back on track in minutes in case of a virus attack or a hardware malfunction and then just make file-based incremental images to the previously created sector-based backup to keep updated only information that is critical for you. Thus you will considerably save your system resources.

Backup Storage

Our program supports several techniques of storing backup images. Let’s take a closer look at them all to understand what kind of storage is able to provide better security:

You can place a backup image to a local partition. Despite the fact that it is the most convenient way, try not to use it. You can delete your backup just by accident or lose it as a result of a hardware malfunction, or a virus attack;

You can place a backup image to an external mounted storage to provide for a higher level of data protection and system independence;

You can place a backup image to a special secured place on the hard disk called the Backup Capsule that has an independent system layout (e.g. a separate partition) and will stay operable should the active file system be damaged. To avoid an accidental removing or unauthorized access of the backup data, this partition is hidden and thus cannot be mounted in the operating system. However it won’t help you in case of a hardware malfunction;

You can place a backup image to external media (CD/DVD) to guarantee a high level of data protection as long as the backup media is kept secure;

You can place a backup image to a network drive to stand a better chance of success in case of a hard disk failure. Moreover, by storing it on a special-purpose server you may be pretty sure nothing will happen to it;

Finally you can place a backup image to an FTP server to provide a new level of system and data protection.

Known Issues on FTP/SFTP

1.You need to check out yourself Windows Firewall or programs of this kind let our program work with the required port (21 by default).

2.You cannot restore data selectively (with Restore Wizard) from an FTP/SFTP server.

3.You can browse an FTP server in the passive mode only.

4.Parallel access to several FTP/SFTP servers is limited - only one password for all servers is available.

Adaptive Restore

Technology Background

Windows family operating systems are notorious for their excessive sensibility to hardware, especially when it turns to replacement of such a crucial device as HDD controller or motherboard – actually Windows will most likely fail to boot as a result of this operation.

In 2008 our company came with an exclusive technology called Paragon Adaptive Restore™. Initially aimed at restore of Windows Vista or Server 2008 from a backup to a different hardware configuration, its current realization, available in the P2P Adjust OS Wizard, enables to make any Windows OS since XP bootable on dissimilar hardware by allowing automatic injection of all required drivers and the other actions crucial for this type of migration.

Technology Concept

Let’s take a closer look at how Paragon Adaptive Restore works.

As you see, successful migration of a Windows system to a different hardware platform involves several actions:

1.Change of the Windows kernel settings according to the new configuration. The program detects the given hardware profile and automatically installs the appropriate Windows HAL and kernel.

2.Installation of drivers for boot critical devices. The program detects those without drivers and automatically tries to install lacking drivers from the built-in Windows repository. If there’s no driver in the repository, it prompts the user to set a path to an additional driver repository, strongly recommending not to proceed until all drivers for the found boot critical devices are installed. In case drivers for these devices are installed, but disabled, they will be enabled.

3.Installation of drivers for a PS/2 mouse and keyboard. This action will only be accomplished for Windows XP/Server 2003.

4.Installation of drivers for network cards. The program detects those without drivers and automatically tries to install lacking drivers from the built-in Windows repository. If there’s no driver in the repository, it prompts the user to set a path to an additional driver repository.

Copyright© 1994-2014 Paragon Software GmbH. All rights reserved.

29

These actions guarantee a Windows system will start up on dissimilar hardware. After the startup, Windows will initiate reconfiguration of all Plug'n'Play devices. It’s a standard procedure, so please don’t worry and prepare the latest drivers at this step to get the most out of the system.

Though all Windows systems have built-in driver repositories, please be prepared to have additional drivers when dealing with Windows XP/Server 2003, because for these systems they are very modest.

Technology Application

Let’s consider a number of situations when the Adaptive Restore technology can help you out:

If you need to migrate to a different hardware platform with minimal effort

If you need to upgrade hardware while keeping all programs and settings intact

If you need to replace failed hardware and cannot find an exact match for original system specifications

Known Issues

1.After transferring Microsoft Vista and later versions to different hardware, you will need to re-activate license of the system. It’s normal behavior as these systems keep tracking any change of hardware. Re-activation is legally justified in this case, as you transfer your system to another PC.

2.If you’ve installed several operating systems on one partition, we can only add drivers to the latest version of

OS. Microsoft highly recommends that you install an operating system on a separate partition.

3.Please note drivers are not cached during selection. That’s why if you select a driver to add to the system, but it’s already unavailable during the operation, the program will end the operation with an error.

System Virtualization

With new powerful x86 computers, system virtualization has become extremely popular. It’s a software technology that enables to run several virtual machines on one physical machine, providing resources of that single computer are shared across several environments. As a result one and the same physical computer can have multiple OSs and applications operating simultaneously, thus opening up enormous opportunities for both, business and home users, exactly:

Avoid underutilization of up-to-date powerful computers;

Increase flexibility of a physical infrastructure;

Provide for increased availability of hardware and applications;

Cut expenses on hardware and energy;

Guarantee smooth and cost saving system migration;

Enjoy working with old applications you can’t launch on your current PC;

Take advantage of having multiple operating systems on one Windows PC, including Linux, Mac OS X, etc.;

Forget about hunting for replacement of the failed hardware, and many more…

30

Known Issues

1.You should install integration services (e.g. VMware Tools) on the virtual system yourself. We only guarantee its smooth startup.

2.After transferring Microsoft Vista and later versions to a virtual disk, you will need to re-activate license of the system. It’s normal behavior as these systems keep tracking any change of hardware. Re-activation is legally justified in this case, as you transfer your system to another PC.

3.If your system hosts several Windows OSes, our program will find them all and automatically patch to run in a virtual environment. However we cannot guarantee smooth startup of all found Windows systems, but the guest OS, for its configuration parameters may be incompatible with the others.

Paragon Hot Processing & Volume Shadow Copy Service

Offline versus Online Data Processing

In the course of time there have been developed various methods of data processing. Despite different work concept, all of them can be divided into two principal groups: offline (cold) and online (hot) data processing techniques.

As the name infers, offline data processing can only be accomplished when the data is in consistent state (the operating system and all the applications are completely shut down). Actually it is the most preferable way of image creation or data cloning, since software can obtain an exclusive right to process data that guaranties high level of operating efficiency. However, the offline data processing is absolutely out of question when dealing with 24/7 production environments.

In contrast, online data processing enables to create a consistent snapshot even as the data is currently modified. It is particularly useful for systems with high availability requirements, but it won’t be accomplished until all active transactions are complete. The point is to provide a coherent state of all open files and databases involved in a process, taking into account that applications may still keep writing to disks. As a result an online data processing cannot boast high operating speed.

Our program supports both offline and online methods of data processing. As far as online method is concerned it offers its own hot processing algorithm together with the possibility to use snapshot technologies provided by the Microsoft VSS framework.

Paragon Hot Processing Technology

Paragon Hot Processing is an online copy/backup technology for Windows NT+ family operating systems. Developed back in 2001, nowadays it is integrated with all copy/backup solutions offered by the company.

Paragon Hot Processing is not exactly a snapshot technology, though it has much in common with it. During an online copy/backup, the program uses the kernel mode driver HOTCORE.SYS to intercept and control disk write activity of applications and the operating system. The hotcore driver as an integral part of the program is installed during the setup procedure (that’s why the system reboot is required to complete the setup procedure). For the most part the driver is in the idle mode until it is activated with the program. While in this mode it bypasses any calls having no effect on the overall system performance, but a few kilobytes of the system memory.

Paragon Hot Processing technology offers copy/backup of locked partitions and hard disks under Windows NT+ family operating systems providing both high operating efficiency as well as low hardware requirements.

It is not recommended to use Paragon Hot Processing with active SQL Server, Exchange or Oracle databases since the backup image contents may be corrupted.
