Topics:
•Avamar system overview
•Data deduplication
•Security and networking
An Avamar system is a client/server network backup and restore solution.
An Avamar system consists of one or more Avamar servers and the network servers or desktop clients that back up data to those servers. The Avamar system provides centralized management through the Avamar Administrator graphical management console software application.
Avamar is a hard disk based IP network backup and restore solution. Avamar servers use internal hard disk storage. An Avamar server is a logical grouping of one or more nodes that is used to store and manage client backups.
Hardware manufacturers typically call their equipment servers (for instance, the Dell PowerEdge 2950 server). In the context of an Avamar system, this equipment is called a node. An Avamar node is a self-contained, rack-mountable, network-addressable computer that runs Avamar server software on the Linux operating system.
Avamar ensures fault tolerance by managing disk drive space in units of space called stripes.
In the Avamar system, an object is a single instance of deduplicated data. Each Avamar object inherently has a unique ID. Objects are stored and managed within stripes on the Avamar server.

Introduction 21
3.Disk drive storage on the node.
4.Stripe on the disk drive.
5.Object on the stripe.
All Avamar servers store client backups and also provide essential processes and services that are required for client access and remote system administration.
Avamar servers are available in either single-node or scalable multi-node configurations. For the most part, when using Avamar Administrator management console software, all Avamar servers look and behave the same. The main differences among Avamar server configurations are the number of nodes and disk drives that are reported in the server monitor.
Documenting specific differences in Avamar server hardware configurations is beyond the scope of this guide. Whenever specific limitations and best practices for certain configurations are known, they are noted. However, these occasional notes should not be considered definitive or exhaustive. Consult an Avamar Sales representative or an Avamar reseller for more information about specific hardware.
The primary building block in any Avamar server is a node. Each node is a self-contained, rack-mountable, network-addressable computer that runs Avamar server software on the Linux operating system.
Nodes can also contain internal storage in the form of hard disk drives. If the node is configured with internal storage (that is, a singlenode server), it is internally mirrored to provide robust fault tolerance.
There are three types of nodes.
Utility node
A utility node is dedicated to scheduling and managing background Avamar server jobs. In scalable multi-node Avamar servers, a single utility node provides essential internal services for the server, such as:
•Management Console Server (MCS)
•External authentication
•Network Time Protocol (NTP)
•Web access
Because utility nodes are dedicated to running these essential services on multi-node Avamar servers, they cannot be used to store backups. Single-node Avamar servers combine all of the features and functions of utility and storage nodes on a single node.
Storage nodes
Storage nodes are nodes that store backup data. Multiple storage nodes are configured with multi-node Avamar servers which are based on performance and capacity requirements. You can add storage nodes to an Avamar server over time to expand performance with no downtime.
Avamar clients connect directly with Avamar storage nodes. Client connections and data are load that is balanced across storage nodes.
NDMP Accelerator
An NDMP Accelerator node is a specialized node that uses NDMP to provide data protection for certain NAS devices, including the EMC Celerra® IP storage systems and Network Appliance filers.
The major Avamar server functional blocks include the data server, Management Console Server (MCS), and the EM Tomcat server (EMT). The following figure illustrates the interaction of these components within the server and with other Avamar components.

Introduction 25
Avamar Client Manager
Avamar Client Manager is a web-based management application that provides centralized Avamar client administration capabilities for larger businesses and enterprises. Avamar Client Manager helps with the management of large numbers of Avamar clients.
Avamar Client Manager works with Avamar clients on a supported native operating system and Avamar clients on a supported operating system running in a VMware virtual machine. Avamar Client Manager cannot work with Avamar clients through virtual center, virtual machine, or virtual proxy configurations. The Avamar Client Manager UI displays supported Avamar clients and hides all unsupported clients.
Avamar Desktop/Laptop
Avamar Desktop/Laptop is a version of the Avamar client software that adds enhanced features for enterprise desktop and laptop computers.
The Avamar Desktop/Laptop features are designed to improve the functionality of Avamar client for Windows and Macintosh desktops and laptops. Many of the features are also supported on qualifying Linux computers.
Avamar Desktop/Laptop functionality is available through two user interfaces:
•The client local user interface (client UI) is installed on the client computer when you install either the Avamar Client for Windows or the Avamar Client for Mac OS X. With the client UI, an Avamar icon appears in the notification area ("system tray") on Windows computers or on the menu bar on Mac computers. Right-click the icon on Windows or click the icon on Mac to open the client menu, which provides access to backup, restore, program settings, and logs.
•Use the web browser user interface (web UI) to start an on-demand backup or restore, view backup and restore activity for a client computer, or configure other backup settings for a client computer.
Avamar Installation Manager
The Avamar Installation Manager user interface is part of the AvInstaller software that Customer Support installs on the utility node during an Avamar server software installation or upgrade. Use the Avamar Installation Manager to install and upgrade software on the Avamar server.
Avamar Downloader Service
The Avamar Downloader Service manages the process of checking for and downloading Avamar server software updates. The Avamar Downloader Service software runs on a stand-alone Microsoft Windows server that allows network access to Avamar sites on the Internet and to all Avamar servers at a site.
Avamar Web Restore
Avamar Web Restore provides access to the following functionality:
•Search for or browse backed up directories and files to restore.
•Download Avamar client software.
•View Avamar product documentation that is stored on the Avamar server.
•Open the Avamar Administrator management console software.
You can store backups on either the Avamar server or a Data Domain system. Backup metadata is stored on the Avamar server.
Before you can store backups on a Data Domain system, add the Data Domain system to the Avamar configuration by using Avamar Administrator. Then select the Data Domain system in the plug-in options when you perform an on-demand backup or when you create a dataset for a scheduled backup. You can also use the command line interface (CLI) to perform backups to a Data Domain system.
The steps to restore backups are the same whether you restore from the Avamar server or a Data Domain system. The restore process determines the location of the backup and restores the backup.
Support for Data Domain Cloud Tier was initiated in Avamar 7.4. DD Cloud Tier moves data from Data Domain to the cloud. From the Avamar Administrator, you can configure cloud tier to move Avamar backups from Data Domain to the cloud, and perform seamless recovery of these backups.
Data Domain Cloud Tier Disaster Recovery support was initiated with Avamar 7.5. You can recover backups from the cloud in case of the loss of a Data Domain and also recover an Avamar server from the cloud.
26 Introduction
The Avamar and Data Domain System Integration Guide provides more information about Data Domain systems in an Avamar environment, including detailed steps to add a Data Domain system to the Avamar configuration.
Data deduplication is a key feature of the Avamar system. Data deduplication ensures that each unique sub-file, variable length object is stored only once across sites and servers.
During backups, Avamar client software examines the client file system and applies a data deduplication algorithm that identifies redundant data sequences and breaks the client file system into sub-file, variable length data segments. Each data segment is assigned a unique ID.
The client software then determines whether this unique ID has already been stored on the Avamar server. If this object resides on the Avamar server, a link to the stored object is referenced in the backup.
Once an object has been stored on the server, it is not sent over the network again, no matter how many times it is encountered on any number of clients. This feature significantly reduces network traffic and provides for greatly enhanced storage efficiency on the server.
Figure 4. Data deduplication
1.Break data into atoms (variable length segments of file data).
2.Send and store each atom only once.
3.Up to 500 times daily data reduction in the Avamar backup repository.
The following sections provide an overview of key Avamar security and networking features. The Avamar Product Security Guide provides full details on product security and network configuration.
To provide enhanced security, Avamar can encrypt all data that is sent between clients and the server “in flight.”
You can set the encryption level on a client-by-client basis in client properties, or for an entire group of clients in group properties. You can also disable “in-flight” encryption entirely.
Each Avamar server can also be configured to encrypt data that is stored on the server “at rest.” The decision to encrypt all data that is stored in an Avamar server is typically a one-time decision that is made when the server is initially deployed at a customer site.
Introduction 27
Internet Protocol (IP) is a set of communication rules for routing traffic across networks to addressable devices like Avamar system components. The Avamar system supports both Internet Protocol Version 4 (IPv4) and IPv6 address notation.
IPv4 notation
IPv4 notation is displayed as four octets, that are 1- to 3-digit base 10 numbers in a range of 0 to 255. Each octet is separated by periods and represents 8 bits of data for a total address space of 32 bits.
A subnet mask identifies a range (a subnet) of IP addresses on the same network. For Avamar purposes, the subnet mask is /24, representative of a 255.255.255.0 netmask.
An example of IPv4 address and subnet mask is10.99.99.99/24.
IPv4 notation cannot be abbreviated. If an octet has zero (0) value, use a 0 in that octet.
IPv6 notation
IPv6 notation is displayed as 16 octets, that are 2-digit hexadecimal (base 16) numbers in a range of 00 to FF. IPv6 notation combines octets by pairs into eight groups that are separated by colons, each group representing 16 bits of data for a total address space of 128 bits.
For Avamar purposes, the subnet mask (called prefix in IPv6) is /64.
An example IPv6 address and prefix is 2001:0db8:85a3:0042:1000:8a2e:0370:7334/64.
As for a group with zero (0) value, IPv6 notation is different from IPv4 that can be abbreviated. For example, the following is a valid IPv6 address and prefix: 2001:db8:abcd:0012::0/64.
Avamar IP configurations
In the Avamar user interface, an IP address may be displayed in either IPv4 or IPv6 notation. The displayed value depends on how that particular component was configured when the hardware and software were installed.
IPv4 and IPv6 are not interoperable. They operate in separate stacks (that is, parallel, independent networks).
Avamar can be set up in a dual stack configuration. In that case, each Avamar component may have an IPv4 address, an IPv6 address, or both (one primary and the other secondary). The Avamar user interface may display a component's primary address or both dual stack addresses. For example, the following IP address for a particular device indicates that it is configured as dual stack:
10.99.99.99/24,2001:db8:abcd:0012::0/64.
Encrypted traffic using the TLS 1.0 and 1.1 protocols is no longer supported. Browsers, clients, and other components that require these protocols are not allowed to connect to the server. Only TLS 1.2 encryption is supported.
The SSH configuration has been modified to remove weak MAC algorithms that are used for SSH connections.
The following MAC algorithms are used for SSH connections:
•hmac-sha2-512-etm@openssh.com
•hmac-sha2-512
•hmac-sha2-256-etm@openssh.com
•hmac-sha2-256
•umac-128-etm@openssh.com
•umac-128@openssh.com
•hmac-ripemd160-etm@openssh.com
•hmac-ripemd160
NOTE: Older versions of SSH clients, such as PuTTY or Plink, use weak MAC algorithms for an SSH connection and must be upgraded. To view the latest release of PuTTY, see http://www.putty.org/
