Chapter 1. Tivoli Storage Manager FastBackTivoli Storage Manager FastBack provides several functions for the purposes ofbacking up and restoring data with snapshots.All data is backed up at the disk block level in full and incremental snapshots.After data is backed up, data can be restored back to a disk, or mounted as avirtual volume for an individual file restore.Tivoli Storage Manager FastBack provides these services with three primaryservices: FastBack Client, FastBack Server, and FastBack Mount. FastBack Manageris the graphical user interface that you can use from a supported Windows orLinux operating system to manage the FastBack Server.FastBack Client is a service that runs on client systems (production servers) andbacks up used or changed disk blocks. FastBack Client is not an application in thesense of having a GUI or actions that you can initiate. Most activity is controlledby FastBack Server. The server hosts a repository that stores all backed up datareceived from the client systems. The server also initiates snapshot backups,scheduled backups, and defines all options for the back up process. You can alsorestore data from the server. Access to the FastBack Server should be restricted toIT personnel.Tivoli Storage Manager FastBack provides the following functionality:v Full snapshots of entire disks, and incremental snapshots of entire disks. Adefined set of disks to be backed up concurrently is called a client group. Aclient group can contain multiple disks from multiple clients.v Advanced scheduling features of backup. Schedules are combined with clientgroups to create policies. A policy can contain several client groups, and severalschedules. Client group, schedule, and policy creation are all controlled usingFastBack Server.v All snapshots use Copy-On-Write. Copy-On-Write ensures snapshot integrityand accuracy while a snapshot is being taken by copying blocks from a disk justbefore they are to be overwritten by an application.v (Windows only) Schedules can optionally provide Continuous Data Protection(CDP). CDP allows for point-in-time restores by backing up changed blocks inreal time, between snapshots. CDP is configured per schedule.v Data can be restored in several ways:– File-level recovery.– Volume restore, initiated by the FastBack Server. A volume restore restores anentire volume from a specific snapshot. – instant restore. instant restore is part of FastBack Mount. Like volume restore,entire volumes are restored to existing volumes. In addition, data can beaccessed near-instantaneously while an instant restore is in progress.– Mount a snapshot to a virtual volume through FastBack Mount. This virtualvolume can be its own disk, with its own drive letter, or it may be a directorywithin an existing real volume. File systems on virtual volumes can beaccessed and navigated as if the volume was a local disk. In this way, filescan be restored individually to a separate real volume.

System componentsTivoli Storage Manager FastBack consists of the following components andservices:FastBack Server (Windows only)A server dedicated to running Tivoli Storage Manager FastBack. TheFastBack Server performs block-level snapshots. The server connectsdirectly to the storage area network (SAN) and local area network (LAN),and, for direct-attached storage (DAS) environments, moves snapshot datathrough the LAN. If a SAN is present, the server can be configured tomove snapshot data directly through the SAN.The snapshot data is copied from the protected system, through theFastBack Server, and into the repository. The repository can be on anydesignated disk as a disk, volume, or folder repository. The FastBack Server provides the following functionality:v Tracking of all snapshots.v Transferring snapshot data through SAN or LAN.v Volume restoring and use of Tivoli Storage Manager FastBack for BareMachine Recovery through FastBack Manager.v Security with Active Directory and built-in mechanisms.FastBack ClientThis component backs up used or changed disk blocks.FastBack MountThis service enables the mounting of any snapshot volume from therepository. You can view the snapshot locally, with read-only access, on theclient system. FastBack Mount is used to restore individual files or folders(file-level restore) or volumes (instant restore). With FastBack Mount, youcan complete the following tasks:v Verify snapshotsv File or folder-level restore v Volume-level restorev Database verification v Back up to tapev (Linux only) Specify a local destination partitionFastBack Watchdog (Windows only)A service that monitors the status of the backup server. The servicedetermines if the server is down. If the status is down, the service sends anemail to the system administrator about the server status.FastBack DR Hub Server (Windows only)A server that stores the backup repository at an off-site location, oftenreferred to as a disaster recovery site. The FastBack Server replicates thebackup repository. The FastBack DR Hub Server works on top of anexisting standard FTP server.The FastBack DR Hub Server uses a proprietary protocol with the standardFTP protocol. The FastBack Disaster Recovery protocol uses the standardFTP over SSL to ensure a secure transfer of data.The FastBack DR Hub Server is sometimes referred to as the FastBackDisaster Recovery Hub Server, the FastBack Disaster Recovery Hub, andthe DR Hub Server.2Installation and User's Guide

FastBack Reporting (Windows only)A service that summarizes how repositories, policies, and snapshotsconsume resources in your network environment. FastBack Reporting usesthe Tivoli Common Reporting tool to run and view reports.In addition, Tivoli Storage Manager FastBack provides the following interfaces:FastBack ManagerFastBack Manager is a standalone, Java-based graphical user interface. Youcan use the FastBack Manager to initiate a variety of tasks, such as:vvvvvvvManaging the snapshot repositoryScheduling snapshotsDetermining the result of backup jobsMonitoring which snapshots are completed, in-process and pendingPerforming data recoveryMonitoring Tivoli Storage Manager FastBack system eventsConfiguring and managing user group privileges and securityauthentications for specific usersMultiple remote FastBack Manager sessions can be active simultaneouslyso different users can simultaneously access the FastBack Server. Central Control Station (Windows only)A Microsoft Foundation Class (MFC) graphical user interface that providesa view of status files stored for the FastBack DR Hub Server database.When at the disaster recovery location, you can use Central Control Stationwith FastBack Manager to administer all remote FastBack Servers.Administrative Command LineThe command line interface used to access Tivoli Storage ManagerFastBack functions. The Administrative Command Line is sometimesreferred to as the FastBack Shell.The following figure shows the high-level architecture of Tivoli Storage ManagerFastBack in the branches:Chapter 1.

Data deduplicationData deduplication is a method of eliminating redundant data in sequential-accessdisk (FILE) primary, copy, and active-data storage pools. One unique instance ofthe data is retained on storage media, and redundant data is replaced with apointer to the unique data copy. The goal of deduplication is to reduce the overallamount of time that is required to retrieve data by letting you store more data onvolumes and in folders, rather than on tape.FastBack data deduplication is a service that runs on the FastBack Server system.When you use data deduplication, extra disk I/O and processor resources arerequired. For more information about the hardware requirements related to datadeduplication, see “Hardware requirements” on page 19. To start FastBack data deduplication, you must identify a repository (either avolume or folder) as the data deduplication repository. Only one repository can beidentified for data deduplication. If you are going to identify a repository as thedata deduplication repository, you must complete this step when you create therepository. Data deduplication repositories and non-data deduplication repositoriesare mutually exclusive. Therefore, you cannot have a data deduplication repositoryand a non-data deduplication repository on the same FastBack Server. In addition,you cannot migrate from data deduplication repositories to non-data deduplicationrepositories, nor can you migrate from non-data deduplication repositories to datadeduplication repositories. For more information about identifying a repository fordata deduplication, see “Creating repositories” on page 85.Note: When using Tivoli Storage Manager FastBack, FastBack data deduplicationmight be referred to as dedupe. If you see the term dedupe, the term is areference to data deduplication.Note: Continuous Data Protection is not supported on repositories used with datadeduplication. Using data deduplication in a wide area network This Tivoli Storage Manager FastBack 6.1.1 version introduces deduplication forreplicated data that is sent between the FastBack Server and the FastBack DisasterRecovery Hub server. The deduplicated data is sent to the FastBack DisasterRecovery Hub server repository using wide area network (WAN) connections. TheTivoli Stora
