Info

Table 29. Planning your backups (continued)___ Decide what type of backup you want according to your needs. See the followingsections for more information:v “Performing an incremental, selective, or incremental-by-date backup” on page87v “Group backup: Backing up files from one or more file spaces” on page 96v “Performing an image backup” on page 102v “Backing up NAS file systems” on page 108v “Backing up the WebSphere Application Server (WAS)” on page 112___ If you are performing an image backup, ensure that you have accounted forunique considerations. See “Performing an image backup” on page 102 for moreinformation.___ For further backup considerations, see “Backup: Additional considerations” onpage 114.When to back up and when to archive filesWhen the backup-archive client backs up or archives a file, it sends a copy of thefile and its associated attributes to the server; however, backups and archives havedifferent goals.Use backups to protect against unforeseen damage to your files, and use archivesfor maintaining more permanent versions of your files.Backup data is managed by version, using predetermined policy based rules. Usingthese rules, the Tivoli Storage Manager administrator can control the following:v The number of versionsv The number of days each additional backup copy is keptv What happens to backup data versions when the file is deleted on the clientmachineEach copy of the file stored on the server is considered to be a separate and uniqueversion of the file.Archive is a powerful and extremely flexible mechanism for storing long termdata. Archive data is kept for a specified number of days. Archive has no conceptor support for versions. The user or Tivoli Storage Manager administrator isresponsible for determining what files get added to an archive.Recommendation: If archive is run multiple times against a file using the samearchive description, a new copy of the file will be added to the archive each timethat archive is run. To simplify retrieve, store only one copy of a file in eacharchive.Backups protect against file damage or loss that could occur through accidentaldeletion, corruption, disk crashes, and so forth. The server maintains one or morebackup versions for each file that you back up. Older versions are deleted asnewer versions are made. The number of backup versions the server maintains isset by your administrator.Note: If you frequently create archives for the same data, consider using instantarchives (backup sets) instead. Frequent archive operations can create a largeamount of metadata in the server database increasing database growth and80 IBM Tivoli Storage Manager for UNIX and Linux: Backup-Archive Clients Installation and User’s Guide
decreasing performance for operations such as expiration. See “Restoring data froma backupset” on page 130 for more information on how backup sets can begenerated and restored.Archive copies are saved for long-term storage. Your administrator can limit howlong archive copies are kept. The server can store an unlimited number of archiveversions of a file. Archives are useful if you need to go back to a particular versionof your files, or you want to delete a file from your workstation and retrieve it at alater time, if necessary. For example, you might need to save spreadsheets for taxpurposes, but because you are not using them, you do not want to leave them onyour workstation. See Chapter 6, “Archiving and retrieving your data,” on page143 for more information about archiving and retrieving files.Pre-backupconsiderations|LAN-free data movementAIX, HP-UX, Linux and Solaris (global zones and non-global zones) clients supportLAN-free data movement, which shifts the movement of client data from thecommunications network to a storage area network (SAN). This decreases the loadon the Tivoli Storage Manager server.The SAN provides a path that allows you to back up, restore, archive, and retrievedata to and from a SAN-attached storage device. Client data moves over the SANto the storage device via the Tivoli Storage Manager Storage Agent. The TivoliStorage Manager Storage Agent must be installed on the same system as the client.|||||||LAN-free prerequisitesTo enable LAN-free support, you must install and configure the Tivoli StorageManager Managed System for SAN Storage Agent on the client workstation. Formore information, refer to the following:v IBM Tivoli Storage Manager for AIX Storage Agent User’s Guide, SC32-0129v IBM Tivoli Storage Manager for HP-UX Storage Agent User’s Guide, SC32-0130v IBM Tivoli Storage Manager for Linux Storage Agent User’s Guide, SC32-0131v IBM Tivoli Storage Manager for Sun Solaris Storage Agent User’s Guide, SC32-0132The Tivoli Storage Manager Managed System for SAN Storage Agent anddocumentation, while contained on the client CD, is a separate product, andtherefore subject to the fees and licensing required by Tivoli and IBM.LAN-free optionsAfter installing and configuring the Tivoli Storage Manager Managed System forSAN feature on the client workstation, you can use the following options to enableLAN-free data movement:enablelanfreeSpecifies whether to enable an available LAN-free path to a SAN-attachedstorage device. See “Enablelanfree” on page 237 for more information.lanfreecommmethodSpecifies a communication protocol between the client and the Storage Agent.See “Lanfreecommmethod” on page 276 for more information.Chapter 4.
