Info

v The Solaris backup-archive client does not support the combination of QFSand SAM needed to archive files onto tertiary background storage, such astapes. Instead, it recalls files from tape to disk automatically if it findsmigrated files during a backup.v A QFS file system contains two hidden system files and a system directorythat cannot be backed up. This is acceptable because a backup of these filesis not needed. They contain internal data to manage the file system. Thisdata will be automatically excluded from a backup and recreatedautomatically by the file system itself if a restore of files in that file system isinvoked.5. Incremental, selective, filelist back up, archive, restore, and retrieve processingof the Veritas file system and its ACLs on AIX are supported. Restore of aVeritas volume on a Logical Volume Manager volume and vice-versa is allowedprovided both have the same file system type.Attention: If you are running GPFS for AIX or GPFS for Linux x86/x86_64 in amulti-node cluster, and all nodes share a mounted GPFS file system, Tivoli StorageManager processes this file system as a local file system. Tivoli Storage Managerbacks up the file system on each node during an incremental backup. To avoidthis, you can do one of the following:v Explicitly configure the domain statement in the client user options file(dsm.opt) to list the file systems you want that node to back up.v Set the exclude.fs option in dsm.sys to exclude the GPFS file system from backupservices.Maximum file size for operationsTable 31 specifies the maximum file sizes for the native file systems on TivoliStorage Manager UNIX and Linux client platforms.Note: The maximum file size depends on the type of a file system. The TivoliStorage Manager client does not check any file size limit during backup, archive,restore, or retrieve operations. As long as the file system allows creation of the file,the Tivoli Storage Manager client will back up or archive the file.Table 31. Maximum file sizePlatform Max file size (in bytes)AIX 5.2 and 5.3 (GPFS) 109,951,162,777,600 (100 TB)AIX 5.2 and 5.3 (JFS2) 1,099,511,627,264 (1TB - 512)HP-UX 1,099,511,627,775 (1TB-1)All Linux clients 9,223,372,036,854,775,807 (8EB-1)UNIX 4,294,967,295 (4GB)Solaris 1,099,511,627,775 (1TB-1)|||||How Tivoli Storage Manager handles long user and groupnamesTivoli Storage Manager can handle user and group names that are up to 64characters without any issues. However, names longer than 64 characters requirespecial handling by Tivoli Storage Manager.86 IBM Tivoli Storage Manager for UNIX and Linux: Backup-Archive Clients Installation and User’s Guide
|||||||||||||Recommendation: Do not exceed the 64 character limit for user and group names.If you do, Tivoli Storage Manager will shorten the name to fall within this limit byusing the following transformation: Take the first 53 characters, append a /, andthen the numeric id as a character string.An error message will be logged containing both the long name and the resultingshortened string. For most functions, you do not need to be aware of the shortenedname. The exceptions are:v The set access commandv The fromowner optionv The users and groups (authorization) optionsIn each of these cases, when you need to enter a name, you will either have to findthe error message containing the transformation, or construct the name using theabove outlined rule.Performing an incremental, selective, or incremental-by-date backupYour administrator might have set up schedules to automatically back up files onyour workstation. See Chapter 7, “Automating tasks,” on page 151 for informationon checking and running the schedules available to you. The following sectionsdiscuss how to back up files without using a schedule.There are two types of incremental backup: full incremental and partialincremental.Full and partial incremental backupIf you select entire file systems, you are performing a full incremental backup. Ifyou select a directory tree or individual files, you are performing a partialincremental backup.The first time you run a full incremental backup, Tivoli Storage Manager backs upall the files and directories on the file systems you specify. This process can take along time if the number of files is large, or if one or more very large files must bebacked up. Subsequent full incremental backups will only back up new andchanged files. This allows the backup server to maintain current versions of yourfiles, without having to waste time or space by backing up files that already existin server storage.Depending on your storage management policies, the server might keep more thanone version of your files in storage. The most recently backed up files are activebackup versions. Older copies of your backed up files are inactive versions.However, if you delete a file from your workstation, the next full incrementalbackup will cause the active backup version of the file to become inactive. If youneed to restore a file you have deleted, and if a full incremental backup has beenrun since you deleted the file, then you will need to restore an inactive version ofthe file (assuming that a version still exists on the server). The number of inactiveversions maintained by the server and how long they are retained is governed bythe management policies defined by your server administrator. The purpose of theactive versions is to represent which files existed on your file system at the time ofthe backup. See Chapter 8, “Understanding storage management policies,” on page157 for more information about storage management policies.To perform a full or partial incremental backup using the client Java GUI, selectthe Incremental (complete) option from the pull-down menu at the top of theChapter 4.
