Info

Tivoli Storage Manager can restore your home directory if you are not logged in.This means that you cannot restore your own home directory. Your homedirectories can be restored by the system administrator.Create a second system administrator account so that the primary systemadministrator account can be restored.Mac OS X Time Machine backup diskTime Machine is the backup application available with Mac OS X 10.5.Tivoli Storage Manager can be used at the same time as Mac OS X Time Machine.However, due to the unique nature of how the Mac OS X Time Machine backs updata, you should consider the following items before using Tivoli Storage Managerto back up the Mac OS X Time Machine data.vvvThe Mac OS X Time Machine backup disk makes extensive use of both file anddirectory hard links to minimize disk usage.For example, if the disk backed up with the Mac OS X Time Machine is 5 GB,the first backup copies all 5 GB of data to the Mac OS X Time Machine backupdisk.Subsequent backups only copy the files that have changed since the previousbackup. All files and directories that have not changed will be hard linked withthe version copied over during the previous backup.The Finder shows each backup as 5 GB, for a total size of 10 GB. However,because of the use of hard links, the total disk usage will only be slightly largerthan 5 GB.Due to how Tivoli Storage Manager handles hard linked data, it backs up allhard linked objects that are not already on the Tivoli Storage Manager Server.For example, 10 GB of data would be sent to the Tivoli Storage Manager server.When files are restored that are hard linked, Tivoli Storage Manager recreatesthe original hard link. This can only be done if all files that are hard linked arerestored at the same time. This is not practical for a large Mac OS X TimeMachine backup disk.When the Mac OS X Time Machine copies files to the backup disk, ACLs areadded to the files to protect them from deletion.Tivoli Storage Manager can back up and restore files with ACLs. However, anyfiles that are restored would still have these restrictive ACLs in place.Tip: Due to how Tivoli Storage Manager handles the Mac OS X Time Machine backup data, exclude the Time Machine back up data. All Time Machine data is in adirectory named Backups.backupdb.118 IBM Tivoli Storage Manager for UNIX and Linux Backup-Archive Clients Version 6.1: Installation and User’s Guide
Related concepts“Excluding system files” on page 84There are some recommended system file excludes that should be placed in theclient options file. These system files are either locked by the operating system orthey can cause problems during restore. These are system files that cannot berecovered without possibly corrupting the operating system, or temporary fileswith data that you can easily recreate.Performing an incremental, selective, or incremental-by-date backup(UNIX and Linux)Your administrator might have set up schedules to automatically back up files onyour workstation. The following sections discuss how to back up files withoutusing a schedule.There are two types of incremental backup: full incremental and partialincremental.Related tasks“Setting the client scheduler process to run as a background task and startautomatically at boot time” on page 214You can configure the Tivoli Storage Manager client scheduler to run as abackground system task which starts automatically when your system is started.This is true for both client acceptor daemon-managed and traditional methods ofrunning the Tivoli Storage Manager client scheduler.Full and partial incremental backupAn incremental backup backs up only new and changed files. Whether youperform a full or partial incremental backup depends on what you select forbackup.If 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 that you specify. This process can take a long time if thenumber of files is large, or if one or more very large files must be backed up.Subsequent full incremental backups will only back up new and changed files.This allows the backup server to maintain current versions of your files, withouthaving to waste time or space by backing up files that already exist in serverstorage.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.Chapter 4. Backing up your data 119
