IBM Tivoli Storage Manager for UNIX and Linux Backup-Archive ...

estore depends on how the symbolic link was backed up, the scope of the restore,the setting of the followsymbolic option, and whether the target directory isaccessible at the time of restore.Related reference“Archsymlinkasfile” on page 266The archsymlinkasfile option specifies whether Tivoli Storage Manager follows asymbolic link and archives the file or directory to which it points, or archives thesymbolic link only. Use this option with the archive command.“Followsymbolic” on page 320During a backup operation, the followsymbolic option specifies whether you wantto use a symbolic link as a virtual mount point. During a restore or retrieveoperation, the followsymbolic option specifies how the Tivoli Storage Managerclient restores a directory whose name matches a symbolic link on the restoretarget file system.“Virtualmountpoint” on page 431Authorized User: The virtualmountpoint option defines a virtual mount point for afile system if you want to consider files for backup that begin with a specificdirectory within that file system.Incremental or selective backup of symbolic linksHow the client backs up a symbolic link depends on whether the target of thesymbolic link is a file or a directory, and how you specify the symbolic link on theincremental or selective backup command.If a symbolic link points to a file, the client only backs up the path information.The client does not back up a file that is the target of a symbolic link.If a symbolic link points to a directory, the backup depends on how the directoryis specified on the command.If a directory is specified with a trailing slash on a selective or incremental backupcommand, the client saves the symbolic link as a directory, and backs up thecontents of the target directory.If the symbolic link is entered without a trailing slash, or if a symbolic link is notexplicitly stated in a backup file specification, the client backs up only the pathinformation to the target directory. The contents of the target directory are notbacked up.In the examples below, assume that symdir is a symbolic link to target directory/fs1/guest/. /fs1/guest/ contains these objects:/fs1/guest/file (a file)/fs1/guest/dir1 (a directory)/fs1/guest/dir1/file1 (a file)Example 1dsmc incr /home/gillis/symdir/In this example, the client backs up the symbolic link as a directory, and backs upthe contents of the target directory /fs1/guest/. Ifsubdir=yes, the client backs upsubdirectories of /fs1/guest/.Example 2adsmc incr /home/gillis/symdir/dir1160 IBM Tivoli Storage Manager for UNIX and Linux Backup-Archive Clients Version 6.1: Installation and User’s Guide
