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

Tivoli Storage Manager looks for files only in the /home file space, the/home/monnett file space, or the /home/monnett/project1 file space, depending onwhich form you use.Special file systemsSpecial file systems contain dynamic information generated by the operatingsystem; they contain no data or files. The Tivoli Storage Manager client ignoresspecial file systems and their contents.Special file systems include the following:v the /proc file system on most of the UNIX platformsv the /dev/fd file system on Solarisv the /dev/pts on LinuxNFS or virtual mount pointsWhen files are backed up and archived from a file system or virtual mount point,Tivoli Storage Manager does not follow the nested NFS or virtual mount points (ifany are defined on a file system). The nested NFS or virtual mount points will notbe backed up or archived.Management classesTivoli Storage Manager uses management classes to determine how to manageyour backups on the server. Every time you back up a file, the file is assigned amanagement class. The management class used is either a default selected for you,or one assigned to the file by an Authorized User with an include option in theinclude-exclude options list. The selected management class must contain a backupcopy group in order for the file to be backed up.Select Utilities → View Policy Information from the Java or Web client GUI toview the backup policies defined by the Tivoli Storage Manager server for yourclient node.Related conceptsChapter 9, “Understanding storage management policies,” on page 229Storage management policies are rules your administrator defines in order tomanage your backups and archives on the server. Your data is associated (orbound) to these policies; then when the data is backed up or archived, it ismanaged according to policy criteria. Policy criteria include a policy domain, apolicy set, a management class, and a copy group.Symbolic linksTivoli Storage Manager handles symbolic links differently than it does regular filesand directories. How the client handles symbolic links depends on options settings,whether the target directory is accessible, and the way you specify objects.Note: Symbolic link processing as described here does not apply to Mac OS X.Symbolic links are always backed up as files and are never followed.A UNIX symbolic link is a file that contains a pointer to another file or directory.The object the symbolic link points to is called the target object.A symbolic link can be backed up as path information to a target directory, or itcan be backed up as a directory. If the symbolic link is backed up as a directory,the files and folders in the target directory can be backed up as well. What youChapter 4. Backing up your data 159
