Save sets are groups of files from a single client machine to be backed up by Backup. A save set can include any of the following:
All the files or filesystems on a client. This is the default condition indicated by the value All.
A filesystem, for example, /usr.
A single file, for example /home/mars/stars.txt.
A raw space, such as a logical volume.
A database (if you have a Solstice Database Module installed).
