Specifying Which Data Is Backed Up

The Save Set attribute of the Clients resource specifies the data to be backed up for the client machine. You can specify more than one save set in the Clients resource. The Backup server starts a new instance of the client's save program for each save set you specify.

What Is a Save Set?

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).

Use of Unique Client/Save Set Combinations

You can use one client license on a machine, but back up different portions of its data at different times. This is useful if a client has a large volume of data. You schedule the client machine backup as several, separate client/save set backups. When you redefine a large filesystem into multiple client/save set instances, you automatically back up a large client filesystem and balance the system load by avoiding a full backup of the entire filesystem at one time.
