There are a variety of ways to back up the data residing in the 
library. Even though a library is involved, the backup issues are 
fundamentally the same as for hard disks. The main difference 
is the amount of data contained in the library.

The solution depends on the available system resources and the 
backup requirements of your specific environment. The correct 
solution could even be a combination of the methods described 
below. For that reason, a step-by-step procedure is not included 
here. Three ways of backing up media are described below.

One solution is to use conventional UNIX backup utilities for 
your media.

The practicality of doing this depends on the amount of data 
being written and the overall size of the library. Performing a 
full backup against a large library takes a long time so 
incremental backups may be appropriate.

Another way to back up the media is to use AMASS commands 
and UNIX utilities to generate a sorted list of files contained on 
each volume in the library. Then, the sorted list can be directed 
to a backup. An example of using the 

volfilelist

 command 

to do this is described under 

.
