Back Up Media in Library
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.
Use UNIX Utilities
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.
Use Both UNIX Utilities and AMASS Commands
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 “Practical Application” on
Page 3-156.
