Multiple-Tape Catalog Backups

The basic concept behind the protection of large NetBackup catalogs is
to split the

catalog-backup process into two steps:

1. Back up the majority of the data from the images subdirectory on the
master server.

2. Back up a small sub-set of the images subdirectory, together with the
remainder of the

NetBackup and Media Manager catalog files and directories from the
master and

media servers.

Since the first backup contains the majority of the data, it must be
able to span tapes. This

is achieved by using a normal NetBackup job to back up the data. As a
result of this

normal backup, an entry is placed in the images subdirectory tree for
the master server.

This catalog entry allows the user to browse the catalog for files
during a restore

operation.

The second backup must back up the portion of the images subdirectory
that contains the

catalog entries for the master server, together with the other parts of
the NetBackup and

Media Manager catalogs. Since this is a relatively small amount of data,
it fits onto a single

tape. It must also be possible to recover this backup without the
NetBackup catalogs being

available. This is achieved by using the normal NetBackup catalog-backup
mechanism to

perform the backups.

Our Production backup environment has grown tremendously in the last six
months and our catalog backup has gone from running a little over an
hour to 4 hours.  We are backing up on average around 4TB per day.  I'm
curious to know what other options there are to getting my catalog
backups to run in less time.  This 4 hours is eating away my NetBackup
maintenance window that I like to have.  Any suggestions would be
greatly appreciated.
