Hi
If you don't back up the database(s) then the last good backup may fall off
the tape cycle. If you chose to do this then restoring the database(s) will
you having to search more tapes for the relevant backups.
If the backups don't fit onto a single tape then you may wish to use an
autochanger (if you aren't already!). It might be possible that you could
use a server that can stage the backups on disc before putting to tape at a
different time. You may also want to consider separating database backups
from other types of backups to speed up the time needed to recover.
You may want to remove the sample databases like northwind and pubs from
your live systems, they are re-creatable from the scripts which are
downloadable if necessary.
If databases are not updated or not updated in an ad-hoc way, then you may
wish to make them read-only and use a different backup cycle for them.
