Question for tape backup

[Edson Noboru Yamada]

Some points to consider:

a) A tape library can dramatically reduce your workload and chances of
errors.

b) Software: there are some good open source solutions (amanda, bacula). Not
as good as Veritas netbackup, for example, but they´re work fine (specially
for
a non large number of clients, as seems your case).

c) Disk backups have a quicker restore. They´re good for recent backup
images (that
are more likely to be restored).

hope this helps
