I am using it for years now to backup (web/application/database)-server
data and configuration, is there any reason why I should not do so?
Databases can be a problem ...
Most of our application of BackupPC is for what you could describe as
"user data". Mainly things in home directories. But I tend to back
up /etc/ on everything with BackupPC, sometimes also /usr/local/etc/
and occasionally the odd subdirectory in /var/. People sometimes do
some pretty strange things in /opt/. The historical information for
files available from BackupPC can prove useful for almost anything.
For database *data* I don't let BackupPC get involved. The snapshot
utility for the database creates a file, and that file is transferred
by rsync, all from a crontab entry, to remote storage. The file won't
benefit from BackupPC's deduplication, and nobody wants an old copy of
a busy database so BackupPC's aged versions are no use either.
For similar reasons, mail server data likely won't benefit much from
the BackupPC approach. Web servers might - much will depend on the
design and application. Name servers will range from our tiny setups
with just a few domains to ISP setups with many millions, so each is
going to need to be studied as a special case, as I guess will most
other servers. We have a virus scanning server; we don't back it up,
since everything on it is downloaded from somewhere else. Of all our
servers it's probably the one most at risk. If it gets compromised
(it never has been) it would just be wiped and reinstalled.
... bootable image ... integrate that into backuppc ...
My head hurts. :)
