[olug] Backup software

[Trent Melcher]

I agree with Nick, also remember hard drives keep getting cheaper , so with
the cost per MB or GB these days and the speed of hard drives, I would
recommend having a secondary backup going to a backup server full or hard
drives.  That is what I do,  I have a backup server, (RH 7.2 Box) with 4 -
80 GB drives in them, depending on the platform we are backing up, we use a
combination of tar, dd, cpio, and dump.  We do all our backups do disk first
on the backup server, then we have our operators  dump those backups to
tape.  The cool thing is all the backups are kicked off from the cron on the
backup server, and the operator on-call for the week gets emails after every
backup with a status ( completed, or which filesystem had a problem, etc.)

On the topic of backups, I recommend doing full backups on a daily basis if
the tape drive has the capacity and the backup overhead doesn't interfere
with normal operations.  I'd also recommend a full image backup at least
once every few months.

By image backup I mean something along the lines of a dd of all of the
internal storage.  An image backup can restore everything including
partition tables and so forth.  There is a nice free product called Mondo
for doing this if you aren't comfortable with doing it manually.

Daily backups can be done with tar or cpio.  Either one will do the job so
just use the one you have a higher comfort level with.  If the data is super
critical I would advocate doing a second backup each day of just the
critical data.  Tapes delight in failling just when you need them so having
a second recent copy of anything important is important.

Always remember the golden rule of backups.  No matter how many tapes you
churn out you don't have a real backup until you've tested a restoration to
validate your backup methods.

What does everyone recommend as a backup solution on a single server with an
internal 40/80GB DLT drive?  I want to do daily backups and be able to
access the server remotely to do restores if need be.  Remotely could be SSH
or the program itself.

Thanx for any and all help!!!
