Not on a per backup basis. But I have a look every few weeks and the
size of the archives vary - so worst case I'd be without it for a
couple of weeks if something failed. And there's precious little that
can fail - an rsync running as a cron job. It's worked for a couple of
years and if it breaks I catch it before too long. <br>
<br>
Ont thing that did fail way back when was I'd have the nightly backups
and the archives on the same partition. If I didn't clean up the
archives every month or so it would fill the partition. Then no more
backups. So now the archives and the backups go on different
partitions. So if the archive drive fills up, I lose whatever
snapshots happen before I catch it. But my nightly offsite backups
still work. And to make it a bit more robust, I put those two
partitions on two different physical drives. So nightly backups go to
physical drive A, partition 1. Then those backups get zipped and
archived on drive B partition 2. <br>
<br>
I like my system because it's reasonbly robust, handles backups and
archives, and was cheap and easy to setup. And it's automated.<br>

I've seen people finding out that the backup system had been failing for weeks when they needed it the most.

My office DB server sits in the back closet, I've
dropped a couple of
big drives into it. Every night at 3am my webserver and
desktops rsync
any changes over to the server to drive A. So I have a
snapshop of
last night. Then on the backup server after the rsync is
done I gzip
everything and copy that daily snapshot to drive B. Then
once every
couple of months I burn a couple of snapshots to a dvd and
clean up
drive B again.
Benefits:
- it's automated. and it's fairly fault
tolerant. If I forget to
clean up drive B I lose my daily archives but not my last
night's
backup. Easy to add another desktop into the process as
well.
Cons:
- It's not meant to be a bare metal easy restore.
I'm just backing up
data (/home directories and config files). And after
zipping I can fit
my entire operation on a DVD. I certainly don't have
anything
approaching 700gigs.
But first and foremost, when it comes to backups, remember
that HD
space is cheap cheap cheap, so use it liberally.

I thought I would ping the list to see what everybody else
is doing for
Backup and Recovery, both in terms of physical storage
(I've got 700GB
and growing) to software used.
I'm currently thinking about buying a few 2TB disks to
use as my
physical media and swap them every week, then something
like BackupPC,
rsync, or rdiff-backup to dump onto whatever disk is
currently mounted,
possibly giving me nightlies within that week.
For my Linux systems (read: important systems) restoration
from a hard
disk would be as simple as cp and grub-install from a
live-cd. What
about Windows and Mac OS? Are there any simple ways to
restore those
systems without having to fall back to restoring data on a
fresh
install? The Mac is my girlfriends primary work machine so
downtime for
reinstalling and re-licensing is rather undesirable.
The Windows machine is a toy for games, but reinstalling
everything on
that is such a pain that I'd like to make restorations
simple there too.
Ideally I'd like to spend as little as possible on
this, so things like
LTO-4 drives are out of the question.
