Re: Which hardware for saving backups?

hello
I have a web server with about 270 GB of space on the three disks in
RAID5. It's only function is to host a Moodle e-learning system.
I would like to make an external backup of user/course files. Not just
for an extra level of redundancy, but also to protect the users from
their own errors.
I've read a lot about backup software and already decided about which
one to use. I would like you to ask about advice about hardware.
Is external USB disc suitable for this? Should I put an extra disc to my
workstation? Should I make an "dedicated" backup server out of an old
computer and new disc(s)? Should I try to buy some "ready-made" solution?
Since Moodle stores it's data in MySQL or PostgreSQL, you'll have to
backup the whole database. I wouldn't recommend using rsync.
How does *Moodle* suggest that you back up your data? If it has a
method for extracting/reloading specific courseware, that would make
it easier to recover a single teacher's mistakes.
How often do you think you need to backup the data? Do you
need/want to do off-site disaster protection or just protect against
user stupidity?
How often do you want to do the backups? Daily? Weekly?
If your data is compressible, a 750GB external drive (I like
Firewire enclosures) could hold 3 maybe 4 full database backups.
But restoring would be a time-consuming chore.
Going through a lot of hardship I could probably convince the faculty,
to invest into some storage solution, but since the server is one of the
only two Linuxes (Debians) on the faculty (the second one being my
workstation) I would like to offer them an interesting/cheap(er)
"OpenSource" solution.
How is hardware "open source"?
