Loader are totally a love/hate relationship. They do make life a

work for you. Always look for the OEM rather than buying the name
brand equipment, they are most always the same HW and FW with a
different model number in it.
otoh, its hard to beat a 3 year warranty and on location support
from the same vendor as your server hardware, assuming your a brand
name shop in the first place.... hugely reduces finger pointing
when there's a complex issue to resolve. with OEM hardware bought
on the whitebox market, you're often faced with replace or
self-repair option at cost.
Having used a 20 tape library, and suffering through restores with
AIT2 tapes taking 10-12 hours per tape, I gave up on them. I went
with good old rsync, and built up a 4 TB system to handle backups.
Once configured, it's nearly a 100% hands off solution. You can read
about what I've done here: http://marks-tech-pages.blogspot.com
Works great especially for TBs of data that needs to be backed up
every day.
If you want something that stores the backups much more efficiently
(with a price in processing to do it), look at backuppc:
http://backuppc.sourceforge.net/
It compresses everything and hardlinks all duplicates so you can keep
about 10x what you'd expect online, and it has a nice web interface
for browsing the backups and doing restores.
Thanks Lee. I did look at backuppc before, and I didn't want anything that
compresses files, or used a web interface. Using rsync, it's a matter of scp
to restore, and that's it. I do use hardlinks to duplicate data, so my
storage requirements are kept as small as possible. Just about any CentOS
system can be configured to run backups in the manner I've written up,
nothing extra to install or learn. So, like most things, it boils down to
individual needs and expertise. I know for myself, tape backups just weren't
working well at all.
Backuppc can be configured to not compress, although I think the
filenames are still somewhat mangled and don't have their real
attributes so you can't access them directly. The web interface is also
optional and there are command line tools for everything you need. It
is handy to be able to download a single file or tar/zip archive
directly through a browser, though - and in the latest version you can
edit the configuration through the web interface.
