Well, what I'd recommend would depend a lot on on your tape changing
needs or the wish to not change tapes, the time to keep the backups, if
you want to create copies for offsite storage, and your backup windows,
for example.
I have tried using external hard disks, but I was not happy with
them. I was using external USB cases with IDE drives and the disks kept
crashing.
Thanks for tha confirmation :-)
My current strategy is to do a full backup at the beginning
of the month and an incremental backup each day in the month and then
recycle every 4 months. That way I always have 3 months of data backed
up. I would also like the flexibility for different kinds of backup,
for example I might in the future want to back the servers up to bare
metal recovery on a separate media.
Ok, I assume 400 GB per full backup run, and less than 100 GB
incrementals per month.
Bacula seems to be able to handle all of my requirements, and now I am
looking for the hardware. Does anybody have recommendations, what to
use, what not to use etc...
Concerning tape technology:
One possible solution would be a Quantum SuperLoader3 with a LTO-2
drive, a cheaper possibility the SL3 with DLT-V4 (quite new, and
definitely low end), a high performance device could use an SDLT or
LTO-3 drive. Other manufacturers offer similar devices.
I know that there are people out there using helical scan stuff like DDS
(don't!) or AIT or the VXA drives, but I kind of prefer linear
recording. Might be a matter of taste, though.
Bottom line: Don't use DAT, don't use a single drive when you know that
one cartridge is not enough for a full backup, and don't buy the
cheapest device you can find. Also keep in mind that extended warranty
and support is probably worth their money when you handle important data.
Disk based backups:
Use a good, high-capacity, NAS or SAN appliance. Keep spare disks close
to where you need them. Make sure your device can alert you of predicted
problems reliably, and has the tools to manage replacement ad hot spare
disks easily.
Need an offer? ;-)
