Very good point.
For my laptops, nearline field storage includes my laptop's drive and a
portable external drive. Online and nearline home storage is a network
attached storage array running proprietary X-RAID (like RAID-5) with a
hot-spare drive. All my machines (desktops, servers and laptops) are set
to perform regular backups to the NAS. Offline backups are done to a
series of external USB HDs that are rotated into place for nightly
incremental and weekly full backups. Current retention schema is 4 weeks
of backups with a one week offsite physical rotation (performed monthly
to a safety deposit box). I'm at the moment trying to figure out a good
way for doing streaming backups to an offsite DC.
We used to use DVD's for off-site backup, but that's not been the best
of solutions. I've been experimenting with external hard drives but
I am less comfortable with them; I've seen too many drives fail. The
idea of letting them sit for awhile and praying they spin up later
bothers me. :-) On the other hand, running Unison to a server someplace
else has obvious benefits and some downsides too. Backups remain a
tricky problem to get right.
