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. ... JG -- Joe Greco - sol.net Network Services - Milwaukee, WI - http://www.sol.net "We call it the 'one bite at the apple' rule.
