Will,
Very sorry for you. Very glad I've never had to suffer the fire offense.
That said I tar up all of the source code for my stock trading
strategies and scp them to a machine in another state 3 times a week.
I've got 50GB of data off site at this point. As I'm in California and
scheduled to sink into the Pacific in 2012 I figured anything west of
the San Andreas fault wasn't a good idea...
I was burglarized once. They took my 1937 Gibson Super 400 and a
Gibson RD Artist. Those, unfortunately, are very had to back up...

copy of your really important stuff off-site.

+++++ actual physical backups.
No disk system is enough. Not journals on single disks. Not RAID. Not
RAID with journals. Backups are key, and maybe MORE important than
backups is actually testing that restoring from backups actually
works. It's good to keep one junkie old computer around and make sure
that backups can be restored on a machine that's never seen them. In
the last 15 or 20 years I've lost 3 machines to catastrophic failure.
Making sure I had restorable backups was key to the data I saved and
key to the data I lost.
RAID for dummies like me cannot get much easier than mdadm.
- Mark > True, but how do you backup your stuff?
Oh, I don't. :-) When using plain ext2/3/4 file systems you
receive hints (strange pauses, eventually a random file is
corrupted) that something is wrong long before everything is lost.
I've never lost anything important, but have replaced
my HD many times.
I think you are very lucky :)
Few month ago my mediacenter broke the HD (ext3) and without backups i
lost serveral Gig of data :(
Now I use a RAID1 and it saved me once (because power supply problem in
1 of the disk).
And now is simple tu install a software raid in a Linux box.
Another situation where (incremental) backup is important is when you
make a change of a project and you want to return to previous version.
So I think RAID1 + backup is the best choice :)
