Acronis "True Image" is the name of he product:
I spoke with their devs about it back in 2005ish.. It's a kernel level wedge
to kind of do what LVM copy on write does for backups.. Appears to be a nice
turn-key/commercial solution with full, incrimentals, diffs, etc.
For my desktop at work.. I start off with a cold-clone by booting off an usb
stick and cloning drive a to drive b:
# cat /dev/sda > /dev/sdb
(much faster than dd)
and then boot the system.. mount the target drive and use rsync nightly from
my /home/ locations.. with an occasional/manual resynching of /.
Works like a charm..
Of course.. many Rackers jusrt use JungleDisk and backup to the cloud. That's
cool (and easy) too.
