Failure to RTFM. Only the CHANGES, so incremental backup.

Sounds like a job for rsync!

Hi,

Why not setup software RAID?

hmm, software RAID isn't really a substitute for a backup solution. Or do you think of implementing RAID1, detaching the mirror and reattaching it once a day for syncing, then detaching it again?

FYI, RTFM is Read the f******** manual ;)

rsync is an excellent tool for incremental backups:

man rsync

for more info.

rsync -Cavz source destination

or even tunnelled via ssh (-e ssh) if the link is insecure, but as your drives are on the same system, the tunnelling is not necessary.

HTH:)   (Hope that helps)
