Please advise what tool shall I use? TIA B.R. satimis

However, in the absence of such a thing, I would recommend you look into rsync, and just sync the USB directory to the home drive using a cronjob every night. It's not quite the same as what you're looking for, but it may be workable, depending on how how exactly you need it. __________________ DISTRO=Ubuntu Registered Linux User #388732

I am bzip-tarring the relevant directories now and later I will run a cron job to do differential backups based on the time of the last backup. Check through the manpage for tar. The specific option is -m or -modification-time. This is the same method that is generally used for tape backups. __________________ Registered Linux user #378740 New members read here / Forum Rules #linuxforums on irc.freenode.net

Hi bigtomrodney,

Tks for your advice.

I'm doing the same way as yours and burn the compressed tarball on DVD.

I'm reluctant to run incremental backup because the old files won't be deleted and replaced with the new file,

Still such arrangement does not satisfy me in case of HD failure. Because there are sitll some files missing.
