[kbaggen]

Hi there,
wich to make a backup of some of my files stored on 500 GB sata1 on my Segate Goflex net to 320GB sata2, so what program should I use?

Would love some hit here!

Rsync to copy the files and cron to schedule it.
Rsync has options to copy only files that are newer than the target.

agreed rsync is the best.

rsync -avP /mnt/sata1 /mnt/sata2 --delete --progress

you can also get more sophisticated and have it do incremental backups for each day, using hardlinks for files that have not changed, so it uses the minimum space.

--delete will delete files on sata2 that no longer exist on sata1
