I'm looking to backup my Samba share onto an external FAT32 drive. Is there
a relatively simple way to do incremental backups? Basically if a file is
changed or added, I want the script to copy only the changed or added files
to an identical tree on the external drive.
A 'cp -R /mnt/samba /mnt/external' would do the trick, but it would waste a
lot of time overwriting unchanged files. Is there a 'copy if newer' flag?
man cp did not turn up any info on such a capability.
Thanks in advance
