tar zcvf today.tgz `find /etc /home -mtime -7 ( -type f -o -type l ) -print
scp today.tgz ftp-backup:/pub/Backups
- add your host key for passwd-less backups
- or -
no passwd needed
mount ftp-backup:/pub/Backups /mnt/Backups
scp today.tgz /mnt/Backups
sync ; umount /mnt/Backups
dozens of free backup scripts

because rsync doesn't keep a copy of the last set of changes
before it overwrite it ??
( you do NOT know what day foo.c in the backups got overwritten
( by the latest changes because you only have one file in backups
- good backups depends also on how you implement it and
is it for backups and restore the last copy you had
or to go back in history to see who and when foo.c was changed
( you can also use cvs to do the same, but the whole cvs needs to
( be backed up too
- a good backup policy will keep multiple copies of the same files
- yesterday
- last week
- last month
- incremental and full backups
and your backup policy should survive a 100% disk full and
you do NOT lose data, because how often do you check the
backups is working ..
- and rotate each on some schedule to remove old backup junk
- when you find out you need foo.c from backups, you
might have to search back 1 or 5 or 10 previous versions
to find the one that is un-corrupted or un-hacked
