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
