When I was working at the University of California San Francisco,
I made some simple modifications to tar for use as a backup facility.
As far as I know, this is still the method being used for backup on
that system.

The changes I made were:

	o Incremental mode (accepts file names from standard input
		and directories don't recurse).
	o Stay on the device associated with a disk or directory
		(don't cross mount points).
	o Multi-volume tapes on drives that support EOT reporting
		(I added a simple ioctl to our tape driver that
		reported EOT status).
	o A flag for continuing after directory checksum errors (to
		allow starting with any volume in a multi-volume
		set; it quickly syncs up on the first valid header).
	o Copies of all errors could be sent to a log file for
		semi-unattended operation.
