- 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.
