Apple Tape Backup: Recovering Lost Data



I backed up my system using Apple Tape Backup then accidentally backed up
another smaller system on the same tape. Is there any way to recover the
remaining data from the first backup?

Since the volume information of the tape is stored at the beginning of the
tape, the original contents of the tape would have been lost when a new
directory was written on the tape. Something you might try is to use the
INIT Tape Disk that comes with the Tape Backup 40SC software. Mount the
cartridge as a streaming device on the desktop, then attempt to use a
recovery utility, such as SUM, to recover the lost files.
