Re[2]: backing up more then one instance

How about backing up to disk and then tar/cpio/etc to tape? It's expensive in disk but it works. Or you could do the largest instance over night to tape. The smaller to disk. And then tar the smaller during the day after the tape is changed.

You could use a no-rewind device and consecutively write the second archive to the second file on the tape but ontape will not be able to restore the second archive since it rewinds the tape twice during the restore. You would have to manually copy the file off of the tape to another device. Not fun and I've never tried this myself. Art S. Kagel
