The SAGE book on Backup and Recovery reports that Amanda does not support backups across multiple tapes for a particular file system. Is this still the case? We need to back up multi-terabyte file systems to LTO4, spanning many tapes. We do not expect a file to be larger than a tape, though we could imagine having this problem also. Does Amanda/Zmanda now support the notion of multivolume (in gnutar) or some similar method to span tapes? How are large backups handled?
