Hi, A slight variation of this theme is simple: For level 1+ backups "forget" inserting a tape. If you use "reserve 0" level 0 dumps will be postponed until a tape is ready. Amflush the level 1+ backups. You'll get two types of tapes in one configuration: The "level 1+" type and and a "mostly level 0" type. To the gurus: What happens if I play with chunksize and size of holding disks? Assume that level 1+ backups are guaranteed to be less than 2 GB and level 0 backups bigger. I could use a lot of holding disks of 2 GB each and set chunksize to 2.1 GB. So level 0 backups won't fit into any holding disk and need to go directly to tape, while level 1+ backups can be left on disk. This brings up a feature request: Removal of outdated backups from holding disk. Often you get this sequence of levels: 0z 1a 1z 2a 2b 2z 3a ... If you do the "forget" strategy and amflush "ALL" the non-z backups are skipped on amflush. It would save a lot of space on the holding disk. But it's not totally save. Making it an amadmin command might be the right way. On the other hand you could set bumpsize to 1 byte. Johannes Nie�
