All I wanted to say was that incrementals might easily grow very large because the files are large, so I think I would need a lot of extra tape to get useful data. (And adding capacity would not be worth the cost, since loosing the data isn't *that* critical.) But I might be wrong, or I could have incrementals for some of the directories where files are small and/or don't change very often, but I also thought that it would be a good idea to get the fulls right first, then start thinking about incrementals, but perhaps not... Anyhow, the original point was that I'm not running incrementals right now, so archival dumps would be exactly like the normal ones. > Be aware that amanda backs up "disklist entries", > either file systems or directory trees.

I think some way to split the entries across tapes would be *really* helpful, though. - Toralf
