I've been running amanda in a test environment, on a Solaris 8 machine, using GNU tar for backups. So far I am only backing up the amanda server itself. Everything seems to be working: the first night a level 0 backup took place on all the filesystems, followed by level 1 backups on subsequent nights. On each night, some filesystem gets promoted to a level 0 backup, but as I understand it this is by design to spread out tape usage.
What is odd is that it looks as though there is no difference between a level 0 and a level 1 backup. On the reports that are emailed each night, the same amount of data is written to tape for both the level 0 and the level 1 backup for all of the filesystems. I checked this by going through a table of contents for one of the level 1 backups, and it seems to be identical to a complete level 0 backup. Is this a side effect of using GNU tar instead of dump? Or is there some other reason why amanda is writing full backups but calling them level 1? Thanks, David Meissner
