Yes (but it's a common mistake). The 'dumpcycle' parameter tells amanda the longest amount of time you want between 2 level 0 (full) backups of any particular disklist entry. 'runspercycle' tells amanda how many times per 'dumpcycle' you're going to run amdump. Amanda uses these parameters to schedule full and incremental backups of every disklist entry *with the goal of equalizing tape usage each night*. To achieve this, amanda spreads the level 0s out over the length of the dumpcycle. > Also, I saw no mention of the levels for the dumps in the man page for > Amanda. Where can I find more information about these levels? The levels are described in the man pages of the backup tools (tar or dump), since those are what are actually doing the backups. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
