Dumpcycle and runspercycle must both be considered. Amanda attempts to have at least one level 0 (full dump) of each DLE (DiskList Entry) each dumpcycle number of days or each number of runs per cycle. So if you have a dumpcycle == 10 days and only run amdump every other day (runspercycle == 5) then amanda checks each DLE to see if the last level 0 for that DLE was equal to or greater than 10 days earlier or 5 runs ago. Note, because of amanda's "dynamic scheduling", factors other than dumpcycle or runspercycle may cause a DLE to receive a level 0 earlier than its normal dumpcycle. For that DLE the hypothetical 10 day/5 run cycle starts over. -- Jon H. LaBadie [EMAIL PROTECTED] JG Computing 4455 Province Line Road (609) 252-0159 Princeton, NJ 08540-4322 (609) 683-7220 (fax)
