That would be a harsh rule to enforce. Suppose my small company backs up 7 desktop computers. If one DLE on the next tape was the last level 0, what should amanda do during that amdump? It can't "tape around" the problem dump file. Should it skip the dump leaving lots of new stuff not backed up? Go into degraded mode and hope the holding disk will hold all the forced incrementals? Copy the file from the tape to some archive area, hopefully with sufficient space. ??? IIRC, amcheck does give warnings about the impending situation. I'd say it is up to the admin to decide how to handle it. JL -- Jon H. LaBadie [email protected] JG Computing 12027 Creekbend Drive (703) 787-0884 Reston, VA 20194 (703) 787-0922 (fax)
