Questions: How can I get all 33.9 GB of data on my 40GB tape media? How can I get as much data as possible on first tape before moving to second tape? Hello, Summary or problem is as follows, -OS: Solaris 9
-Version #: AMANDA 2.5.1p2 -TapeInfo: Quantum DLT4000, 40GB Native, 80GB, -Driver Info: /dev/rmt/0n (no hardware compression) -Problem: I have 33.9 GB of comressed data spread accoss 14 different partitions that are scheduled for backup to tape at level 0 weekly. After software compression, each partition dump size range between 2.3MB and 7.8GB. The problem is that I getting a lot of wasted space on the tape writes. Runtapes in amanda.conf = 2. The first fills up to only 33.4% and then AMANDA moves job to a second tape filling up to 45.6%. In previous backups a ?ran out of tape? error appeared after using both tapes at under 50% and I would be forced to do a amflushed the next morning to a 3rd tape. Detail of Settings in amanda.conf: inparallel 4 dumporder "sSsS" taperalgo firstfit runtapes 2 tpchanger "chg-zd-mtx" tapedev "/dev/rmt/0n" tapetype QUANTUM-DLT4000 define tapetype QUANTUM-DLT4000 { comment "Quantum DLT4000 (hardware compression disabled)" length 39936 mbytes filemark 4 kbytes speed 1008 kps } define dumptype comp-root-tar { root-tar comment "Root partitions with compression" compress client fast
