Hello,
Iam trying to setup bacula as below :
OS = SLES 9 with SP3, 4GB memory, 8 GB Swap.
Version bacula = 2.2.7
Tape Library = Fujitsu Siemens TX48.Autochanger with 48 slots.
Media = LTO -3.
When iam trying to write to the tape drive. The speed is very slow like
Transfer rate = 7.673 M bytes/second ( This is the nearly native speed of the
tape drive )
I enabled the Hardware compression as given by document, but eventhough the
speed is 7.673 M bytes/second exactly.
When i use a dump with compression and 1024 Block size, it writes at very good
speed as below:
dump -0 -b 1024 -f /dev/nst0 /var
DUMP: Date of this level 0 dump: Mon Feb 18 16:45:24 2008
DUMP: Dumping /dev/mapper/system-SYSTEM_VAR (/var) to /dev/nst0
DUMP: Label: none
DUMP: Writing 1024 Kilobyte records
DUMP: mapping (Pass I) [regular files]
DUMP: mapping (Pass II) [directories]
DUMP: estimated 157674 blocks.
DUMP: Volume 1 started with block 1 at: Mon Feb 18 16:45:32 2008
DUMP: dumping (Pass III) [directories]
DUMP: 0.65% done, finished in 0:00
DUMP: dumping (Pass IV) [regular files]
DUMP: Closing /dev/nst0
DUMP: Volume 1 completed at: Mon Feb 18 16:45:40 2008
DUMP: Volume 1 154624 blocks (151.00MB)
DUMP: Volume 1 took 0:00:08
DUMP: Volume 1 transfer rate: 19328 kB/s
DUMP: 154624 blocks (151.00MB) on 1 volume(s)
DUMP: finished in 6 seconds, throughput 25770 kBytes/sec
DUMP: Date of this level 0 dump: Mon Feb 18 16:45:24 2008
DUMP: Date this dump completed: Mon Feb 18 16:45:40 2008
DUMP: Average transfer rate: 19328 kB/s
DUMP: DUMP IS DONE
But the writing speed with and without Hardware compressiong is exactly 7.673
M bytes/second .can someone please help me. Am i wrong in any configuration.
Thanks and Regards / Mit freundlichen Grüßen,
