I have just purchased an Dell (HP) 8 tape Ultrium autoloader. The tapes
I am using are all brand new and are marked as 100GB uncompressed
capacity, but I am only getting 45 to 60GB per tape, i.e. 45-60% of the
rated uncompressed capacity. My previous tape system was an AIT1
autoloader and I was getting 37 to 48 GB on a 35GB tape, i.e. 105-137%
of the rated uncompressed capacity. When I changed tape device all I
changed in the Bacula configuration files was the resource names and the
SCSI device names.
I am not specifying anything for Maximum/MinimumBlockSize and
MaximumVolume/Jobs/Files/Bytes and monitoring the device status while a
job is running I am getting Bytes/block=64,511.
I have scoured the documentation and Googled but am at a loss as to why
I am not getting more data on a tape.
Any suggestions?
Andrew
