Hi There Yesterday I got a HP T20 10/20GB, travan 5, SCSI tapedrive. Using bacula at work for doing a lot of bacups I installed bacula at home and immediatly took my new toy out for a ride with bacula at the steering wheel. ...
... I was greatly dissapointed: ~100kb/s. And a lot of shoeshining I then made a spoolarea of 100MB and tried to take a backup of the same 3GB data. ... I was greatly dissapointed: ~100kb/s. And a lot of shoeshining Hmm, I then read a lot about the HP surestore T20. Seems unclear why HP have put their brand on this crap. Only 512 byte blocksize, no buffering, no nothing apparently. Then tried to do a tar cf /home/maibritt /dev/nst0 (~400MB). G ... I was pleasntly supprised: ~630kb/s but could here some shoeshining. I then put the buffer application into the loop www:/home# mt -f /dev/nst0 rewind www:/home# tar cf - maibritt/ | buffer -z 10240 > /dev/nst0 424670K, 677K/s www:/home# mt -f /dev/nst0 rewind www:/home# tar cf - maibritt/ | buffer -z 102400 > /dev/nst0 424670K, 943K/s www:/home# mt -f /dev/nst0 rewind www:/home# tar cf - maibritt/ | buffer -z 204800 > /dev/nst0 424670K, 946K/s .. and hardly any shoeshining from 102400+ onwards. This is near the theoretical 1024K/s that HP claims the drive can do. So back to bacula. What is limiting bacula in getting around 900K/s? How are my chances of using bacula instead of the barebone solution with this piece of junk? And if it can be done, what needs to be done in order to achieve reasonable speeds with this drive?
