We've been using bacula for several months to backup a few terabytes
to Super AIT-1. We just upgraded our backup server to actually be able
to keep up with the data rates the drives support so I figure now is a
good time to actually mention that, yes, it does work with this Qualstar
monstrosity.
The changer is a Qualstar 5466 with two Sony SDZ-100 Super AIT-1
drives and 66 slots and a bar code reader attached via SCSI. Everything
works out of the box with Linux 2.4 & 2.6 using the standard SCSI tape
drivers. The only trouble I've had using it with Bacula is that I
initially set it to use 512k blocks and there was a hidden "sanity"
limit of 500k in the SD that caused it to barf when trying to read the
tapes for restores. I patched my local version to move the limit to
512k and all is happy. Somebody should probably add this to the
known-good configuration lists.
I'm using PostgreSQL for the catalog after trying sqlite and mysql,
both of which seemed to get really bogged down as the catalog grew to
it's current ridiculous proportions of 5.3G
Below is the report of the latest job run on the new Dual Opteron
backup server running Debian/sid amd64 (64bit mode). The File Daemon on
the client was the limiting factor on the speed, but it was clearing
30M/s of network traffic for sustained periods. At that data rate the
backup server still had some room to push more data. I'll try running a
simultaneous dump to both drives this weekend and see now it holds up
Thanks for the great product.
