I've been lamenting for some time that my VXA1 tape drive, with its 33GB native (i.e, uncompressed) capacity and 3MB/s transfer rate that seemed so huge and fast when I got it, is no longer really big enough or fast enough for my needs, especially now that minbar just got its disk array upgraded to almost 400GB of RAID5. By chance, I happened to mention this to one of the other Bacula developers late last night.
As a result of this chance mention, I 've been offered a free LTO1 external tape drive. He just had it sitting around not doing anything with it. (For those not familiar with LTO, that's 100GB native capacity and 15MB/s transfer rate.)
Ask, and sometimes, ye shall receive.
