Hi, I am considering using bacula for my laboratory data backups. A few questions on whether it will work with my hardware, and regarding a few features:
1.Will my hardware work w/ bacula?
Tape Drive Cybernetics CY-8102 AIT2 8 mm tape drive, 50/150 GB, *** iSCSI ***
System Linux Redhat EL4, 2.6.xxxx kernel
2. How fast can bacula find a file on a tape to restore (i.e., does it fast-forward to the right spot on the tape, or does it "read" through at the regular [slow] read/write speed)? Can it restore a file from the end of the tape in a few minutes, instead of hours?
3. How are files written onto tape? Like (multiple) tar files, w/ filemarks. Or some other sort of format? In other words, can a bacula-written tape be recovered w/ tar (or some other standard, simple Linux utility) if needed?
I had purchased and was planning to use Cybernetics Accelerated File Access (CYAFA) software, which I had used before and had liked. Simple but fast.
And, CYAFA can fast-forward to the end of a tape, if that's where the file that you want to restore is located, in one or two minutes (!), unlike tar, which would take hours.
However, it turns out that CYAFA does not work with iSCSI, only direct SCSI. So, I have a choice of getting different software (bacula certainly looks very nice!), or swapping the tape drive out for a regular SCSI version (to Cybernetics credit, they'll do it for free) and then using CYAFA.
Thanks for answers and advice,
Dave
