Hello,
If I am not mistaken, using the Amazon VTL (it isn't really tapes)
is documented in the Object Store white paper that is posted on
the
www.bacula.org web site. If it is documented there, it may
give you some additional insights.
In the beginning of 2018, I should be releasing a Bacula SD plugin
that writes directly to S3 compatible clouds.
Best regards,
Kern

Greetings…
Hopefully not a question that has been asked already
- my Google-Fu was failing me in the archives.
Our standard OS is FreeBSD and I’m trying to get the
director and storage working on a FreeBSD 11 machine using
Amazon VTL as the storage. Yeah, tapes - I know, but sometimes
I like the old ways.
Does anyone have this working that would be willing
to compare notes? I have it to the status of ‘almost but not
entirely working’ and trying to decide if it’s worth continuing
to try or just give up and install it on Linux.
Current issues:
FreeBSD iscsictl
randomly assignes device nodes on startup. Linux has UDEV to
address this issue. I’m not finding a corresponding feature
on FreeBSD. device.hints works for standard SCSI devices but
doesn’t appear to be an option for iscsi.
btape fails it’s write
test. The Amazon VTL drive appears to do what it should do
if I write files, EOF, etc. and reads/writes as I expect it
to. The btest rewinds tape, writes it’s 10,000 blocks, a EOF,
it’s 10,000 blocks and the EOF marker. Readback of the first
10000 succeeds normally and then it dies when it tries to read
an EOF (if I’m reading the source correctly). I don’t think
it should try to read an EOF but perhaps that’s not an error
on a physical drive.
Backup jobs succeed (at
least when not appending to existing tapes) and can be
restored until they cross a file boundary on the tape at which
point they fail, likely for the same reason as above.
I wasn’t having any luck
with MTX so I am using the rc-chio-changer script to move
tapes. The chio return function does not function - it
always gives ‘no source information’. Bacula expects that
command to work. I’m guessing this is a issue with the Amazon
tape changer emulation.
Worth continuing to fight with? Or give up on Beastie?
Thanks!
