This looks like a bad tape. I'm new to Bacula. Can I get a second opinion, please?
Here is some info about my setup: Debian GNU/Linux, kernel 3.0.0-2-amd64. Debian packaged Bacula version 5.0.3-1+b1. This is a Quantum DLT S4 drive attached to an LSI20320-R card on a PCI 32bit bus slot, Gigabyte GA-MA78G-DS3H desktop motherboard. The hardware has been in use for a few years and is stable. The thing is, tar isn't having this problem with the tape in question. Yes I restored and compared all of the files. The backup fileset was the same. Quantum also has a nice toolset called xTalk and I have run extensive read/write tests against the tape and a 23-minute long "device health check" which did not indicate any kind of error. Below are three separate backup attempts on a fairly small set of data. You will see the Bacula log info, and then the kernel log info. This is the same tape. When I tried another tape, the backup succeeded without the error. Note that /var/log was included, so the file set size changed(probably grew) slightly between attempts. It looks like the error happens when Bacula is trying to write the end of tape. 26-Nov 00:05 parts-sd JobId 28: Error: block.c:577 Write error at 1:22939 on device "DLT-S4-1" (/dev/nst0).
