BRU PE spending a very long time in "Writing catalog to tape ..." mode.
on Jun 17, 2018 at 5:29:11 am

I just ran a backup of 1.48Tb on macOS 10.13.3 using BRU PE 3.2.3 (52) to LTO-6 tape.

It appears that the backup took just under 5 hours, but as far as I can tell the GUI has been sitting there for an additional 11 hours waiting for "Writing catalog to tape ... " to finish, and verify has not begun.

I guess the lack of obvious console messages is my penance for using a UI rather than doing things from the command line (where feedback is generally immediate and useful). I've attached a screenshot to this message, the GUI shows that the backup finished 04:51:52 after it began, but the verify hasn't happened, "Total Elapsed Time" has climbed to 16:57:05, and the message "Writing catalog to tape ... " remains visible.

But, a read of the manual found me a log at /Library/Application Support/BRU PE/log/bruexeclog, and in there I found this:

So my first thought was -- now that it's been a while and I've rebooted and the tape drive appears to be online, maybe I can use the command listed in that log to write the catalog to the tape. I put some quotes around things to make everything sane, hopefully in the proper manner:

MacPro:~ zachfine2$ sudo /usr/local/bin/bru -cf ntape0 -L '#CATALOG - 5b249cf78ad8' -QB "/Library/Application Support/BRU PE/tmp/BRU-5b249cf78ad8"


This appeared to do something:

20180616 22:21:48|20904|root|[L163] START (r 18.1.1.28), CMD = '/usr/local/bin/bru -cf ntape0 -L #CATALOG - 5b249cf78ad8 -QB /Library/Application Support/BRU PE/tmp/BRU-5b249cf78ad8'
20180616 22:21:48|20904|root|[L167] device = ntape0, buffer = 128K bytes, media size = <unknown>, archive id = 5b25efec51a8, (Op)
20180616 22:21:48|20904|root|[L182] wrote 6720 blocks (13440 KBytes) on volume [1], 0:00:00, 99999 KB/sec
20180616 22:21:50|20904|root|[L165] FINISH - 0 warnings, 0 errors, exit code = 0


So I guess my question is -- did I do the right thing to complete the backup? Or did I just do something daft like overwrite part of my backup with the catalog file? Are there more steps?

My initial thought is to just start over with a new backup, overwriting the tape, because this is all just a bit messy. And I'll do it from the BRU PE GUI once again because I'm not feeling comfortable yet in my knowledge of the BRU command line.
