No output when backing up to Backblaze B2

I’ve been using restic to backup files to my Backblaze B2 bucket via an automated weekly cron job for about a couple of years now. Upon checking a short while ago though, it looks like no backups have been created since July 2019.

When I manually run “restic snapshots”, I get no textual output on the terminal, even after leaving it for a few days. I just tried to create a new B2 bucket and initialize a new restic repository in it, but I run into the same issue. Creating a local repository seems to work though. I tried changing my B2 master key and updating the B2_ACCOUNT_KEY environment variable, but still the same issue. I was using restic 0.8.0 on Linux Mint eariler, so I tried testing with restic 0.9.6 and still the same issue.

Any ideas what might be going wrong are much appreciated.

Please take a look directly at the original B2 bucket. Every restic repository has a snaphots directory which contains 1 file per snapshot in your repository. Anything in there?

The newest file in the snapshots directory of the original bucket was created in July 2019. The newly created bucket is empty despite trying to initialize a new repository in it.

If you run a backup manually, does the output contain any errors?

Again, the command hangs with no textual response. Screenshot attached.

Can you run with -vv?

It gets stuck at this point:

% ~/bin/restic backup --cleanup-cache --files-from=include_uc.txt --exclude-file=exclude_uc.tx -vv
open repository

Hmm. Is the process doing any network I/O when it gets stuck? Can you kill it with SIGABRT and paste the resulting stack dump?

Sorry, am not that experienced with this type of troubleshooting. Could you please advise how I might go about getting this information.

Assuming you have no other restic processes running, try pkill -6 restic. If that doesn’t work, use ps aux | grep restic to find the PID of the restic process, then run kill -6 THAT_PID. You can do this in a separate terminal than the one running restic.

Thanks a lot @rawtaz. Here’s the output after killing the process using pkill -6 restic:

 % ~/bin/restic backup --cleanup-cache --files-from=include_uc.txt --exclude-file=exclude_uc.tx -vv
open repository
