Gitlab not backing up to s3. Where can I find logs?

Question

I am currently trying to migrate our old sameersbn/gitlab:12.1.6 installation to a new Gitlab instance set up with the helm chart.

The easiest way seems to enable the s3 backup capability on the old installation, connect the new instance to the same s3 and restore it from there.

Currently I am stuck with correctly configuring the old installation. I set a bunch of environment variables on the docker container and expected this to work out of the box.

-e "AWS_BACKUPS=true" \
-e "AWS_BACKUP_MULTIPART_CHUNK_SIZE=500" \
-e "AWS_BACKUP_ACCESS_KEY_ID=minio" \
-e "AWS_BACKUP_SECRET_ACCESS_KEY=minio" \
-e "AWS_BACKUP_REGION=main" \
-e "AWS_BACKUP_BUCKET=gitlab-backup-storage" \
-e "AWS_BACKUP_ENDPOINT=https://minio.com"

But it doesn't. I couldn't see any errors in the docker logs, so I checked the /var/log/gitlab folder with no success. Some other logs, but none indicate whether the backup started/succeeded/failed and I cannot see any backups in the s3 bucket.

Now I don't know where to look and what to check.

Have you inputted your "actual" values for Key/Secret/Region/Bucket/Endpoint values? That endpoint is for sure good? — emmdee, Jan 08 '20 at 18:03
Yes, I use the same setup/s3cfg in the Gitlab instance installed via helm chart and I can restore manually uploaded backups with it. — Moritz Schmitz v. Hülst, Jan 09 '20 at 07:53

You might want to manually start the backup process by running

/home/git/gitlab/bin/rake gitlab:backup:create --trace

inside the docker container. You then get an output which states what the problem is.

I had a similar problem and could not upload to wasabi. Turns out my configuration, especially my endpoint was wrong. This is the config I am successfully using:

    - AWS_BACKUPS=true
    - AWS_BACKUP_REGION=eu-central-1
    - AWS_BACKUP_ENDPOINT=https://s3.eu-central-1.wasabisys.com
    - AWS_BACKUP_ACCESS_KEY_ID=some-id
    - AWS_BACKUP_SECRET_ACCESS_KEY=some-secret
    - AWS_BACKUP_BUCKET=gitlab-backups
