Subject: [bug#71639] [PATCH WIP 0/5] Improve on restic-backup-service
Date: Tue, 18 Jun 2024 18:06:39 -0400

Hi all!

This is the previously promised [1] patch series relating to
restic-backup-service. The highlights:

1. init? was added that bootstraps a new backup.

2. RESTIC_PASSWORD_COMMAND support.

3. Add extra-packages field for jobs.

4. Move restic from restic-backup-job to restic-backup-configuration.

5. Add a basic system-level test suite.

Regarding 4, the previous way felt a bit orthogonal to how services of a
similar nature work. (For example, you don't specify an mcron package for
every job.) I can't think of a use case for mixing-and-matching restic
packages with different jobs. If there is a reason, I think a good compromise
would be a "restic-override" job field.

I'm marking this as WIP because there are a couple more things I want to
investigate, but it feels complete enough to submit for feedback. My main
point of interest is what can be done to improve support for Restic's other
backends, see [2]. I imagine 0.9.6 only supports a subset of those, but still.

In my dream world we could combine this patch with an upgrade to the restic
package itself (which, among other things, supports compression). I asked the
developers about (re)including a vendor directory in their tarball but haven't
heard back [3]. Perhaps this service can spark some action on an old Guix
tracking issue [4].
