Is it possible to backup/restore using restic without remote bucket

[Ilyes512]

Is it possible to backup a kind cluster using restic and store the "snapshot"/result locally on your own machine. I just want to create snapshot of my dev cluster so I can restore it after, for instance, a reboot of my laptop.

@Ilyes512 it is possible. There is a limitation, though, in that velero's restic integration can't back up hostPath volumes/PVs - so if you're using kind's hostPath provisioner for PVs, you won't be able to back those up. You could use emptyDir volumes as an alternative, if possible.

Here's one way to do it using minIO (I just tried this out and it worked, barring the hostPath limitation):

• run a minIO instance locally on your laptop - this will be your S3-compatible object storage provider (see https://docs.min.io/docs/minio-quickstart-guide.html if you need more detail)
• roughly follow the steps here to install velero using minio, with a few modifications:
  • in step 1, use the credentials that minio gave you when you started running it on your laptop
  • you don't need to run the first command in step 2 (00-minio-deployment.yaml), since you already have minio running on your laptop
  • your velero install command should look like the following:

velero install \
    --provider aws \
    --bucket <YOUR-MINIO-BUCKET> \
    --secret-file ./credentials-velero \
    --backup-location-config region=minio,s3ForcePathStyle="true",s3Url=http://<YOUR-LAPTOP-HOSTNAME>.local:9000 \
    --use-volume-snapshots=false \
    --use-restic

Let us know if this works for you!

Yeah... should have maybe waited or updated my question... but I am now playing with minio and reading the docs. Although I think it's a bit much and It should be easier (with less deps) to do.

But I will try it anyways so your instructions will come in handy :)

@Ilyes512 we have #1229 to support non-object-store backends and #1178 to support additional restic backends. Perhaps those would cover some of what you're looking to do - feel free to add comments on either/both! I'm going to close this out for now, but feel free to reach out again as needed.
