How to get a backup of filesystem volume with Kopia CLI?

[krzwiatrzyk]

Like in the title, I have a backup of a volume that was mounted to a pod. This backup is in Minio storage. I can properly restore this volume with Velero restore feature.

However, I want to ensure that in some misterious cases I will be able to work on a volume backup. As I know that filesystem backup is performed via Kopia, I have installed Kopia CLI and pointed to S3 bucket (and path) where my volume is.

And:

1. kopia repository connect s3 <-- success
2. kopia snapshot list --all <-- empty output
3. kopia contents size <-- 0B

And I wonder, doesn't using some custom kopia code break integration with Kopia CLI directly? Is it event possible anymore to get/decrypt that thata without restoring it into pod filesystem?

Velero do use a static password on kopia backups in addition, check bsl bucket prefix is added to kopia path.

It is, I connect to bucket with that command:

      kopia repository connect s3
      --access-key "ACCESS_KEY_ID"
      --secret-access-key "SECRET_ACCESS_KEY"
      --disable-tls
      --endpoint=<minio-address>
      --bucket=backups
      --prefix /kopia/maypp/
      --password=$PASSWORD

And this command is successful, If I would provider incorrect prefix than there is an error that in that path there is no repository

Try this

Since you have connected to the kopia repo, could you run kopia repo status kopia snapshot list --all kopia content stats, and share the outputs?
