I’ve been unable to use Velero/restic to backup a Gluster volume. I saw in the logs it said volume type not supported. Is there a list somewhere of restic plugins and volume type support?
restic itself should be able to backup any filesystem that shows up as regular part of the local filesystem tree. The supported backup destination types are described at https://restic.readthedocs.io/en/stable/030_preparing_a_new_repo.html .
Afaict the words “volume type” are not contained anywhere in the restic source code. Could you please post the relevant log excerpt along with more information on the used version of restic?
