Does Velero support local volumes?

Hello,

I have read that Velero does not support hostPath. But what about local volumes?

I'm assuming you're asking in relation to restic support as that is where we explicitly mention the lack of hostPath support.

It seems like local volumes are not supported. As part of our restic restore process, we will dynamically reprovision the volume and skip the restoration of the PVs:

velero/pkg/restore/restore.go

Lines 1091 to 1093 in 962a957

	case hasResticBackup(obj, ctx):
	ctx.log.Infof("Dynamically re-provisioning persistent volume because it has a restic backup to be restored.")
	ctx.pvsToProvision.Insert(name)

This means that the PV will not be restored. As local volumes don't support dynamic provisioning, it looks like you would end up with a PVC with no associated PV to bind to. I tried this out locally, and if I recreated the PV after the restore, then the restic restore would proceed and succeed.
