How to get snapshot CRs populated on a fresh k8s cluster

[bfeher-kx]

Hi!

I wonder if there is a simple way to have the snapshots CR populated based on the restic repo.

I seen that if I start a backup its gets fetched and populated, even found which module is doing it.

https://github.com/k8up-io/k8up/blob/master/restic/kubernetes/snapshots.go

Is there a way to call this directly?

Hi @bfeher-kx

Currently the snapshots only get syncrhonized after the backup with the code snipped you linked. It can't be called directly.

I'm also wondering why you'd need that. Could you please elaborate your use-case? Then I may be able to understand your need better.

Hi @Kidswiss

Any idea?

Are those deployments on the same cluster, but in another namespace? In that case your operator could copy the snapshot CRs and the necessary credentials to the new namespace? With the snapshot CRs and the credentials you have everything needed to restore the snapshots.

Hi @Kidswiss

The target would be a new Kubernetes cluster. We were thinking about to export the CRs and apply it on the target, but some metadata would be different then.

The metadata doesn't really matter to k8up for restores. The important parts are in the spec field. Currently we also just copy the snapshots around if we need a restore in a new namespace/cluster.
