Question about PVC snapshots and architecture
By the way, I got that error very often - kubernetes-csi/external-snapshotter#300 - the fix is in progress. I'm afraid about the snapshot mechanism performance. It's also a question about the GCP snapshot mechanism, so I'm gathering opinions.

My completely automated Homelab featuring Kubernetes
VolSync is a much better option than Velero IMO, Velero was created before GitOps was a thing and it really tries to do too much when all I need is a reliable way to backup and restore PVCs. If your CSI supports volume snapshots, VolSync can use the snapshot-controller to create Volume Snapshots and then mount those as a PVC to a temporary pod to then backup that up to S3. This is really great for backing up PVCs because it's not backing them up from a running workload.

Backup solution for volumes
Is it required to store it to s3? If I were U i would use native approach https://kubernetes.io/docs/concepts/storage/volume-snapshots/ with https://github.com/kubernetes-csi/external-snapshotter

What alternatives are there to Longhorn?
Maybe checkout volsync, I've been using it for 6 months and only very little complaints.
- What do you use to backup state of k8s and data from PV
-
Backups for K8s and Beyond - My attempt at a backup solution for my homelab and other devices
I found volsync to be a bit more up my alley for backups since k8up doesn't support RWO or volume snapshots. IMO VolSync a much better solution with integrations for restic, duplicati, rclone and rsync.
