velero backups failing for "backup resource list not found"

Question

After the upgrade of velero from 1.3.2 to 1.7.7 backups started failing. When describing the failing backup:

velero backup describe mypod-20220204170020 --details


Name:         mypod-20220204170020
Namespace:    velero
Labels:       velero.io/schedule-name=mypod
              velero.io/storage-location=default
Annotations:  velero.io/source-cluster-k8s-gitversion=v1.21.2
              velero.io/source-cluster-k8s-major-version=1
              velero.io/source-cluster-k8s-minor-version=21

Phase:  Failed (run `velero backup logs mypod-20220204170020` for more information)

Errors:    0
Warnings:  0

TTL:  168h0m0s

Backup Format Version:  1.1.0

Started:    2022-02-04 18:00:20 +0100 CET
Completed:  2022-02-04 18:00:41 +0100 CET

Expiration:  2022-02-11 18:00:20 +0100 CET

Total items to be backed up:  64
Items backed up:              64

Resource List:  <backup resource list not found>

Velero-Native Snapshots:  <error getting snapshot info: file not found>

At first sight it seems like the backups were made correctly:
Errors: 0
Warnings: 0
Items backup: 64 of 64

However, right at the bottom (and only when adding the --details flag with the describe command), you see these two mentions:

Resource List:  <backup resource list not found>
Velero-Native Snapshots:  <error getting snapshot info: file not found>

Is there some clever way to troubleshoot this further? Or do someone have thoughts on what might be the issue here?

• Running on AKS (1.21.2)
• Using velero-plugin-for-microsoft-azure:v1.3.1 for snapshots to azure

Much appreciated!

I need to know where your data reside means it is using azure disk, or in file share.. Velero does not support azure file share data
