k10 cannot perform any OKD resource backup #4344569

If the number you added to the subject of this post is a case number you will need to work with support as we don't provide tech support on the community.  If you have more details on the errors or logs that you can post some may be able to help but not at the tech support level.

The last full backup was successful on 2023/10/24 Tue 5:14am – 5:23am, and the full backup has failed since then.

Occasional delay at night due to disk performance limitations has always existed, but in spite of the ETCD delay, it was normal for K10 full backup before October 24th. ETCD monitoring is back to normal, but k10 is still unable to perform backup tasks.

We've simplified the police so that only part of the resources of a namespace is backed up.

The k10 task remains in the "Snapshotting Application Components" state and cannot be completed, and no error is returned.
