ACC Backups to S3 Storage on Rancher RKE2 deployment stops at 20%
Applies to
- Astra Control Center 22.11.0
- Rancher RKE2 with CIS-1.6 Config in Rancher
- Kubernetes up to 1.24.x
Issue
After having discovered the applications using trident provided PVCs in a Rancher Kubernetes cluster, when attempting to run a Backup in ACC, it passes the Snapshot phase for the full 100%, but stops at 20% of the S3 backup:

After fully failing the backup, in the
astra/netapp-acc/nautilus-<UID>/nautilus-<UID>.log
from the Astra support bundle logs(normally visible \n\t between the lines have been replaced with newline here, to split the trace):
Operation thread exiting: timed out waiting for job response
