We have several backup copy jobs (configured as a storage copy option between two HPE StoreOnce's) failing due to unable to delete a restore point. We have enabled immutability on both source and target repositories.
The actual error message we receive is as follows, "Failed to call RPC function 'PluginsHost.StoreOnceCreateEmptyFile': OSCLT_ERR_OBJECT_LOCK_FAILED. Err: -1909. Failed to delete Object |JOBNAME|RESTORE POINT OF A VM on Store CATALYST STORE.
Veeam Case#07815482
Support responded with the following action items
- Reboot StoreOnce
- Reboot associated Mount server
- Upgrade StoreOnce FW
- Make sure the StoreOnce is not being accessed at the same time by multiple backup jobs.
We responded by rebooting both StoreOnce and associated mount server and scheduling a different backup time. But we are still having the same issue.
Not sure of next steps.
