Azure Backup SQL VM Configure Backup fails for new Always on AG - BMSUserErrorContainerObjectNotFound

Question

Can anyone help with this?

I started to get this error last week when I try to configure backup on any newly discovered AG. This was all working just fine prior to last week. This is happening across multiple SQL Servers in our environment.

All other previously configured AGs are still working fine, and I can successfully configure backup for any SQL DBs that are outside of the new AGs. Only seems to be newly discovered AG

Error Code

BMSUserErrorContainerObjectNotFound

Error message

Item not found

Recommended action

Hi @Adam Rice,

Backup service is unable to locate the specified item, which in your case seems to be related to newly discovered Availability Groups (AGs). Here are some steps you can take to troubleshoot and resolve this issue:

1. Permissions Issue:
   • Ensure that the account used by the backup service has the necessary permissions to access and manage the Availability Groups.
   • Verify that the account has the sysadmin role on the SQL Server instances hosting the AGs. For backup the account should have Sysadmin privileges to the sql server instance
2. Re-Registering the VM:
   • Sometimes, re-registering the Availability Groups with the backup service can resolve such issues.
   • Remove the AGs from the backup configuration and then re-add them.
3. Region & Recovery Vault Considerations:
   • The VM must be in the same region as the old Recovery Services Vault (RSV). Otherwise, it won’t appear.
   • If necessary, unregister the VM from the old RSV, remove it, and add it to the new one.

Feel free to reach out if you have any further questions or need additional information—I’m happy to assist!
