Backup jobs stop working with NetApp SteelStore Cloud Integrated storage after upgrading to Veeam version 9

Aafter upgrading Veeam Backup & Replication to version 9, backup jobs to a NetApp repository based on a SteelStore host platform fail. The following error message can be seen in the job logs:
“Error    File not found. File name: \\PathToShare\BackupFolder\JobName.vbm”

The NetApp log containts the following error:
“rename not allowed between pinned share and unpinned share, source = /fs/PathToShare/BackupFolder/JobName.vbm_1_tmp destination = /fs/PathToShare/BackupFolder/JobName.vbm”

The .vbm file contains backup chain metadata, so this file has to be updated during every job run. To prevent possible metadata corruption, the update is divided in two steps: saving content to .vbm_tmp and renaming vbm_tmp to .vbm. Such renaming is not allowed on the SteelStore repository due to a NetApp limitation. This limitation only applies to SteelStore versions older than 3.3. Veeam Backup & Replication version 9 is officially supported by NetApp starting with SteelStore 3.3.

Upgrade SteelStore to version 3.3. If this is not possible, you can select a different repository for your backup jobs or continue to use Veeam Backup & Replication version 8.
