Issue 2: Storage Snapshot Removal Fails if SMB Share Is Processed in Less Than 10 Minutes
When interacting with an SMB-only Nutanix share, if a Veeam Backup & Replication task completes so quickly that it would cause a storage snapshot removal request to be sent less than 10 minutes after that storage snapshot was created, the storage snapshot removal may fail.
Nutanix versions below 4.2 — create the following registry value on the Veeam Backup Server and configure it to a value sufficient to force Veeam Backup & Replication to retry enough times that it finally succeeds.
Key Location: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication\
Value Name: NutanixDeleteSnapshotRetryCount
Value Type: DWORD (32-Bit) Value
Default Value Data: 3
Nutanix 4.2 and higher — Veeam Backup & Replication will skip the deletion of the snapshots "stuck" in the Marked For Delete state. The workaround is to delete stuck snapshots manually within Nutanix Files.
