Review the following best practices before using the storage virtual machine for Amazon FSx for NetApp ONTAP.
NetApp Schedules for Snapshots
Disable the native NetApp schedule for snapshots on volumes that Commvault manages. This ensures that the snapshot retention and the storage use are in line with the policies defined within Commvault. If multiple calls to create snapshots occur at the same time, then using the default setting for internal snapshot scheduling might cause contention problems. To change the default settings, you can clear the Scheduled check box for the volume from Filer View or System Manager.
Space Utilization
Ensure that sufficient disk space is available for snapshot operations and frequently monitor the disk space used by snapshots.
The space requirement for snapshots created during IntelliSnap backup can vary based on your environment. The space utilization is dependent on the number of snapshots created and the retention period defined for the snapshots.
When planning for snapshots, group LUNs according to their rate of change. For example, group LUNs with a high rate of change in the same volume and group LUNs with a low rate of change in a separate volume. When calculating the size of volumes, use the rate of change to determine the amount of space necessary for snapshots.
