Requirements for Using Snapdiff on Network Share

If you want to use NetApp SnapDiff for faster incremental backups, verify that your environment meets the system requirements.

System Requirements

For system requirements for MediaAgents as proxy computers, read the following topics:
- For system requirements for indexing, see System and Hardware Requirements.
- For system requirements for MediaAgents, see MediaAgent: System Requirements.
For system requirements for the file system agents, read the following topics:
- For the Linux file system agent, see Linux File System Agent: System Requirements.
- For the Windows file system agent, see Windows File System Agent: System Requirements.

Requirements in the Commvault Software

You must create subclients with Commvault FR 11.23 or a more recent release.
You must enter array credentials for the array. See Editing the User Credentials or Description of a Storage Array.

File Server Requirements

To set up an account to log on to the file server, see Frequently Asked Questions for the NetApp Storage Array. These login credentials enable SnapDiff V1.

To set up SnapDiff V2 which is faster than V1, RPC must be enabled on the vServer and there must be an NFS interface between the vServer and Commvault access-node or MediaAgent running the scan. To configure RPC and an NFS interface, execute the following commands.

vserver snapdiff-rpc-server on <vserver_name>

network interface show -vserver <vserver> -data-protocol nfs

Note

Please verify the above commands with NetApp documentation.

Ports

For snapshot-based operations, open port 443 (HTTPS) for communication between the NetApp server and CommServe computer, MediaAgent, access node or remote snapshot MediaAgent in your CommCell environment.
For SnapDiff V2 and V3, open port 2049 (NFS) for communication between the NetApp server and CommServe computer, MediaAgent, access node, or remote snapshot MediaAgent in your CommCell environment to transfer the file list information over NFS.
