By default, the MediaAgents that are associated with the storage that is specified in the storage plan are used as access nodes to back up CIFS shares and NFS exports. These MediaAgents have permissions to mount and access shares from the NAS file server. However, if you do not want to use MediaAgents that have those permissions for security or other reasons, then use different access nodes.
Considerations
-
Access nodes are used with the network share file system agents under the file server.
-
For CIFS/SMB shares, install the Windows File System package on the access node you want to use. For information about system requirements for Windows file system, see System Requirements for Windows.
-
For NFS exports, install the Linux File System package on the access node you want to use. For information about system requirements for Linux file system, see System Requirements for Linux File Systems.
-
-
Ensure that an access node has connectivity to the NAS file server.
-
Commvault recommends having a minimum of two access nodes for both redundancy and performance reasons.
-
Load balancing across nodes is better when using CIFS shares. For example, if backing up 400 TB data, Commvault recommends using four medium-sized access nodes with fewer streams each than one Extra large-sized access node with maximum streams.
-
Perform IntelliSnap backup to reduce file locking issues and to back up a frozen copy of the data.
-
For IntelliSnap backup of CIFS Shares and NFS Exports, ensure that the MediaAgent package is installed on an access node.
-
Leverage block-based replication for copies of data on the client and then backup the snapshots needed for longer term retention.
-
Recommended indexing limit of up to two billion files on each subclient.
-
For UNIX systems, if there is a firewall between the MediaAgent and the file server (client), then verify that your environment meets the following requirements:
-
The Commvault Communications Service (CVD) port and the tunnel port must be open bidirectionally. The tunnel port is the CVD port plus 3. For example, if the CVD port is 8400, then the tunnel port is 8403. If the CVD port is not open, then client creation or protocol addition fail.
-
If there are traffic-pattern rules in third-party firewalls, you must turn these rules off. If you don't turn those rules off, the connectivity check between the file server and the storage MediaAgent fails.
-
-
Streaming/regular backups and backup copy operations use the MediaAgents associated with primary copy of the storage policy. Snapshot backups use the MediaAgent associated with the snapshot copy of the storage policy.
