Configuring Distributed Storages As a Disk Library

Distributed Storages can be configured as a storage library.

Before You Begin

  • Mount the virtual disks on the MediaAgent/proxy so that it can be configured as a storage target.

  • Create Deduplication Database (DDB) partition and an Index Cache folder on the NVMe disk,on the MediaAgents/proxies as follows. This is recommended for better performance.

    # mkdir /ws
# mkfs.xfs /dev/<nvme_vol_name>
# mount /dev/<nvme_vol_name> /ws
# mkdir –p /ws/ddb/<DDB_partition_name>
# mkdir -p /ws/IndexCache
# cd /opt/Commvault/Commvault/MediaAgent
# ln -s /ws/IndexCache/IndexCache IndexCache

Procedure

  1. From the Command Center go to Storage > Disk in the navigation pane.

    The Disk page appears.

  2. In the upper-right corner of the page, click Add to add a disk storage.

    The Add disk dialog box appears.

  3. In the Name box, type a name for the storage library.

  4. From the MediaAgent list, select the MediaAgent in which the NFS share from which the Distributed Storage is mounted.

  5. Click Local Path and in the Backup location box, enter the mount path location. For example: /ws/hedvig/CommvaultBackup.

    Note

    Where CommvaultBackup is the name of the vdisk.

  6. Slide the Use deduplication toggle key to the right, to enable deduplication on the storage.

  7. Browse and select the DDB path created in the NVMe disk, in the Deduplication DB location box.

    Add additional partitions DDB associated with the other MediaAgents/proxies in the setup. For more information about configuring additional DDB partitions, see Configuring Additional Partitions for a Deduplication Database.

  8. Click Save.

What to Do Next

  • Configure the Index Cache to point to the Index Cache folder on the NVMe disk. For more information on adding the Index Cache folder in the MediaAgent, see Moving the Index Cache Directory.

  • Perform a test backup and a test restore to ensure that the Distributed Storages are functioning properly.

  • Make sure to change your root and login passwords to secure your environment.

  • Depending on your environment and requirements, you can perform one or more of the following tasks to utilize the Distributed Storages as a backup target.

    • Create Plans using the Distributed Storages as a backup target.

    • Associate the plan with subclients to be backed up, and create necessary backup schedules.

    • Create copies of the backup data using Storage Copies.

  • For information on managing the Distributed Storages, see Hedvig User Guide.
