Configuring the Backup Service

Some Backup Service options can be configured in the OpsCenter UI.

Procedure

  1. Click the name of the cluster you want to manage from the left navigation pane and click Services.
  2. Click View Details for the Backup Service.
  3. Click the Settings tab.
  4. To enable commitlog backups, see the instructions on enabling commitlog backups.
  5. To set a disk space threshold below which backup operations will not start, click Configure under Disk Space Threshold.
    1. Check the box and set the percentage of free space that must exist in order for a backup operation to start, then click Save.
  6. Click Configure under Encryption Key Storage to set enable or disable whether OpsCenter will store the encryption keys for each node along with the SSTables. This is enabled by default, and highly recommended.

    If Encryption Key Storage is enabled and your cluster has encrypted keyspaces, the encryption key for each node will be stored in the backup location along with the data. If you disable this option you must ensure that each node's encryption key is available before attempting to restore encrypted tables.

    1. Set the slider to On to enable, or Off to disable, storing encryption keys alongside the backup data, then click Save.
