Enabling and taking snapshots in Cloudera Manager

Before you take snapshots (in Cloudera Manager) for HDFS directories, you must enable snapshots for the directories in Cloudera Manager.

To enable snapshots for HDFS directories, navigate to the directory on the Cloudera Manager > Clusters > HDFS service > File Browser tab, and click Enable Snapshots.

note
If you enable snapshots for a directory, you cannot enable snapshots for its parent directory. Snapshots can be taken only on directories that have snapshots enabled.

tip
To disable snapshots for a directory that has snapshots enabled, click Disable Snapshots. Ensure that the snapshots of the directory are deleted before you disable snapshots for the directory.
To take a snapshot of a directory or table, perform the following steps:
1. Navigate to the directory or folder.
2. Click Take Snapshot in the drop-down menu next to the full file path.
3. Specify a unique name for the snapshot.
  The snapshot name with the timestamp of its creation appears in the snapshot list.
Click Actions > Delete to delete a snapshot.

note
After you delete a snapshot, you can restore it, if required.
