Deleting snapshot files
When taking a snapshot, previous snapshot files are not automatically deleted. You should remove old snapshots that are no longer needed.
nodetool clearsnapshot command removes all existing snapshot files from the snapshot directory of each keyspace.
You should make it part of your back-up process to clear old snapshots before taking a new one.
To delete all snapshots for a node, run the
nodetool clearsnapshotcommand. For example:
nodetool -h localhost -p 7199 clearsnapshot
Tarball and Installer No-Services path:
To delete snapshots on all nodes at once, run the
nodetool clearsnapshotcommand using a parallel ssh utility.
To delete a single snapshot, run the
clearsnapshotcommand with the snapshot name:
nodetool clearsnapshot -t <snapshot_name>
The file name and path vary according to the type of snapshot. See nodetools snapshot for details about snapshot names and paths.
