Other options are:
  • -t means the following file contains the snapshot.
  • snapshot is the name of the snapshot.
  • keyspace is one or more keyspace names, separated by a space.

Description 

Deletes snapshots in one or more keyspaces. To remove all snapshots, omit the snapshot name.

CAUTION:
Removing all snapshots or all specific keyspace snapshots also removes OpsCenter backups.
Note: If clearsnapshot fails, Cassandra retries periodically, and also when the node is shutdown or restarted.
