Backup and Restore to Local storage

A few questions surrounding backups with ScyllaDB.

  1. is there any way to configure scylla manager to back up to local storage? (Or a network share). All of the documentation seem to point to an S3 bucket or azure/gcp based options.

  2. If you have a 3 node cluster with RF3 do you still need to backup and restore all nodes via snapshot? or Can you use a snapshot from one node since it has all data on it (due to rf3).
