The server plan that you select for the Couchbase cluster manages scheduled backups. You can also perform on-demand backups of bucket groups at any time.
Staging Requirements for Couchbase Backups
For shared staging path, the recommended average size of staging space needed is equal to the size of the biggest bucket selected for backup multiplied by the number of nodes associated with the couchbase instance and 0.01% of the bucket size per job for metadata.
For the non-shared staging path, the recommended average size of staging space needed is equal to the size of the biggest bucket selected for backup and 0.01% of the bucket size per job for metadata.
