There are two backup types: Logical-backup (or simply "Backup") and Snapshot.
A logical backup is a compressed JSON dump of database contents, including documents, index definitions, and additional data
that can be stored in full and incremental backups.
After a database restore, the dataset is re-indexed by the backed-up index definitions.
This can be time-consuming in large datasets.
A snapshot is a binary image of the database contents, full indexes, and additional data
at a given point in time.
- Restoration time is reduced because no re-indexing is needed, but more data is transferred during backups.
Incremental Snapshot backups
(the changes made since the last backup) do not incrementally update indexes or change vector data after the initial complete Snapshot image.
Snapshots are only available for Enterprise subscribers.
