While a physical backup is a physical copy of your data directory, a snapshot is a point in time copy of your disk or a volume where the data files are stored. Restoring from snapshots is much faster and allows almost immediate access to data, while the database is unavailable during physical restore. Snapshot-based backups are especially useful for owners of large data sets with terabytes of data. Yet the snapshots don’t guarantee data consistency in sharded clusters.
