Snapshot Replication provides schedulable, near-instantaneous data protection, ensuring business data in shared folders, and virtual machines in iSCSI LUNs, remain safe and available in the event of disaster.
Similarly, it is asked, what is a NAS snapshot?
Snapshot is a technology that provides efficient time-based archives of data so that each user can quickly restore a file accidentally deleted or changed to its previous state on his/her own. Snapshot supports only directories and files in Research Computing's NAS Filesystems: home and dept spaces.
Subsequently, question is, what is an iSCSI snapshot? A snapshot of an iSCSI LUN is a point-in-time, read-only copy of an iSCSI LUN. It saves a significant amount of time and storage capacity when compared with traditional LUN backups. Each individual LUN supports up to 256 snapshot versions.
Additionally, how do I create a snapshot in Synology?
Click on snapshots. Click on the folder you want to create a scheduled snapshot. Click on Settings.
On the Schedule tab, select your schedule settings:
- How often ( I pick daily)
- Frequency: every day.
- and when the snapshot should be done ( I always pick at night, so all the work has be done and it is ready for a backup)

Snapshot replication refers to a replication method between databases. During this process, data is infrequently updated at specified times by copying data changes from the original database (publisher) to a receiving database (subscriber).

Snapshot replication works slightly differently than transactional replication. A snapshot is bit slower than transactional because on each attempt it moves multiple records, perhaps millions of records, from one end (the publisher) to the other end(the subscriber).What are the different types of replication?

- Transactional replication.
- Snapshot replication.
- Merge replication.
- Key-based incremental replication.
How does Snapshot replication work?
