Snapshot Replication

  1. 1.  Introduction Agents required When to use Pros n Cons Implementation with an example• Q&A
  2. 2.  Snapshot replication distributes data exactly as it appears at a specific moment in time and does not monitor for updates to the data. When synchronization occurs, the entire snapshot is generated and sent to Subscribers.
  3. 3.  Snapshot agent creates the snapshot of the publisher. Distribution agent applies the snapshot to the subscribers.
  4. 4.  Data changes infrequently. Latency in synchronization of data between publisher and subscriber is acceptable. Thesize of entire data set being replicated is not very large.
  5. 5.  Pros- Snapshot replication has lower overhead on publisher than transactional/merge replication because incremental changes are not tracked. Cons - If the dataset being replicated is very large, snapshot replication requires substantial resources to generate and apply the snapshot.
