• Q&A
3. 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.
4. Snapshot agent creates the snapshot of the publisher.
Distribution agent applies the snapshot to the subscribers.
5. 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.
6. 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.
