difference between snapshot and snapshot replication


hi,

i confused difference between snapshot , snapshot replication.
when need use snapshots in sql server 2005

hi michael,

1.database snapshots :
database snapshots new enterprise edition-only tool, introduced in sql 2005, provide read-only, "virtual" copy of database, @ given point in time.
2.snapshot replication:
snapshot replication distributes data appears @ specific moment in time , not monitor updates data. when synchronization occurs, entire snapshot generated , sent subscribers.
3.major difference:
snapshot replication can used itself, snapshot process, creates copy of objects , data specified publication, commonly used provide initial set of data , database objects transactional , merge publications.
4.the purpose have use snapshots in sql server 2005:
database snapshots allows create read-only copy of database can used other purposes, such reporting, auditing or recovering data. currently, can running backup , restoring database. however, big advantage gain using database snapshots instead speed @ snapshot occurs, ability create multiple snapshots @ different points in time quickly.
