What does the recovery model do in SQL Server?
SQL Server backup and restore operations occur within the context of the recovery model of the database. Recovery models are designed to control transaction log maintenance.
What does a backup set do in SQL Server?
Contains a row for each backup set. A backup set contains the backup from a single, successful backup operation. RESTORE, RESTORE FILELISTONLY, RESTORE HEADERONLY, and RESTORE VERIFYONLY statements operate on a single backup set within the media set on the specified backup device or devices.
Can a database be restored in simple recovery mode?
The following features cannot be used in simple recovery mode: Changes since the most recent backup are unprotected. In the event of a disaster, those changes must be redone. Can recover only to the end of a backup. For more information, see Complete Database Restores (Simple Recovery Model).
How to retrieve SQL Server database backup history?
This data is then combined via the UNION statement to the second portion of the query. That second statement returns information on all databases that have no backup history. I’ve taken the liberty of singling tempdb out from the result set since you do not back up that system database.
Is it possible to replication MS SQL Server 2008?
Replication will not work if you install MS SQL Server 2008 on the second machine. For example, if you want to configure MS SQL transactional replication, you can use the second database server (where the Subscriber is configured) of a version within two versions of the source database server on which the Publisher is configured.
How does merge replication work in SQL Server?
When the network connection is established between both database servers, merge replication agents detect changes made on both databases and modify databases to synchronize and update their state. Merge replication is similar to transactional replication, but data is replicated from the Publisher to the Subscriber and inversely.
How does transactional replication work in SQL Server?
In the beginning of the transactional replication process, a snapshot is applied to the Subscriber and then data is continuously transferred from a master database to a database replica after being changed. Transactional replication is widely used as one-way replication.
