Does database backup affect performance?
Backups should not cause performance problems as such operations do not take locks on user objects.
Which recovery model allows for point in time restores of data?
full recovery model
Since every transaction is being written to the transaction log, the full recovery model supports point-in-time restores, meaning a database that is fully logged can be restored to any point in time.
How do you put a database in restoring mode?
The steps look like this:
- Back up the tail of the log for each database on the Primary, making sure to leave them in NORECOVERY mode.
- Apply the tail of the log for each database on the Secondary, bringing the LSNs in line with the Primary.
- Bring the Secondary online.
What are different types of recovery models in SQL Server?
Three recovery models exist: simple, full, and bulk-logged. Typically, a database uses the full recovery model or simple recovery model. A database can be switched to another recovery model at any time.
How to restore a database from another server?

For more information about restoring from the Microsoft Azure Blob storage service, see SQL Server Backup and Restore with Microsoft Azure Blob Storage Service.
What to do when database is stuck in restoring state?
If the database is stuck in the restoring state and you don’t have additional backups to restore, you can recover the database using the following command: Once you issue this command, the database will be useable, but you won’t be able to restore any additional backups for this database without starting all over again with the full backup.
What are the arguments for restore in SQL Server?
For descriptions of the arguments, see RESTORE Arguments. SQL Server supports a variety of restore scenarios: Restores the entire database, beginning with a full database backup, which may be followed by restoring a differential database backup (and log backups).
Can You restore a database from a geo-replicated backup?
You can restore a database on any SQL Database server or an instance database on any managed instance in any Azure region from the most recent geo-replicated backups. Geo-restore uses a geo-replicated backup as its source. You can request geo-restore even if the database or datacenter is inaccessible due to an outage.
