If bulk changes exist in the database, all files must be either online or defunct. This means that it is no longer part of the database. We recommend switching to the full recovery model before starting an online restore. The Database Recovery Advisor facilitates constructing restore plans that implement optimal correct restore sequences.
Many known database restore issues and enhancements requested by customers have been addressed. Major enhancements introduced by the Database Recovery Advisor include the following:.
Restore-plan algorithm: The algorithm used to construct restore plans has improved significantly, particularly for complex restore scenarios. Many edge cases, including forking scenarios in point-in-time restores, are handled more efficiently than in previous versions of SQL Server.
Point-in-time restores: The Database Recovery Advisor greatly simplifies restoring a database to a given point in time. A visual backup timeline significantly enhances support for point-in-time restores. This visual timeline allows you to identify a feasible point in time as the target recovery point for restoring a database. The timeline facilitates traversing a forked recovery path a path that spans recovery forks.
A given point-in-time restore plan automatically includes the backups that are relevant to the restoring to your target point in time date and time. Recovery Advisor: An Introduction. Accelerated database recovery is available in SQL Server Accelerated database recovery greatly improves database availability, especially in the presence of long-running transactions, by redesigning the SQL Server Database Engine recovery process. A database for which accelerated database recovery was enabled completes the recovery process significantly faster after a failover or other non-clean shut down.
When enabled, Accelerated database recovery also completes rollback of canceled long-running transactions significantly faster. You can enable accelerated database recovery per-database on SQL Server Skip to main content. This browser is no longer supported. Download Microsoft Edge More info. Contents Exit focus mode. Restoring a damaged master database is performed using a special procedure.
Restoring a database clears the plan cache for the database being restored. Clearing the plan cache causes a recompilation of all subsequent execution plans and can cause a sudden, temporary decrease in query performance.
To restore an availability database, first restore the database to the instance of SQL Server, and then add the database to the availability group. To restore a database that is encrypted, you must have access to the certificate or asymmetric key that was used to encrypt the database. Without the certificate or asymmetric key, the database cannot be restored.
As a result, the certificate that is used to encrypt the database encryption key must be retained as long as the backup is needed.
Backup and restore work correctly with the vardecimal storage format. Full-text data is restored together with other database data during a complete restore. The RESTORE statement also can be used to perform restores to alternate locations, differential restores, file and filegroup restores, and differential file and filegroup restores of full-text data. Full-text catalogs imported from SQL Server 9. For these, the SQL Server 9.
Certain operations, including configuring server instance level settings, or manually adding a database to an availability group, require a connection to the SQL Server Instance.
By default, a big data cluster does not include an endpoint that enables a connection to the instance. You must expose this endpoint manually. For instructions, see Connect to databases on the primary replica.
SQL Server includes backup and restore history tables that track the backup and restore activity for each server instance. When a restore is performed, the backup history tables are also modified. For information on these tables, see Backup History and Header Information.
Restore normally prevents accidentally overwriting a database with a different database. This is an important safeguard. The overridden checks are as follows:. With the REPLACE option, restore allows you to overwrite an existing database with whatever database is in the backup set, even if the specified database name differs from the database name recorded in the backup set.
This can result in accidentally overwriting a database by a different database. Restoring over a database using the full or bulk-logged recovery model where a tail-log backup has not been taken and the STOPAT option is not used. For example, a mistake could allow overwriting files of the wrong type, such as.
Arbitrary data loss is possible if existing files are overwritten, although the restored database is complete. Undoing the effects of a restore is not possible; however, you can negate the effects of the data copy and rollforward by starting over on a per-file basis. To start over, restore the desired file and perform the rollforward again. For example, if you accidentally restored too many log backups and overshot your intended stopping point, you would have to restart the sequence.
A restore sequence can be aborted and restarted by restoring the entire contents of the affected files. Only the snapshot to which you are reverting can currently exist. The revert operation then rebuilds the log therefore, you cannot later rollforward a reverted database to the point of user error. Data loss is confined to updates to the database since the snapshot's creation. The metadata of a reverted database is the same as the metadata at the time of snapshot creation.
However, reverting to a snapshot drops all the full-text catalogs. Reverting from a database snapshot is not intended for media recovery. Unlike a regular backup set, the database snapshot is an incomplete copy of the database files. If either the database or the database snapshot is corrupted, reverting from a snapshot is likely to be impossible.
Furthermore, even when possible, reverting in the event of corruption is unlikely to correct the problem. I had the same problem. In my case the problem was related to trying to restore in an old sql server folder that existed on the server.
This is due to old sql server backup i. I had the same issue while restroring database and tried every solution but could nt get resolved. Then i tried to re install SQL and the problem solved. Actully last time i forgot to check on customize option while instlling SQL.. It comes two times while installing and i checkd it for ones only.. In my case - I had to double check the Backup path of the database from where I was restoring.
I had previously restored it from a different path when I did it the first time. I fixed the Backup path to use the backup path I used the first time and it worked! This can occur if the permissions for the files were reset to match the permissions of the folder of course, while the service was stopped.
The easiest solution in this case is to detach each database and attach it again because when attaching the owner is changed to be the service account. In the Restore DB wizard window, go to Files tab, Uncheck "Relocate All files to folder" check box then change the restore destination from C: to some other drive. Then proceed with the regular restore process. It will get restored successfully.
I had the same problem but I used sql server r2, you must check in options and verify the paths where sql going to save the files. I solved my problem with this, I hope it helps you. Then try moving it to a sub folder under the C:, but verify that the user has full rights on the folder your use.

For more information, see the "Permissions" section for the relevant statement. Specifies the physical block size, in bytes. The supported sizes are , , , , , , , and 64 KB bytes.
The default is for tape devices and otherwise. Explicitly stating a block size overrides the automatic selection of block size. You can specify any positive integer; however, large numbers of buffers might cause "out of memory" errors because of inadequate virtual address space in the Sqlservr.
Specifies the largest unit of transfer in bytes to be used between the backup media and SQL Server. The possible values are multiples of bytes 64 KB ranging up to bytes 4 MB.
These options allow you to determine whether backup checksums are enabled for the restore operation and whether the operation stops on encountering an error.
The default behavior is to verify checksums if they are present and proceed without verification if they are not present. CHECKSUM Specifies that backup checksums must be verified and, if the backup lacks backup checksums, causes the restore operation to fail with a message indicating that checksums are not present.
If a backup contains damaged pages, it is best to repeat the restore operation using an alternative backup that does not contain the errors-for example, a backup taken before the pages were damaged. A windows-compatible directory name. Uniqueness comparison is done in a case-insensitive fashion, regardless of SQL Server collation settings. Displays a message each time another percentage completes, and is used to gauge progress. If percentage is omitted, SQL Server displays a message after each 10 percent is completed approximately.
The STATS option reports the percentage complete as of the threshold for reporting the next interval. These options are used only for TAPE devices. If a nontape device is being used, these options are ignored. If a non-tape device is being used, these options are ignored. Specifies that SQL Server will keep the tape open after the backup operation. You can use this option to improve performance when performing multiple backup operations to a tape.
Keeping the tape open prevents other processes from accessing the tape. It prevents replication settings from being removed when a database backup or log backup is restored on a warm standby server and the database is recovered.
To ensure replication functions properly after restore:. The msdb and master databases at the warm standby server must be in sync with the msdb and master databases at the primary server. This option is relevant only if the database was enabled for change data capture when the backup was created. To extract changes from the log after restoring the database, recreate the capture process job and the cleanup job for the restored database.
For information, see sys. Turns Service Broker message delivery on or off or sets a new Service Broker identifier. This option is relevant only if Service Broker was enabled activated for the database when the backup was created. By default Service Broker message delivery is disabled during a restore.
The database retains the existing Service Broker identifier. This enables your applications to perform regular clean up for existing conversations. Service Broker message delivery is disabled until this operation is completed, and then it is enabled. Because the database is considered to be a new Service Broker, existing conversations in the database are immediately removed without producing end dialog messages.
