Restoring a Microsoft SQL Database
Restoring an SQL User Database
When you request the restore of a Microsoft SQL user database, the Barracuda Backup Service
performs all of the restores required to get to the desired date, as follows:
• Restore a full backup of the SQL Server database.
• Restore the incremental backups in the order in which they were created.
In other words, if you want to restore the database to a certain date, simply select the date and that
database, and the Barracuda Backup Service restores all intermediate required database revisions.
To restore a Microsoft SQL User Database:
1.
On the
RESTORE> Restore Browser
page
,
select the day and time from which you want to
restore.
2.
Select the data source from which you want to restore.
3.
Select the database(s) to restore, and click
Restore
.
Restoring an SQL Master Database
If the master database becomes unusable, it must be restored from a previous SQL Dump or backup.
All changes made to the master database after the last backup or dump are lost when the dump is
reloaded, and therefore must be reapplied.
Refer to the Barracuda Networks Knowledgebase Solution “How do I restore a SQL database with
the Barracuda Backup Service?” at
http://www.barracuda.com/kb?id=50160000000IEEI for instructions for restoring a SQL master
database.
Restoring Windows System State
Restoring Windows System State should only be performed in a disaster recovery situation.
Typically, this is if a server goes down and is not recoverable or if the configuration is severely
corrupted.
For instructions for restoring System State for a Microsoft Windows 2008 server, refer to the
Barracuda Networks Knowledgebase Solution “How can I perform a System State Restore from my
Barracuda Backup Service on a Windows 2008 server?” at
http://www.barracuda.com/kb?id=50160000000IV6G
These instructions also describe how to restore System State on a Windows 2008 Active Directory
domain controller.
For instructions for restoring System State for a Microsoft Windows 2003 server, refer to the
Barracuda Networks Knowledgebase Solution “How can I perform a System State Restore from my
Barracuda Backup Service on a Windows 2003 server?” at
http://www.barracuda.com/kb?id=50160000000IV6B
These instructions also describe how to restore System State on a Windows 2003 Active Directory
domain controller.
