Refer to the Barraucuda Networks Knowledgebase Solution “How to use the Recovery Storage group 
feature for Microsoft Exchange with the Barracuda Backup Service?” at

for detailed instructions.

When you request the restore of a Microsoft SQL user database, the Barracuda Backup Service will 
perform 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 will restore all intermediate required database revisions.

On the 

page

select the day and time from which you want to 

restore.

Select the data source from which you want to restore.

Select the database(s) to restore and click 

.

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 Barraucuda Networks Knowledgebase Solution “How do I restore a SQL database with 
the Barracuda Backup Service?” at

for instructions for restoring a SQL master 

database.

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 
Barraucuda Networks Knowledgebase Solution “How can I perform a System State Restore from my 
Barracuda Backup Service on a Windows 2008 server?” at

These instructions also describe how to restore System State on a Windows 2008 Active Directory 
domain controller.
