Then, if needed, an operator can restore any other partition s on any other virtual network names. For cluster server users, a disaster recovery operation properly restores all the cluster node information captured during the image backup. Therefore, a recovery specifically includes restoring a node's Disk Signatures, GUIDs, and SIDs to ensure that a recovered clustered machine boots successfully with no errors. This included the ability to back up any network resource that Windows could connect to via a UNC share path.
Furthermore, UltraBac Software was also the first company to conclusively prove that a third party backup program could successfully back up and restore an active, online Windows Cluster Server configured with multiple nodes. In this test, the backed up cluster node was actively running SQL Server. The recovery trial was set up and monitored by Microsoft personnel at their Partner Solution Center on Microsoft's main campus located in Redmond, Washington.
UltraBac was installed on a networked server, and performed a backup of one of the two active cluster nodes to a stand alone tape drive. No intermediary software or steps were required — just basically boot, restore and reboot.
Network restore performance is highly dependent on connection speed, network traffic, and machine configuration. Figure 2: Steps to recover a single cluster node. TODAY Since UltraBac's debut as the first commercial backup application to successfully back up and restore an active Microsoft Cluster Server, support has been continually added for every new server operating system since NT 4.
For file based and image backups, UltraBac can freeze all open files on a single disk, or on all disks physically connected to a machine. This eliminates any requirement to boot a machine into a "safe-mode" for backup as do some competitive products on the market.
Literally just point and click for a perfect snapshot on an active 24x7 machine at any time. Using WinPE provides customers with a "universal" boot CD that comes pre-installed with every current device driver required to boot any Wintel machine. The Windows based wizard then guides the user through a complete recovery in a matter of minutes. Furthermore, large files on OS partitions, like temporary page files and hibernation files, are automatically skipped because they cannot be re-used after a restore, and therefore would be a waste of both time and space to back up.
The disk blocks that are backed up are automatically compressed before being written to the backup target location. The idea behind "smart" image technology is to back up only the absolute minimum necessary during a block level backup of a partition or disk. When invoked during a backup, each block is encrypted during the process of reading the data for writing to the backup device.
SPEED Image backup and restores can provide performance speed at or near manufacturer device rates because the technology bypasses the OS and does direct reads and writes to disk. While this allows backups to run faster on an active system, it significantly increases disaster recovery restore speeds because UBDR does not have to negotiate with an active OS partition during a recovery. UltraCopy is an optional utility that provides the ability to copy or move online disk backups to tape.
Clients performing multiple concurrent "push" image backups can use UltraCopy to copy, or move, all separate backups to tape with a consolidated index written to the media. Only use this kind of repair as a last resort. Although the domain controller may start and may appear to function correctly after the repair, its state is unsupported because the data that is deleted from the database can cause any number of problems that may not surface until later.
There's no way to determine what data was deleted when the database was repaired. As soon as possible after the repair, you must rebuild the domain to return Active Directory to a supported configuration.
If you only use the offline defragmentation or semantic database analysis methods that are referenced in this article, you don't have to rebuild the domain controller afterward.
Before you perform a lossy repair, contact Microsoft Product Support Services to confirm that you've reviewed all possible recovery options and to verify that the database truly is in an unrecoverable state. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:. Contact Microsoft Support. On a Windows Server-based domain controller, use Ntdsutil to recover the Active Directory database.
To do this, type ntdsutil files repair at a command prompt in Directory Service Restore Mode. To perform a lossy repair of a Windows Server based domain controller, use the Esentutl.
After the repair operation is complete, rename the. If you can start the domain controller in normal mode after the repair, migrate relevant Active Directory objects to a new forest as soon as possible.
Because this lossy repair method fixes corruption by deleting data, it can cause later problems that are extremely difficult to troubleshoot. At the first opportunity after the repair, you must rebuild the domain to bring Active Directory back to a supported configuration.
ADMT can migrate user accounts, computer accounts, and security groups with or without the security identifier SID history. ADMT also migrates user profiles. To obtain this white paper, visit the following Microsoft Web site:. You can use Ldifde to export and import many types of objects from the damaged domain to the new domain. These objects include user accounts, computer accounts, security groups, organization units, Active Directory sites, subnets, and site links.
Ldifde can't migrate the SID history. Ldifde is part of Windows Server and Windows Server For more information about how to use Ldifde, click the following article number to view the article in the Microsoft Knowledge Base:. Cloud Computing Services. After the recovery, evaluate your current backup plan to make sure that you have scheduled system state backups frequently enough. Schedule system state backups at least every day, or after every significant change.
Select Log on as: Local System Account A reboot may be necessary, if the services do not start on the server. From the Restore Selections tab, select all sets of backups that contain logical drives on the hard disk. For the incremental backups select the Full and all the subsequent incremental backups. If differential backup sets are to be restored, select only the last differential set. It is equally important that if the log files for either Microsoft SQL Server or Microsoft Exchange had been moved to another location during the previous installation of Small Business server, that these log file directories not be restored as well.
The data files have been restored, except those protected by Backup Exec database agents. It is important that your Microsoft SQL Server instance be configured as it was before the disaster. Verify that the setup of Microsoft SQL Server completed successfully by launching SQL Enterprise Manager by registering the newly installed instance and browsing the nodes underneath the instance 4. Once SQL has been installed, the master database will be the first database to be restored from the backup 5.
This is performed so the master database is started in Single User mode. Click the Start button located on the General tab, and then click OK 9. Once the master database has been successfully restored, the remainder of the databases can be restored Refer to the Related Documents section at the end of this document for more information on restoring databases for SQL.
Note: Transaction logs that are present on the system before the databases are restored may interfere with the recovery process and prevent the database from being mounted after the recovery. Subsequently, log file directories that may have existed will also need to be deleted.
Set the Backup Exec services to Manual in the Services applet. This is necessary to have Backup Exec not claim exclusive control to the file mapi Reboot the server. It is normal for the Backup Exec services to not start after reboot since the Backup Exec services were set to Manual in the step above 4. There will also be multiple prompts indicating that files to be copied already exist and are newer than those being transferred from the CD.
Click No to All to retain the newer files. Click OK at the prompt and reboot the server now From the Services applet, verify if the Microsoft Exchange services are started and if they are not, attempt to start them.
Reboot the server only if the Exchange services will not start. Verify with Exchange System Manager that all the Information Store databases in all Storage Groups are dismounted and also set to be overwritten by restores on the Database tab of the Properties dialog of each individual store Change the startup type of the Backup Exec services to Automatic mode and then start the services. Open the Backup Exec console. Select all subsequent incremental storage group backups. If differential backups are to be restored, only the most recent differential storage group backups need to be selected.
Click the Exchange tab, and clear the No Loss Restore selection Enter a location where the associated log and patch files are to be kept until the database is restored in the field Temporary location for log and patch files.
After the database is restored, the log and patch files in the temporary location are applied to the database, and then the current log files are applied.
