Restoring to an alternate location

See the following for details on restoring to an alternate location:

ClosedRequirements for restoring to an alternate location

Restore to Alternate Location allows the Exchange information store to be restored to a location other than the original location where it resided when the backup occurred. The alternate location can be either to the same Exchange Server host, a different Windows protected client, the network share of your Unitrends backup system, or any CIFS/NFS network storage. To restore to CIFS/NFS network storage, you must first add the storage to the Unitrends appliance as a client. For details, see Adding CIFS/NFS clients.

ClosedBackup type details for restore to an alternate location

The following specifies the difference between a full, differential, and incremental restore to an alternate location:

Backup type

Explanation

Full Restore

All of data associated with the Exchange information store is restored to the specified location.

Differential Restore

Only the data contained in the differential backup is restored to the named location; the associated full backup is not restored. A differential restore should be used only if certain files within the backup are required or a third-party tool is used for individual mailbox or item restore, e.g. Kroll On-Track. This type of restore can be performed to any Windows-based protected client and the server is not required to have Microsoft Exchange Server installed. This type of restore may also be done to the backup system itself.

Incremental Restore (version 7.5 and higher)

Incremental backup chains can become very lengthy, creating a large restore. To simplify the restore process, the appliance creates a single restore job on the restore point chosen. For details, see Point-in-time restore. This is not a synthetic backup, it is simply a concentration of the available backups, sent in backed-up order.

ClosedTo restore a database or storage group to an alternate location
1 Verify all prerequisites have been met, as described in Requirements for restoring to an alternate location.
2 Select the Exchange client in the Navigation pane and click Restore.
3 Select a Recovery Point Day from which the backup will be restored by clicking on the calendar. Available days display in bold.
4 Specify a Recovery Point Time by selecting a backup in the list, then click
Next (Select Options).
• To locate the desired database or storage group, hover over the backups in the list. When you hover, the database or storage group displays.
• Restoring a backup restores the database or storage group to a specific point-in-time state. So selecting a differential or incremental backup also restores the associated full backup.

Restore Items performs an individual item restore directly from the Exchange backup and not a complete Exchange restore. For more information concerning restoring individual items, see Restoring Exchange items .

5 On the Restore from Backup of Client page, verify the backup and database/storage group displayed are the ones you wish to restore. If not, click Cancel and choose another backup.
6 Select Restore to Alternate Location.
7 Select a restore target from the Client To Which To Restore list.
• The list contains all protected clients and the backup system itself.
• To restore to CIFS or NFS-configured NAS storage, you must first add the storage to the Unitrends appliance as a client. For details, see Adding CIFS/NFS clients.
8 Enter a target directory.

This is the directory on the target client to which Exchange data will be restored. If you have selected the backup system as the restore target, data is restored to the system’s network share: /backups/samba.

9 If desired, modify these options:
• Check the Preserve Directory Structure box if the directory hierarchy information in the backup must be restored. For example, if you specify the Target Directory as /tmp, all files restored from the backup will be placed into that single directory.
• If the option Overwrite existing Files is selected, existing files will be overwritten during the restore.
• Restore Newer Files Only restores a file only if its date is newer than the existing file on the client. If the file does not exist on the client, the file is restored.
• Set File Dates to Today sets the last modification date of the file to the date and time of the restore.
• The option Unix Text Conversion will not convert new lines to CR-LF when restoring UNIX text files to MS-DOS systems.
10 If desired, run pre- or post- restore commands by selecting Show Advanced Execution Options. Specify the client-side commands to run by entering any system command or user script in the Client Pre-Restore Commands or Client Post-Restore Commands fields. For details, see About backup options.
11 Click Restore. All database and transaction log files are restored to the target directory.
