Unitrends Disaster Recovery Guide

It has been an on-going effort to construct what I refer to as “Quick Reference Restore Guides” for myself and especially my co-workers. I’ve refined the helpful, but ultimately bland Unitrends Admin Guide into what I consider to be a streamlined guide chocked full of helpful Screenshots. Below you will find the various “Quick Reference” Restore Guides that I’ve compiled for Unitrends’ Various restore processes. Please comment below with your thoughts, suggestions & feedback  – Thank you.

I’ve spent a good deal of time creating and refining The below guides and Hope that you find them a helpful addition to your Unitrends Disaster Recovery Kit. Even though I pride myself on being very detailed and accurate in my Guides, I urge everyone to go through each Restore Scenario below and become familiar and comfortable with performing each one – Because not being able to perform in a DR Scenario could quite literally cost you your job! Luckily for us though, Unitrends has a wonderful support team should you ever need it. Simply Click the small Arrows Below to Expand your chosen Guide to get started.

Baremetal Restore

Baremetal Restore

Creating a Baremetal Iso

– Login to Any available Server with Baremetal Media Client install
Start > All Programs > Unitrends > Baremetal Media


1.) Verify the System name & IP address of your DPU
2.)  Select D2DBackups in the Dropdown
3.)  Select the Desired Client and verify Networking Info
4.)  Change Save location & Rename ISO file if desired
5.)  Create ISO
6.)  During the ISO creation process, you will be prompted to inject any additional Drivers.


7.)  Select Yes if previous attempts at creating a Bootable BareMetal ISO failed due to driver errors, Otherwise click NO to finish.
             *Typical Driver Failure occurs when a NIC / Chipset / Mass Storage Driver is missing, incompatible or corrupt.


Troubleshooting Driver Errors:

When Restoring to dis-similar Hardware or sometimes even similar hardware, You may receive a failure notification during Boot from the .ISO saying that the Boot environment could not detect a NIC card or Hard drive. In a raid environment, the restore may complete successfully but crash on Boot up. In this Case you can boot to the .ISO image once more and do a driver injection for the mass storage driver.



When Injecting Drivers via BareMetal Media

Download The appropriate Hardware Drivers, Then Extract the Contents.
( Ex – C:\temp\whdservmon Drivers)



*Browse to the Extracted Directory and Select the appropriate .inf File / Files

*You can Use View to read more information about the driver

*Add > Continue



Additional Info

*You can Inject Mass Storage / Raid Drivers Directly from the Baremetal ISO Menu (you do need to Re-image to inject drivers )


*The Unitrends Additional Drivers Window will tell you which drivers to use




Starting the Baremetal Recovery Process

*Burn the .ISO to a CD / DVD

*Boot to CD from the Replacement Server ( F12 at startup )

*CD will Boot to Windows Baremetal Recovery GUI


*Select Baremetal Restore > Then Follow On-screen Menu options to Execute!

*You can Use the Real-time Statistics To monitor Restore Progress.

*When Complete – Diagnostic Tools > Restart PC.

Exchange Restores

Exchange Restore Guide

– Login to your Unitrends DPU

– Select a Exchange Server you wish to run the Restore from on the left Navigation Paneand then hit “Restore


– Select a Date and Time that you wish to restore from.


Restoring a Storage Group to an Exchange Server

– Select Exchange_Restore3

– Select Which recovery Method you would like to use:

            -Restore to an Exchange Server

            -Restore to an Alternate Location

– Choose the exchange Server you would like to restore to, or if restoring to an alternatelocation, Choose where on the target Server you would like to restore the Storage group.

*** Please see instructions located in the Unitrends Admin Guide for an in-depth overview of this process, Thisis Mandatory if it is your first time performing this function


Restoring to Exchange server VS. Alternative location

-While both methods will work, Unitrends suggests restoring directly to the exchangeserver if possible. Restoring directly to an exchange server serves 2 important purposes – The Unitrends restore process will automatically place the associated log files and mail stores in the appropriate location, and automatically clear the .chk file – kick starting the merge process for log files and backup.

-Once the restore is complete, the unitrends restore process will delete the “E00.chk” file in each mail store, this is a flag that exchange utilizes to write logs – when deleted it will force exchange to read any outstanding log files and merge them into the restore. (Note:  during this process the Exchange server may appear to be frozen / hung up – you can     view the progress of processing the log files by comparing the log file directory with the Event viewer logs which will detail each log file it reads during the mounting process )

-If you choose to restore to an alternative location, and move the log files and mail stores to another exchange server – you will have to manually select the appropriate log files to roll into the mail store, delete the .chk file, and mount the Mail-stores in order to kick-start the process.

***Important to Note:

– Timestamps for  EDB / STM files will typically represent the date that the initial Master backup was taken, as Unitrends does not update the timestamp for these files.  They will not match the date of the Master / Differential backup!

-Unitrends does not purge log files after a Full backup is ran, it simply triggers exchange to do that job. As a result, Unitrends will restore all log files betweenFull Backups.

Restoring Individual Mailboxes

– Select Exchange_Restore4

– In order to start the restore process you will have to “Mount” the backup by hitting the  Exchange_Restore5 button. You can then use the Exchange_Restore6 key to monitor the Progress of  Mounting the Data Store

– Once it has been mounted, You will want to do the Following to access individual Mailboxes and Mail items:

– Remote into the PC / Server that has Kroll installed on it.

– Map a Network drive to “ \\Yourdpu\Exchange_Restore\

– Open Kroll On-Track Power Controls


– Follow the prompts in Kroll as Follows:


-Keep the “Run on Startup” Checked , and Click Next


– Click “Browse” under “Source File” and Browse to the Mapped Network Drive you created and select the Database that you would like to see. Click Next

***If you are restoring from a Differential Backup, You will want to browse to the “merged” folder instead of “BackupX”. Differential Restores take substantially   longer than Restores from an Exchange Full backup, because they have to compile all the log files. Only Restore from a differential backup if you HAVE TO.


-In most Cases you will want to select PST File. Select Where you would like to save the  PST File, and then click Next

– When Finished Loading, Click Finish

– Click Export and follow the prompts to Export to a PST File.



To Export the Mailbox to an Exchange Server…

***For this step, Make sure you are logged in as a domain admin, or simply do a        “run as” for Kroll. Otherwise you will not be able to access the Exchange Server.

– File > Open\Create Target > Open Target Exchange Server


– Enter your desired Exchange server, and keep the rest of the Settings as shown below.


-Once Kroll Loads the Target Mailboxes, You can simply Drag and Drop Mailboxesbetween the Source and Target areas of Krolls Interface.


***For Advanced Features, and first time users – Please reference Below.
