This article describes recovering Windows with BSR Pro, introduced in SEP sesam version 4.4.2. SEP sesam BSR Pro is based on O&O DiskImage and fully substitutes the old SEP sesam BSR 2.3 (also known as BSR dissimilar).
To successfully recover your Windows system from a disaster, all preparation steps have to be performed properly. For details, see SEP sesam BSR Pro – Disaster Recovery for Windows.
When recovering your system, you must first restore it from the bootable disk (CD/DVD/USB drive), network share or local space where the ISO image is stored. Only then can you restore the system configuration that was backed up by BSR backup task.
Available disaster recovery methods
- Direct recovery with SEP sesam BSR Pro, option Quick Start
- This is the simplest and the recommended method, suitable for all save sets that are smaller than 120 GB. For recovering save sets that are larger than 120 GB, consider using the alternative 2-step network share recovery (see next item).
- 2-step recovery via network share – manual restore + option Start Restoration
- The recommended method for recovering large save sets (>120 GB). It requires a manual restore of the latest BSR backup image file to a network share before SEP sesam BSR Pro, option Start Restoration is used. This method is advantageous for large system volumes because it allows greater throughput via network share (direct restore throughput is 30-60 GB/h, while the 2-step recovery allows 30-300 GB/h for phase 1 and 100 GB/h for phase 2). Note that the given estimates are only approximate and depend on each individual environment.
To find out more about restoring an image on a computer with different hardware, see O&O DiskImage documentation about M.I.R. (machine independent restoration).
- BSR Pro can only access data that is stored on an ordinary SEP sesam data store (store type Path). If the save sets are stored on tape, you will have to migrate the required data to a SEP sesam data store or restore it to the network share before starting a recovery.
- A BSR Pro bootable disk (CD/DVD/USB drive) or network share with the ISO image must be configured. If several Windows systems were set up with similar configuration, you can use the same bootable disk to recover similar systems.
- If you are restoring your system to dissimilar hardware and any of the drivers is missing, you will have to load the missing drivers manually.
- If you are performing a 2-step recovery via network share, first your BSR backup task must be restored to the network share so that it is available for recovery. It is recommended that you schedule your BSR restore task to run daily after your NEWDAY schedule. For details, see Preparation step for subsequent recovery via network share.
- Before starting the recovery procedure, open a shell on the SEP sesam Server and execute the command below. This command enables you to contact the SEP sesam Server even if the reverse name resolution does not work on the new client.

There are two different methods for restoring a Windows client when using BSR Pro for recovery. The first option, which uses Execute BSR Pro Quick-Start, can be quite time-consuming if restoring large save sets. In such cases it is recommended that you use the second option, Start Restoration. Note that this method requires the image file to be restored to a network share before starting the recovery.
- Insert a boot medium (CD/DVD/USB-stick) in the Windows system you want to recover, or boot over the network from the stored ISO image.
- If any of the required drivers are missing, load them manually (pay special attention to the network driver.)
- Make sure that the network is correctly configured. Then start the SEP sesam BSR Pro application.
- If neither the hosts file nor DNS are being used, you have to address the SEP sesam Server via its IP address. Start SEP sesam BSR Pro and click the settings icon at the top-right corner of the BSR Pro window. Switch to the Security tab, click Edit and then modify the settings of the Network path/server by inserting the SEP sesam Server's IP address.
- Follow one of the procedures below based on which option you select. Note that the Start Restoration option requires additional preparation step before starting the recovery.
- In the SEP sesam BSR Pro, click Start Restoration. Browse for your image file and select it.
- In the Drive Restoration window, select the whole disk, then select the target drive. Click Start drive restoration to begin the restoration.
- To set additional options, click More options. The option Then adapt the different hardware (M.I.R) adapts the operating system to a different hardware platform and should only be selected if you want to use different hardware. To find out more about restoring an image on a computer with different hardware, see O&O DiskImage documentation about M.I.R..
- Select Completely delete target drive.
- Remove the device with your ISO file (USB drive, CD or DVD) from the client and restart SEP sesam.
- Restore your client's data from the full backup.
Option: Execute BSR Pro Quick-StartIn the SEP sesam BSR Pro, click Execute BSR Pro Quick-Start. In the BSR Quick Start window, select the client you want to recover and the source save set for recovery. Click OK.
