Restoring Areca Backups

The first step to restoring an Areca backup image is to map the network drives as they were on the computer you made the backup from (if you were using network drives to store the backup).  If you can't remember how the network drives were initially configured or mapped, proceed to the next step, and Areca will eventually tell you which drive is missing.  Once the drives have been remapped as before, and if the backup file is no longer stored on that mapped drive, copy your Areca backup folder (for example, in my case, the folder named 1878606550) to the backup drive location.   

In order to restore an Areca backup archive onto another computer, you need to copy the bcfg file located in the areca_config_backup folder to the Areca workspace directory on the computer you're attempting to restore the files on.  Once you've done that, you can restart Areca, and you'll be prompted to provide the encryption key.  Enter it here.

Assuming the drives exist as they did on the previous computer and the backup folder exists where the backups were being stored, you should be able to view the files within the Archives tab.  Right click on the backup and choose "Recover".  Follow this wizard, and the files will be unencrypted and extracted.

Getting Areca Backup to Work on Modern Systems

Unfortunately, Areca Backup hasn't been updated since 2015.  But, it still works great, and it's an awesome program that can compress and encrypt files into a backup archive that can be transferred to a NAS drive or uploaded to the cloud.  However, getting it to work on a modern system can be a chore.  After installing Areca Backup, when you try to launch the application, if nothing happens, you will need to perform both of the following fixes:

Install 32-bit Java first [Windows Offline], and then install 64-bit Java second [Windows Offline (64-bit)] if you have a 64-bit operating system.  Without the 64-bit version of Java, Areca will not launch on a 64-bit system.

The next step to getting Areca to run is to replace the "swt.jar" file in the lib folder found in the installation directory (default is C:\Program Files (x86)\Areca\) with this one:

Once the original swt.jar file has been replaced in C:\Program Files (x86)\Areca\lib with the one linked above, Areca will now open and run properly.

Tested on Windows 7 x64, Windows 10 x64, and Windows 11 x64.
