Hi Mark, 

As you have probably read the backup files restore the postgreSQL database as of a certain moment of time. 

The files themselves are in C:\ProgramData\AimmsPRO\Backup on the PRO host. 

You can perform a restore from the PRO configurator, tab Backup Management. 

In the Backups from current version of AIMMS PRO Platform section mark the line with the bakup you would like to restore and click the Restore Now button. 

When the restore is completed you should see a pop up message saying that the restore was successful. 

Note: The version of the restored file needs to be the same version as the current version of AIMMS PRO, otherwise the restore will fail. 

If you have any issues during or after restore, please contact support@aimms.com since you will most probably need to share logs.
