Normally you restore via the installation stage of the MSL. (console) One of the last things it asks is whether you're restoring a backup.When restoring the existing databases are deleted and a restore is done.Login to the console (SSH) as admin. Scroll down the options towards the bottom and your restore backup is there. The system will delete the database and reboot to restore the system.It is in the troubleshooting section under Database Recovery (Restore) from the I&M Documentation.http://edocs.mitel.com/UG/Apps-Solutions/MiCollab%208.1/MiCollab/MAS_I&M_MiVB_R8.1.pdf
