Re: Backup and Restore of Realpresence Group Series 500..
#1, see the GS Admin guide. The factory restore is via hardware using the reset button.
#2, There is currently no utility to back up 100% of the configuration. Please refer to the Admin Guide and see Profiles for information on what can be backed up. See "Manage System Profiles with the Web Interface"
To request functionality beyond the currently defined functionality please work with your Polycom SE and have them open a feature request on your behalf.
