I notice the option for "Inventory Backup" in Inventory Tools is turned off. How should I go about doing an IAR inventory backup? Is there a preferred Metro way or should I just run it from a system terminal?
If you have a region on an own OpenSim server, then the easiest and most efficient way is to use the own OpenSim console for the IAR backup. If you have rented the region(s) on another server - or no regions at all - you need the help of the grid admins. Theoretically, the persons who run the region servers could do it, but then those would need your account passwort.

on a rented region (rented from Metro i.e.) you can use our "METROPOLIS OAR-MANAGER" to create OAR and IAR backups or to upload such files. The link to it and your user credentials are send to you with the confirmation of the setup of you region.
