I've added the archive image settings to the camera MEDM, and updated the INI files to make it work. Currently, the archiving on all cameras is disabled by setting the interval to 0. To enable archiving, set this value to 60 to save an archive image every hour (do not use a value less than this without good reason - we don't have infinite amounts of disk space available). Archive images are saved to /ligo/data/camera/archive/YYYY/MM/DD when enabled.
Thank you Cyrus!
I've set the interval for most of the usefull cameras to 1 hour, if this is taking up too much space, let us know.
