I manually created the /opt/rtcds/caltech/c1/burt/autoburt/snapshots/2018/ directory. Maybe this fixes the hickup? Gotta wait about 30 minutes.
It worked. The first backup of the year is now from Wednesday, 01/10/18 at 15:19. Ten days of automatic backups are missing. Up until 2204 the year folders had been pre-emptively created so why was 2018 missing?
gautam: this is a bit suspect still - the snapshot file for c1auxex at least seemed to be too light on channels recorded. this was before any c1auxex switching. to be investigated.
