Given Cycliq’s tech support recommendation to never, ever delete files from the camera’s MicroSD card, I’m now copying the files to the 500 GB network drive thusly:

rsync -au --progress /media/ed/Fly6 /mnt/video/

The Fly6 saws off a 400-800 MB file every 10.000 minutes, so a typical ride produces 4 GB of data.

The Sony HDR-AS30V emits a 4.2 GB file every 22:43 minutes: call it 12 GB per ride.

Somewhat to my surprise, both copy operations can proceed concurrently at 4 MB/s apiece. For unknown reasons, the drive doesn’t record the creation times for any data files:

ll /mnt/video/Fly6/DCIM/10450608/
total 4.2G

The directories generally have the right dates, though, so maybe I’ve screwed up an obscure Samba / CIFS settings. The diratime option should be turned on by default.
