If I create a backup of the same SD card several times a day, is the entire card copied again each time or does the disk recognise which photos have been added?
Yes, only newer files are copied. This means that a backup can be made quickly, even if the images in the phone/camera are not deleted.
There is back-up software for this, which can be set as required (back-up job).
Always back up everything, only sync new/changed files, etc. ...
