The problem is that if I add a simple tag to a photo, the file will be modified. As a result, I will have to re-upload it next time I backup my photos folder. When doing that on 100+ photos, each one more than 4 MB, it makes a lot of data to upload just for a tag. It would make more sense to only upload the modified database (a few kB). (I know rsync and unison have very efficient algorithms to only transfer the modified part of a file -- but when doing version control, this still causes troubles because neither Git nor any other VCS that I know of is capable of efficiently storing multiple version of binary files -- they just keep full copies for every version, which costs a lot of disk space) Right now I disabled saving tags to photos, so I can in fact already do that. But just to be consistent I'd like to remove the tags from my other photos. > Note that all digital pictures have such data for the date taken and > so on. Of course, and they are much appreciated :) I'd only want to remove what was added by Shotwell, i.e. tags and titles.
