If I use the export function to back up my pictures I'd like to back up all versions, so that I can recover the original, the one I like most and is set for viewing, and any other variants (I have many pictures with 'variants').

Today only the version set to be viewed is exported, so that for a real back-up to take place I have to copy the actual directory (and even so, if I really lost my pictures, I wouldn't be able to get F-Spot to reintegrate the versions in its DB I think).

It would make sense to integrate this into the export, or to have another form of export for backup. A feature proposed by someone else makes sense in that context: being able to see which pictures have been exported and which have not.  This would translate into: which pictures, or new/modified variants of pictures should be backed up because they have never been backed up before. A backup feature should allow to back up everything in a given selected range of photos, or everything that has not yet been backed up in a given selected range of photos, or everything that has not yet been backed up in the whole database.

Cheers,
Pierric.
