Yes, I understand, it will work. But, if case of any error (even our 
fault : premature end of script, for example) you can still end up with 
attachement forever lost on the filesystem.

Right, it SHOULD not happen, and it probably won't represent a big 
volume. But Still, it could happen under specific circonstances. In that 
case, I don't see any simple way to detect that kind of files ?

Do you see how a script could detect some orphaned links ??

For the archiving, good idea to use dsync, thanks for your answer.
