use mutt, then the de-duplication business boils down to typing 'D~=' in 
each folder (this does message-id based de-duplication, but that should 
be good enough).

i'm not entirely clear on what fate you intend for the backup. if you 
want to "replenish" your active primary account, then first make an 
isync clone of it (if you have none yet) and then move the mails from 
the backups into the clone (but make sure to strip the ,U=xxx infixes 
from the filenames first - this should be easy using `file-rename` 
(package 'rename' on debian) or krename). after the de-dupe, you can 
just isync --push the clone and you're done.
