Hi Arthur,
Deduplication is tied to each machine key.
If you have multiple machines using the same key, then data will
be deduplicated between all those systems [1]. If you have
multiple machine keys, then there will be no deduplication between
them.
[1] If you are sharing a machine key, then
If you are using the same key from the previous machine then they may be
de-duped as the commmand you are running has access to the previous
archives.
Each key is unique in a way that it should never have access to another
machines data.
Make sense ?

Does tarsnap's de-dup work on one machine at a time or across all
machines in an account?
The reason I ask is because I've moved a largish mail archive from one
machine to another and am unsure whether the backup on the new machine
will reuse the blocks from the old one, or whether I'll end up
