Tarsnap deduplicates an archive which is being created against the data
in all *currently existing* archives.  This includes truncated archives
which are created from checkpoints if tarsnap fails (because once the
checkpoint is recovered, it forms an archive just like any other) but
does not include archives which have failed (because if you don't have
a checkpoint to recover from, a partial upload is useless and will be
thrown away).

Not at all.  I'm an Emeritus *FreeBSD Security Officer*.  In fact, I
stepped down from that position a couple years ago specifically so that
I could spend more time on Tarsnap.  Tarsnap is here to stay. :-)
