Thank you for wanting to add lzip support to Duplicati! I think the official recommendation would be .tlz based on the fact that there are actually references to .tlz in the lzip manual; however, if there is any chance your software could add .tar.lz instead, that would be quite advantageous; alternatively, perhaps you could use "lzip -l *.tlz" and pipe the output into a check to make sure they are all lzip archives in contrast to plain LZMA.
