Correct.

The existing data will be fine. If you use a 1.2 client to restore 1.0  
data, then you will see non-fatal warnings about missing SHA1 hashes,  
but the restore should succeed. The 1.2 version stores file hashes in  
the metadata to verify the files upon restore, but obviously those  
hashes won't be there in metadata written by the 1.0 version.
