-A handy alternative to the default [[backend|backends]] is the
-SHA1 backend. This backend provides more git-style assurance that your data
-has not been damaged. And the checksum means that when you add the same
-content to the annex twice, only one copy need be stored in the backend.
-
-The only reason it's not the default is that it needs to checksum
-files when they're added to the annex, and this can slow things down
-significantly for really big files. To make SHA1 the default, just
-add something like this to `.gitattributes`:
-
-	* annex.backend=SHA1
