Another 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
