git annex numcopies N
Tells git-annex how many copies it should preserve of files, over all repositories. The default is 1.
Run without a number to get the current value.
This configuration is stored in the git-annex branch, so it will be seen by all clones of the repository.
When git-annex is asked to drop a file, it first verifies that the required number of copies can be satisfied among all the other repositories that have a copy of the file.
This can be overridden on a per-file basis by the annex.numcopies setting in .gitattributes files.
