You can store data in files, in Git, or in a database.

Sputnik uses an abstract API over several versioned storage solutions. See Concepts.

The default option is to store the nodes in files organized into directories. Alternatively, the following options are available:

• Database
• Git

The following options are under construction (check our code repository)

• Subversion

And you can of course implement your own. Ask on the mailing list.
