OpenTaco comes with built in versioning for units. Right now we do simple version history, keeping the whole version of each document rather than implementing a diff system. You can configure how many versions are kept with the configurable environment variable OPENTACO_MAX_VERSIONS. By default we store 10 versions. Version operations respect unit locks.

​
List Versions

You can list the versions for a unit with the command taco unit versions <unit-id> List Versions

​
Restore a past version

You can then restore a version from this list by using the version number rather than the hash with taco unit restore <unit-id> <version-number> List Versions
