Backup and retrieve data from BLT

Beyond the nice topology graph you may need to take snapshots of your IGP DB, or even use BLT as a building block for a third party application.

In order to take snapshots of nodes stored in BLT, you only need to backup the "blt-data.xml" file located in your rundir.

If you want a comprehensive backup of all data stored in BLT, a basic knowledge of the embedded RESTfull API is usefull.

You can use Postman and the following collection to have a full view of primitives availables in BLT :
