TungstenFabric (formely OpenContrail, the opensource version of Contrail by Juniper Networks) is one of the most established SDN solutions on the market today. At Cloudwatt, the SDN features of TungstenFabric provide the networking features of our IaaS offer. TungstenFabric allows us to provide virtual private networks, security groups and also more advanced features such as SNAT and LBaaS. We have been using OpenContrail ever since 2014 (using version 1.6 back then) and over time have also made some upstream contributions.

The OpenStack community’s overview on this feature.
How it works ?
When you make an incremental backup, only the difference with the last increment is stored, you optimize your storage needs and profite from a better backup performance.
The feature is available using the option
--incremental in CLI - through API Volume V2 only.
To make an incremental backup of a volume, a classic backup is required. The Volume service retrieve all available backup for a volume, and will make an incremental backup, based upon the last created backup (which can be an increment or not). And so on.
A backup which is used to make an incremental backup can’t be deleted.
To know if a backup is incremental or if a backup has multiple incremental backups, you can use
cinder backup-show command.
We encourage you to make an incremental backup as soon as you have made changes to your volume: the more incremental backups are made, the more efficient the operation will be.
To avoid a chain of incremental backups, which can not be deleted, we strongly advise you to do a normal backup every 5 to 10 iterations.
If you wheel to use this feature, an adjustment of you quotas is maybe needed : default quotas are not scoped for this feature.
