OpenNebula Enterprise Edition supports Restic as backend for its Virtual Machine (VM) backup system. The current implementation of the Restic driver uses the SFTP storage type and allows tuning of several parameters to perform backups.
Thanks to this integration OpenNebula can perform full and incremental VM backups leveraging all the features offered by Restic like compression, data encryption and deduplication. This integration runs directly through Sunstone, our GUI to manage the administration of your cloud.
You can find more information about the Restic and OpenNebula integration in the official Documentation site.
Zmanda is a commercial offering built on top of fork of restic. Over the last 3 years we have integrated various features of restic backup in to our commercial enterprise backup tool.
We are committed to the open-source community and contribute back to the restic community with innovative features that we have solved for our customers. The features we have contributed to the community include back up of extended attributes, security descriptors in Windows and optimizations to the Azure backend. We also have proposed pull requests for back up of NTFS Alternate Data Streams (ADS), support for SMB as a backend and the concept of incremental backups so that the whole tree is not scanned again.
With the core of restic, we have solved physical back ups for database solutions including Oracle Database using RMAN, MySQL and MariaDB.
You can find more information about Zmanda on the official page talking about our integration on top of Restic.
