BDRSuite Backup & Replication - Vembu Backup

We use the BDRSuite Backup & Replication Vembu Backup to protect our virtualized environment in a clustered Hyper-V setup. In our experience, the software's restoration options are very poor and not intuitive. Some restorations have never been completed, despite running for many hours. File restoration on an NFS simply does not even open the protected content. For us, backup jobs are slow and fail to complete most of the time. In our experience, the space used by the generated backups consumes a lot of space, and the cleanup of old data does not happen most of the time, requiring manual deletion - which is also very difficult to do. I do not recommend using this tool.
