So far we have tested the backups, add-on based backups and VM-based backups, as well as snapshot-based backups. We have done restores, file-server backups, and object-based restoring. We have done database backups as well.
DR is the most important thing. For other things it seems comparable to other backup solutions, but right now, we do not have any DR site. Using this, we are planning to set up DR.
