Rubrik’s presentation seems to be impressing a lot of people. One of their biggest features is their ability to distribute backup data across various rack mounted “Brik” appliances, with easy scale out provisioning. Mike Preston has a writeup going into some of the secret sauce that let’s Rubrik do this: the Atlas File System. One of the most interesting features is how the system is able to deal with failure. The file system is able to do replication on both a node or drive level. This allows the overall system to have a whole node or up to two drives fail without any danger of data loss. Mike goes into a deep dive on all of the technical details, so make sure to check it out.
