Restic works very well for me, and I've successfully used it to restore lost files. The one issue I've encountered with it: it uses a lot of memory, proportional to the size of the repository indexes, so if you're backing up a lot of data on a machine without a lot of RAM (such as a virtual server), you may run out of memory. Setting GOGC=20 can help slightly, but ultimately, restic needs fixing to support working on indexes larger than memory.
