We're using bacula for backing up ~20 servers and VMs onto an LTO5 tape library. While it might be difficult to set up initially, that setup has now been running for over ten years (modulo changes accomodating new hardware). It does provide lots of flexibility, though, you can restrict who gets to restore which files onto which servers, for example, or the ability to backup to different targets. Regarding clock sync, that hasn't been a problem for ages: “Note, on versions 1.33 or greater Bacula automatically makes the necessary adjustments to the time between the server and the client so that the times Bacula uses are synchronized.”
