There was a time when Time Machine was pretty good. But Apple became increasingly parochial about TB backups such that you cannot cull them even with root access. Any culling must be done with the TM app from the original machine that owned the files. This makes it impossible to be the sysadmin for your family's backups. Now I use Carbon Copy Cloner, Syncthing, and Arq. My family's backups are quicker, more seamless and much easier to administer as a result.
