It depends. If you are just writing some small subset of files from a filesystem (e.g. your home directory) then tar would do. If you want to back up your machine, and the tape drive is big enough, then use dump. Both have good manual pages. Confusingly, FreeBSD has two versions of "tar" and which one is the default "tar" has changed recently. For simple stuff, they will be compatible with each other. bsdtar : bsd derived version of tar which in theory will know about filesystem flags, but if you don't use them then it won't matter. Also seems to mess up if the archive you write is compressed but happens to be empty (might be fixed by now). gtar or gnu tar : GNU GPL version of tar. This is the tar you get on Linux, for example. Won't know anything about specific FreeBSD filesystem things like flags. Other options include cpio (a bit like tar) or specialist backup software like bacula which you'll find in the ports. I can't comment either since I've never used them. You're still very vague about what you want to do; with more specific information better advice might be possible. E.g. "I want to backup up my home directory and email files every day"; or "I have four 80Gb disks which I need to back up to a 40Gb compressing tape drive, what should I use?". --Alex
