Although some of the aspects of using dump/restore are a little clunky, it is still superior to any other method of backing up whole file systems. One of its weaknesses is that it will only back up a file system and not a subset of one such as one directory tree. You can, though, restore individual files and directory trees easily. What dump gets you is a system that knows how to handle every type of file condition correctly. None of the other quite do that. Its other weakness is that it is filesystem/OS specific. Geneally, you cannot take a dump on one OS and restore it under a different on - like you cannot dump SunOS and restore on FreeBSD or whatever. It will work over networks, though that can be slow and it doesn't recover well from network errors/failures. ////jerry > > -- John > > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
