I can help with nodump... man 2 chflags contains UF_NODUMP Do not dump the file. and dump(8) has an -h flag to respect the nodump flag. Basically, if you use -h0 when calling dump, then files that have the nodump flag (and everything under a dir that has the nodump flag) will be omitted from the backup.
