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.
