Yes. Use dump(8) -- that's what it's for. It reads the inodes,
directories, and files directly from the disk device, thereby
eliminating stat() overhead entirely.
Any replication mechanism -- rsync, tar, even dd -- can be used
as a backup mechanism, but dump was specifically designed for the
purpose.
