The point I was trying to make is that the way to make the most accurate backup is to use the tools native to the filesystem. To the best of my knowledge, only UFS and ZFS actually supports the flags used by chflags(2), and since I don't use ZFS, I used UFS as my example, which means dump/restore. For ZFS you could use 'zfs send' on a snapshot. > Unless I'm missing smth dump(8)/restore(8) don't work on ZFS.

See libarchive-formats(5). If you are sure that your filesystem is not using any features that cannot be stored in the libarchive format of your choosing, then by all means, go ahead.
