My read of that is chattr(1) is good for one OS (variant), and
ony one of the filesystem types the OS variant supports.

"classic" dump programs used the last modification time on the
inode, along with a timestamp of the last dump at a given level,
to determine if a file should be placed on the dump media.

Additionally, dump file formats are typically OS, and file
system, specific, and thus not very portable.
