[NTLUG:Discuss] backing up in linux....

[Eric Waguespack]

man chattr
..
A file with the 'd' attribute set is not candidate for backup when the
dump(8) program is run.

this is really no different than backing up data to multiple floppy
disks or tapes in the old days... they need to each have a subset of
the original files, retaining the original directory structure.
