You're probably thinking of this message from Linus in 2001:

Dump was a stupid
program in the first place. Leave it behind."
Ok, that might have been the thing that lead me to believe this.
Thanks for tracking that down.
Now the $1.97 question. What's the general take on this statement? Do
we think the dump/restore pair are headed for the pasture (or maybe
already there) or should we assume they're safe to use and won't cost
us our data?
Opinions?
Curtis Preston's original backup book had an detailed appendix on the
posibilities of losing files with dump/restore, and the conclusion was
quite favorable to the ancient program. He has a new book on this topic
which I have not seen "Backup and Recovery", also from O'Reilly, which has
a chapter "Limitations of Dump and Restore". Can someone who has seen it
comment? Has he changed his mind?
I believe you are much more likely to lose files from user error than any
of the theoretical problems complained about dump/restore, so the user
interface is probably much more significant than anything else.
