Top Forums UNIX for Dummies Questions & Answers disaster recover w/tar & find Post 31806 by Neo on Wednesday 13th of November 2002 03:14:29 PM

I'm very interested in the original posters question of why find|cpio restores without corruption LILO as does tar (seemingly).

From your post, it would seem that one corrupts (or indirectly influences the corruption or lack of something) of either the Master Boot Record (MBR) or the LILO boot maps.

If we assume that both find|cpio and tar archive and restore the LILO configurations files in the LILO configuration directory, then a logical (but wrong, me thinks) assumption is un-tar corrupts the MBR, and that does not seem possible.

The premise of the question is very interesting and has me contemplating how we could uncover the problem.??.. OR, if there is someother factor that is causing the LILO error unrelated to either find|cpio or tar.
