Best Practices for recovering corrupt ext2/3 filesystems

Hi All,

I am writing a document on Best Practices for recovering corrupt ext2/3 filesystems. The documents start with recommending scheduling backup of partition tables and filesystem images created with e2image. I was hopeing that the subscribers of this list might be able to verify some things for me.

Would it be safe to say that fsck would fail to recover a filesystem if the following information from dumpe2fs on the filesystem and the filesystem image differs:

Inode count:              

Block count:              

Reserved block count:     

Block size:               
Group x: (Blocks Y-Z)

Are there any other entries that would categorize as "cannot differ" entries?
