I am wondering if there is a simple solution to backup/restore the inode
table (the relation "inode <-> filename").

With "ls -aliR" I get a list which I am now saving every few days.
The parameter "-i" displays the inode, that I can reconstruct the
filename from the inode, if this garbling error occurs a second time.

The reconstruction process probably would be a simple "grep | cut" thing.

Is there perhaps a finished script doing exactly this? Or any other ideas?
