[Borgbackup] What to do if file is lost?

[Tomasz Melcer]

Hi,

My storage for backups developed a bad block (found using `btrfs 
scrub`). I made a copy of everything, except for one file that seem to 
be hit by badblock (an index.«some number») file. The original medium 
still seems to work fine—I mean, if not for `btrfs scrub`, I wouldn't 
know about the problem.

Given that the archive is pretty large now, I wonder whether there is 
any way to regenerate this file safely? At this point I wouldn't mind 
running a full backup run from scratch, but it would save a lot of time.
