This is going to vary depending on what exact data is corrupt/missing.
If it's the Image Metadata(postmeta), then that's the only thing that ties
an upload file to a attachment post - You might be able to reverse-engineer
it based on year&month of the attachment, and it's sanitized name..

If it's the above case, i'd do something akin to this:
foreach file in folders
   if is a resized filename; Delete it, continue.
   get month and year from folder names
   get sanitized filename from filename
   Search for attachments which match this; if none found, add it to the
manual list
   If a match was found, run the WordPress generate metadata code for that
Attachment ID and filename.. (Note: I'm not sure how it's going to handle
running on already existing attachments, etc) - That should re-generate the
thumbnails and add all the correct metadata

Of course.. The clients backup service is where this should come into play..
restore the Database.. If they don't have a backup service from their host,
consider setting up a database backup nightly to a off-server location, or
invest in a VaultPress account (or similar if there are any competing
services out yet)
