#since the delete spanned drives a bunch of files were unrecoverable

#this script will pull in files from a cold storage mount and restore the files
#snapraid has labeled as unrecoverable.  Running a snsapraid fix after this will
#also allow you to recover even more files through snapraid since the ones
#this recovers will no longer be missing.

#you could rsync the entire drive but then that would also restore files you deleted
#this will only restore files that are actually missing
