Is there any way to fix this other than completely repeating the copy?
I'm sure there are other ways, but the first things that comes to mind
is touch. Or rather a script that uses touch, and possibly find or a
recursive glob. The idea being to have the list of files in (either of)
the directories and touch the new copy with the old copy as the date &
timestamp reference.
touch --reference=${OldPath}/${CurrentFile} ${NewPath}/${CurrentFile}
I'd probably cd to the new copy's path and do the recursive find / glob
there to get the file name in a variable. I think that would apply more
of the directory traversal walk I/O on the new path and just reference
the full path to files in the old path.
Quick testing (of globing, namely "**/*") in Zsh makes me think that the
following would come close.
OldPath="/mnt/old"
NewPath="/mnt/new"
cd $NewPath
for CurrentFile in **/*; do
touch --reference=${OldPath}/${NewPath} ${NewPath}/${CurrentFile}
done
Will some version of rsync do what I want?
Maybe ~> probably.
Thanks for any suggestions, other than to think more carefully before
typing.
Mistakes happen. Once you realize how to recover from something, you
become less scared of doing it. Save for your time to actually do the
recovery.
