One of my coworkers recently lost a single loose tree object.
We suspect his Windows virus scanner deleted the file. :-(
Copying the one bad object from another repository immediately fixed
the breakage caused, but it was very annoying to not be able to run a
"git fetch --missing-objects" or some such. Fortunately it was just
the one object and it was also still loose in another repository.
scp was handy. :-)
