You've got some excellent pe[a]rls of wisdom, may I give some
advice less specific to perl?
1. Make the (pre-mount) mount point not-writable,
so that you can only write to it when mounted.
This would only work for non-root, since root
can write anywhere.
2. Backup to a _subdirectory_ of the mounted filesystem.
This way you can check the return code of cd or
easily check for the existance of a directory.
idiomatic shell code for copy via tar:
tar cf - /stuff/to/backup | ( cd /place/to/backup/to && tar xf - )
The vital bit here is the && which says to only do the tar xf if
the cd succeeded.
