Really, I don't recall such restrictions, but it's been a very long time so
I'll just blame my memory.  fsck.vfat mentions fixing quite a few things.

As mentioned, that's the theory, if everything is perfect.  Alas the real
world means that block numbers, contents, messages, drivers, etc during an
issue (like a power supply failure, brownout) or even just a driver bug.  It
could even be something as subtle as a vibration.

Sure, rsync, backups, version control etc.  The way I do things like this is:
* Email keep it on server, backup the server (backuppc in my cse)
* source code remote subversion server (again backed up by backuppc)
* Important non-source code related files rsync

The rest... when it dies I consider it house cleaning.
