There are a number of good systems for synchronising directories, if you are the only person who works on them. rsync, unison and sitecopy can all be set up to run automatically and keep all your systems up to date.

Systems like WebDAV and CVS are great if there are multiple people working on the same code, and you have to make sure they don't clobber each others changes. However they both require a bit more work to use, since you have to go to the effort of locking the file and downloading it before you work on it.

All my scripts get archived every day by an automatic script, and backuped up to another server once a week.
