I have always been pleased with my web host, JaguarPC. They recently implemented a program where they will automatically upgrade your account with additional space to match their current plans. That meant that one day, I noticed I had over 16 GB of free space on my webserver!
So what should I do with all that space? My first thought was to change my photo uploading process so that I upload every picture I take to my webserver. This would mean that I can refer to my entire picture collection regardless of where I am. Donna thought this was a bad idea, and I eventually came around. Not only are there plenty of pictures that show my daughters not fully dressed, but also there are plenty of bad pictures that don't make sense to upload.
So instead I thought of using it as backup file storage. I could create an Applescript process to upload particular files to a secure area on the server. If I run this routinely, I'll have a really easy backup process.
My first attempt at an Automator workflow for this worked! All of a sudden (well, it took 25 minutes for the files to upload), I had backed-up much of Donna's critical files to my webserver. It's pretty crude right now, in that the locations that are backed-up are hard-coded, it does not retain any folder structure, and it just copies everything up each time you run the backup (not just the recently changed files), but I don't know if I'm real concerned about those details for an emergency backup. I'm sure I'll spend some time to tweak the process over the next few weeks.
