This is going to be slightly shameless self-promotion, but here goes.
Do you need a simple way to backup important files on your computer?
Say you want run a backup every night of your music, documents, dropbox, etc, to an external hard drive. And, let's say, automatically delete old backups so you only ever keep 30 days worth.
Well, that's exactly what my latest program, psBackup, can do. It can also download a file from your web server every night too-- I use it with my module Daily Site Backup.
Runs on Windows, Mac, and Linux/Unix. You can try it out with the trial version, and if you want to buy it, it's only $4.99. C'mon, support an independent developer ;)
Give it a try and tell me what you think!
