Evernote users, are you vigilant about manually exporting your notes for backup or has it been a while? Evernote Exporter is a simple utility that schedules regular exports of your Evernote data in the app's proprietary .enex file format.
Once the free app is installed, select a directory where you want your note exports saved and choose how often your backups should be made; the app will take care of everything else.
Being that Evernote is a cloud-based app, data losses should be minimal, but if you keep a lot of your life and/or work on Evernote, you'll probably want to have a local backup just in case, and Evernote Exporter automates this.
Evernote Exporter is a free download for Windows XP and greater from the CodePlex open source community.
