Backups are essential when you’re dealing with important data. Hard disks fail, file systems break. For DEVONthink Pro, one option is to export all items to a folder in your file system and move it to a safe place. For example your .Mac iDisk or your Amazon S3 JungleDisk. You can do this manually or by using the Backup Archive script supplied with DEVONthink Pro. Or, you could use the following two scripts that make it more-or-less a one click process.
To use them, download the above scripts and unpack them. Then, copy the .scptd files into ~/Library/Application Support/DEVONthink Pro. If DEVONthink Pro was open, choose Scripts > Update Scripts Menu. Both scripts should now appear in DEVONthink Pro’s own script menu (left of the Help menu, with a stylized AppleScript ‘S’ symbol).
As always, comments are highly appreciated!
