In a few different posts, I have sung the praises of Journler the program where I spend most of my creative time on the mac these days. And, you may remember that I contributed some icons to Journeyer as a sort of donation in kind. Well, I just dusted off my bash scripting skills and wrote a simple backup solution for Journler.
Using rsync (which is part of MacOSX), Journler Remote backup (JRB) can make incremental backups of your Journler data to any computer where you have a username and password. Though it should work on WebDav servers (iDisk, box.net, etc.), I have not had a chance to try that out yet. If you use this script, let me know what you think.
