While this version is more relevant to 'tiger' it functions like it always has for at least 10.3.9.
I use iBackup every week to backup my PowerBook to my external. While this new version certainly looks better, more relevantly it's still a solid, easy-to-use backup for what I consider "mundane/pertinent" data.
It is unforunate that someone has realized an issue with it on a networked system. I hope they and/or the developer resolve the issue. By the look of the total downloads of iBackup, it is popular and rightfully so. Five Stars.
