iBackup for Mac

-- DropBox gives you 2GB for free, and up to 8GB free if you refer enough friends. 50GB on DropBox costs $10.00 / month. TwirlBox gives you 3GB for free, and 55GB for $8.00 / month. Looks like iBackup in not competitive on price.

You can use a free online backup like Cloud/Box.net/Dropbox for up to 5GB. No monthly charge unless you want more space

(I use iDrive not iBackup, but this comment applies to them both equally, and in fact to any other similar off-site backup scheme). This works exactly as advertised, I've used it for maybe 6 months, entirely hassle-free. But be warned: if you are going to back up many gb. of data, it's going to take a long time, maybe up to a week, and your broadband connection is going to take a serious hit (sure, you can apply the throttle control to cut back on its bandwidth use, but this means your upload takes even longer). Personally, if I were going to start all over with one of these services, I'd put it off until the next time I was about to take a long vacation.

What is the difference between iDrive and iBackup? These two seem to have identical software except for the logo. iDrive is significantly less expensive and offers more space, and seems to be actively updated. The iDrive website says both companies are owned by Pro Softnet Corporation. Does iBackup just continue to exist as a first marketing attempt?

Isn't there already a backup utility called iBackup? http://www.macupdate.com/info.php/id/17007/ibackup
