I need a tool that will automatically backup data on a mac. I will probably have two macs some how connected to an external hdd. I would like to backup the files on the Mac to the external drive at a certain time everyday. Then I would also like to setup some sort of online automatic backup system. Something that stores the files offsite. I have looked at Mozy and Amazon S3 w/ JungleDisk. Does anyone have any experience in this that could make some suggestions? Thank you very much.
