Don't hesitate to get Carbon Copy Cloner if you are in need of a backup solution for your Mac - you won't regret the decision. Ultimately, he was able to identify the problem as being due to runaway crash reports from a faulty piece of software, and walk me through the steps necessary to get rid of the issue and assure a clean backup, and to give me some advice on next steps to deal with the disc replacement process. Over the course of three days, I exchanged a number of emails with Mike Bombich, who got back to me with analysis of my CCC log files within a few hours each time. But the thing that really makes me sing Bombich's praises is the quality of its customer support. The documentation is a model of clarity, and serves as an educational repository and resource on the philosophy of backup strategies that greatly enhances one's understanding of the product and its use. See your product manual for which Toolkit activities are supported by your drive. It does the job of providing a robust backup solution for your Mac in a clean, elegant manner. Get the most out of your storage solution with easy-to-use tools such as Backup, Mirror, Sync Plus, Seagate Secure, and RGB and Status LED Management.
