Rats!!! I sorry you lost your TM backup, but I'd suggest the title should say, "Don't Trust Any Single Type of Backup Method". I'd also heard that networked drives were not as safe, thanks for your personal verification! While I use CCC, I've never had to use its backup to boot into it. I noticed that the author says he could boot up any of his TM backups. I assume that's just a typo. I don't think TM backups are bootable. Even if they are uncorrupted! That's why I also use CCC. Another reason is that I've had at least two TM failures which resulted in a complete loss of all data. I just don't trust magnetic material!
Only consolation is that you may actually have all those TM files in your CCC backup. However, they may be a bit harder to locate.
