I've just upgraded to TI11 -- but each time I have used it, I get an error msg in mid-backup, either a) telling me backup drive is full (it isn't) or there has been an error due to bad quality media (the HD is fine, no problems). Uninstalled TI11 and returned to TI10, and all problems disappeared, backups have continued as normal since. OK I know these probs can arise, especially with new versions. But can't they get even the basic stuff right? Did Acronis do any serious testing before release? -- or are they as usual relying on users to do the testing for them? Whatever, it's a yawn. I guess we'll just have to wait until the next upgrade for the gold standard working version.
