I'd like to bracket the matter of whether to use the Secure Zone and focus on how to use it. A recent experience tends to persuade me of its value. I had three backup archives on two partitions and on the Secure Zone, and the two others were corrupted. Limited sample size and all that, but it leads me to at least give Acronis the benefit of the doubt as to its wisdow. Failed backups happen too often. Perhaps it is often the result of corruption by other software. From one angle, it is almost self-evident, but that's not what I want to discuss. Let's say we go with the Secure Zone as the preferred main backup location. What covers the hole in main protection when the Secure Zone becomes full and must discard the contents of an archive? When the whole archive gets trashed because there's no room to expand, you are entirely dependent on auxilliary backups during the interval between the trashing and its replacement. What does Acronis recommend as a best practice to avoid or at least counter this vulnerability? Does Acronis recognize this problem as a defect in the current Secure Zone implementation?
