I have noticed that my Secure Zone, which is located on an entire 300gb drive (internal), has disappeared completely! The reason I say that is the secure zone no longer shows up as an archive location, either for restores or backups. This is true under Windows, Startup Recovery Manager, and Bootable Media Disk. In addition, the second 'page' of the 'Manage Acronis Secure Zone Wizard' asks which disk to create the secure zone on. When the SZ was active, the second page told how much space was available in the zone and the total size of the zone. You should also know that the disk the SZ was on is still 'seen' by TI, just not as a SZ. Also, one other thing that points to the 'disappearance' of the Zone is the backup logs. Everything worked perfectly up to this past Friday morning. I schedule the backup of my system disk at 3am and the backup of my data disk at 4am every day. The 3am backup worked perfectly according to the log. The 4am backup had a message 'Failed to open Acronis Secure Zone for exclusive access.'. Since that time, every backup has failed with the exact same message. This would indicate to me that whatever happened, happened between 3 and 4am on Friday morning. Something that might or might not be relevant is that the SZ was close to being full for the first time. There were many, many Full and Incremental backups within it for both my system disk and my data disk and I had used it several times for restores to my system disk. The archive went back to about Oct 6th of this year. I suspect that the archive got full, had a problem with that and somehow got corrupted (or something) and 'disappeared', for lack of better terminology. This doesn't make any sense to me without it being a corruption issue or something like corruption, because the way I understand it is that the SZ should have looked for the oldest full backup(s) and deleted it and the associated incrementals until there was room for the new backup. What I want to know before going forward are two things: 1) Is there any chance of recovering the SZ and how might I go about doing it? 2) Has anyone seen this situation and/or know what might have caused it? I have more that I want to ask, but I'll leave it at those two questions for now. Any further information you want to share, I will leave it to you to decide. Thanks! P.S. - FYI, I tried very hard to scour the boards to find anyone with an issue like this before posting and came up empty. Perhaps that is mainly a testament to my ability to search effectively, but I did spend considerable effort prior to posting.
