Error: Failed to open Data Stream

Thread needs solution

I have just received an error message saying "Failed to open Data Stream", so I followed the links to Windows Process Explore, which I downloaded and ran. WPE told me that Windows Explorer was running at the time of the error. As Explorer is always running when Windows is running, I don't know how to interpret this message. It is also interesting that running a Validate on this 'failed' backup says that "The backup is valid" - does this mean that this particular error message can be safely ignored?

The best thing to do is to:
- move your existing TIB files of the failing backup task(s) to another directory on the same disk for safekeeping,
- delete your failing backup task(s) from within ATI (ATI will complain it couldn't delete the files you moved, insist),
- reset your failed task(s)

Failed to open Data Stream is a way too common a problem. This should not be a problem with this product and I cannot for my life figure out why
you Technicians cannot fix it other that to tell me to recreate the back up - which I have done four of five times.

I am beginning to conclude this is a bad product. I have purchased 5 or 6 versions of this and each time they get more and more bothersome!

I just started receiving the "Failed to open data Stream". As stated above from "freded", I have also removed the backup, deleted it a number of times and still get the message. I am on build 6525 of True Image 2015 and am running Windows 8.1 64 bit. I have been successfully running backups for months with absolutely no issue. This just started about a week ago and the KB articles don't tell me what to do in Windows 8.1. Any help would be appreciated.

Same problem here. I purchased ATI 2016 40 days ago and now cannot contact customer non-support. I have used this product since True Image 2011 and I will not spend another cent on this software. This is a common problem; why is there not a fix for it except the one that says: delete the backup and start over.
