"Failed to open data stream" with Full Backup without Validation

Thread needs solution

Hallo,

I know the problem has been discussed several times in the forum, but all solutions I found did not fix

the issue.

I'm using WIN7 and ATI2016 and I'm getting the mentioned error message.

It seems, the backup is correct( at least the backup size seems to be plausible and I can browse the backup),

nevertheless the backup failed. I started totally  new backup sessions (without validation and to other folder) but it still failed.

Finally I deleted the data base (however, two files could not be deleted) without success.

Used to be it worked fine. However, I'm now using the same drive but  a different drive number. Maybe that's

a hint about the problem.

Can anybody help please ?

 

Thank you

Vielen Dank

RTy, if your drive letter has changed or there have been other changes, i.e. you used a different drive at some point, then I would suggest forcing a rebuild of the database files first (as you appear to have done only a partial delete of these previously), and then use the Clone settings option to duplicate your backup task.

To delete the database files fully, you first need to Stop all Acronis Services and then End all Acronis Programs / Processes - it is necessary to do this in this way as otherwise the Services will relaunch any programs you end!

Once you have stopped / ended everything for Acronis, then either delete or rename the C:\ProgramData\Acronis\TrueImageHome\Database folder.

Now when you relaunch the main ATIH 2016 application, the required Services and Processes will be restarted automatically, and the Database files will be rebuilt.

When you use the Clone settings option for a task, it creates a duplicate task with the same name but prefixed by (1).  Do not run this task yet.  Remove the old task settings then edit the new cloned task to check that you have the correct Source and Destination etc, you can also remove the (1) prefix from the name if you wish, but please use a new backup folder if doing so if you have files created by the old task.  This will avoid problems caused by ATIH trying to create a new backup file with the same name as used by the old files.

Steve,

Thank you very much for your detailed answer.

I did what you proposed, but I still have problems to delete a single file. It is "Archives.db".

I killed all Acronis tasks I found with task manager. Nevertheless this single file can not be

deleted.

Do you have any idea what kind of Acronis task or service still blocks that file ? How can I

find out which task  it is ?

Thank you for your help.

Robert, you must kill all the Acronis Services as well as the Acronis tasks (programs).

Type services.msc at the Run prompt or Search window and open the main Services Console and this will show you all the Services, you can also see these from the Task Manager windows where you should also found a button for Services to launch the same console window.

If the Acronis Services are not stopped, these will relaunch the Acronis programs you have ended and keep locks on the Database files.

Hello Steve,

Thank you very much for your great and patient help.

It works! I found the last running hidden Acronis service.

Now database is new and everything works as expected.

Regards

Robert
