Very large DB3 file??
I have noticed a very large .DB3 file (over 2GB) located in C:\ProgramData\Acronis\BackupAndRecovery\MMSData\DML.
I'm guessing the file is a database of the backup history/activity and as such it may contain obsolete information, hence its size. I've been running weekly full True Image backups for a couple of years (retaining 3x full backups).
Is there any way to reduce the size of this file, e.g. prune the database entries? I did try an Acronis remove_history utility but it made no difference at all.

Hi Steve. Thanks for your response.
I tried to raise a support ticket, filled in the form, but when I press next nothing happens. All the fields are filled correctly. No errors. Screen just sits there and does nothing. Tried different browser (IE rather than Chrome) but same thing happens?
I'm tempted to move the file to another location to see what happens. If ATIH messes up I fiugure I can always move the file back?

UPDATE
I decided to do the following:
1. Ended all Acronis processes (via Windows Task Manager)
2. Stopped all Acronis Services (via Windows Task Manager). This removed 2 of the 3 files in the C:\ProgramData\Acronis\BackupAndRecovery\MMSData\DML folder, leaving just the 2GB file remaining.
3. Moved the 2GB file to a temp folder
4. Restarted all the Acronis Services I had previously stopped.
5. The 3 files returned but this time the .DB3 file was just 12KB in size (Has since grown to 240KB)
6. Started Acronis True Image 2016 and everything is working fine. All my backups are still there. I can search through backups and restore files.
So everything seems fine. Will another post update if I have any problems.

Jonathan, that sounds like a very sensible approach and the results look very promising, thanks for feeding back on your actions and the results.
