"Failed to create volume snapshot" on system reserved parition for the past 2 days
I have a system running Windows 10 Pro and the latest build of True Image 2016 as of today. It was backing up the system reserved and C paritions fine until yesterday. Since then it has repeatedly failed with an error "failed to create volume snapshot". I removed the system reserved parition from the backup and the C drive backs up without error. However, it is my understanding that the system reserved partition is important in the event of a full system restore. Interestingly I have installed both Macrium Reflect and Veeam Endpoint backup, and they will both back up without errors. Any help would be GREATLY appreciated!

Michael, the error "failed to create volume snapshot" suggests an issue with Microsoft Volume Shadow Copy Service (VSS) which is strange if Macrium works fine for you on the same partitions, as Macrium also use VSS.
You can check this by using the tip from Acronis engineer Slava in post: https://forum.acronis.com/forum/45832#comment-346558 where Slave wrote:

1) open the folder where your backups settings are saved: C:\ProgramData\Acronis\TrueImageHome\Scripts
2) each file there stores settings for particular backup job. Open files one-by-one in Notepad, or open latest modified file (if you have just modified your task), until you find the one that has backup name on 5th line, e.g. MyBackups
3) click Edit - Replace and replace use_vss="true" with use_vss="false"
4) save changes and close the file
Thanks,
Slava
I would also recommend downloading a copy of the Log File Viewer app and checking the logs for any messages which may give more information about this error.
