Hi, I'm new to Acronis. I'm running 2010 on Win 7 prof, I have scheduled incremental backups of my OS and my docs that reside on a different HDD. The initial backup worked OK but now at each scheduled backup I get the message scheduler failed to run task choice 0, with GUID "}because of Error 87. I have checked the backup tasks and they appear to have completed OK. Can anyone help please. The log file is attached.
