"Operations in progress ..." message prevents PC shutdown ATIH 2014

Hi there,

I am using ATIH 2014 on a Windows 7 notebook. The backups reside on a NAS. The NAS is only used for this backup and automatically powered on between 20:00 and 22:00 and off the other hours.

Following issue: there is a daily incremental  partition backup job  starting on 20:05, typically the PC is on at that time and the NAS as well.

When this time is missed Acronis tries to start the job next time the PC is powered on which often is not successful because the NAS is not available. 

Instead of a simple error message and stopping gracefully the job ATIH will prevent the PC to power down giving the subject message. 

Any ideas how to avoid this? 

I tried all kinds of settings but to no avail. A setting: 'don't retry next time' or 'stop job if destination is not available' would solve the issue but don't seem to be there (or anything like it).

Any advice is very much appreciiated!
