I have long liked Macrium, but I’m becoming tired of it. On the other hand, the free version is good, but lacks some important features (Macrium also makes it very difficult to find it.) I have stopped updating unfortunately, because the program has become bloody expensive, and the price can’t be justified for personal use.

The prompt is postponed if a backup process is running at the time. Existing users of the backup software will get a prompt on the first start after upgrading the software to the latest version. Reliability problems of the Windows Task Scheduler are the main reason for integrating a native solution. WTS has been the only method for scheduling Macrium Reflect backups for many years, but unfortunately it's been plagued with reliability problems surrounding Daylight Savings Time (DST) changes and no longer provides the quality of operation required by Macrium Reflect. We've integrated our own scheduler into Macrium Service to replace the default Windows Task Scheduler (WTS).

Macrium highlights the main reason for making the change in the 'new in Macrium Reflect 7.3' support article on the company website: The new Macrium Reflect 7.3 update introduces support for a native task scheduler that users of the software may use instead. If you are using the backup software Macrium Reflect, you may know that it relied solely on the Windows Task Scheduler for backup tasks.
