My nightly Macrium Reflect images are my fail-safe. In all the time I've used Macrium Reflect, I have yet to actually restore an image. Although I have, on occasion, mounted an image in Microsoft File Explorer and copied a file or two that I needed.
I do something very similar, except at the opposite side of the day. My system automatically powers on in the morning, then the daily backup is scheduled for 5 minutes after power on. This way, when I start my day, a backup has already been performed before I can go and mess anything up
.
I actually do 2 separate backups with Reflect. First it performs an image backup of the C: drive (incremental daily, full image on Sundays). After the image backup, all my critical data is backed up as a file and folder backup rather than a disk image backup. Same thing with it: Incremental daily, full backup on Sundays.
Then, as an extra layer of protection, I sync all my important data to multiple other systems using FreeFileSync. On those destinations, all changed files are saved as previous versions in an archive folder and maintained for one year. One of those destinations is an all-purpose 1 TB USB Flash Drive that is my last resort recovery disk. From that UFD I can boot and install multiple different versions of Windows, boot my Macrium Reflect recovery disk, and more.
About once a month I do bit-by-bit comparisons of my original data with replicated data.
I've had some close calls over the years, so I'm maybe excessively aggressive in protecting my data
