Ok. Having just returned back to my computer after being away all afternoon, whatever job it had been doing is finished. Total size of “MY Backups” is only 289GB. I’m quite sure it was over 300GB when I left at noon. I do notice in the list of snapshots that it somehow missed doing the hourly snaps between 7:00am and 11:00am. I’m assuming this was the big one that had me concerned. Then the hourly ones commenced again at 2:00pm. The very first backup was made automatically 4 days and 10 hours ago. I assume this is my baseline? Should I also do manual backups? As for size, my C: drive is also 1TB with about 300GB used. I’m hoping to use no more than 60% of the backup drive for AX64.
