The case: looking for Windows backup and sync software

Best backup software for Windows

I need to install backup software on a Windows 10 laptop and on a Windows 7 laptop. The software needs to: 1. Backup to a USB external HDD. 2. Automatically backup on a set schedule, once a week. 3. Delete old backups when space runs out on the HDD. Which software is recommended there?

File sync software suggestions?

Hello, I need a free program that checks folder A (and all subfolders) and copies changes across to folder B (and subfolders). It should be reliable (i.e not crash in the middle of a sync job), do the job accurately and have a relatively simple interface.
I have been using FreeFileSync for a while now which does this well but with the amount of adware being bundled of late. I am looking for an alternative. Any suggestions?
