I was asking about backup software for Windows the other day and a couple people recommended Cobian Backup. It’s simple to use, but also very configurable. And it’s free.
You can have the software simply copy files or you can have it zip the output (
.7z format). In either case, you don’t need the backup software in order to restore your files.
The software has all the features you’d expect. You can perform full, incremental, or differential backups. You can run backups manually or as scheduled tasks. Etc.
