I worked in backup software for 22 years until a few years ago. My suggestion is to make a backup and store it for long term on an external drive. The to the cloud full followed incremental backup daily so you can go back to any point along the way at any time. Currently I use Acronis and it works well. I backup to their cloud to avoid having my local backups also encrypted preventing restoring in the event of failure or malware. Good backup strategy would not overwrite old backups until you must and backup regularly, so you don't lose any more data than you can afford to lose. Remember recovery time as well.
