I'm having a concern that I have no backups for 12TB of files since 2008. So I'm trying to back up everything on Backblaze and Google drive. I'm going to pay for Backblaze and Google drive offers unlimited space thanks to my previous school. I will be going to buy a few HDD in real life as an option. But I wonder if it's ok to back up all files on Google drive or not? Backblaze and Google drive wont be the prime backups and I dont need to access them again unless I need to. I just wanna backup all filled HDD for long term storage.
