> My entire life is in Google: GMail, Google Drive, and Photos. I'm happy with it except for the fact that I'm terrified of getting locked out and losing everything.

This has been my fear lately. Especially after Facebook banned my account earlier this year for "account integrity" issues. An account I had since 2011. My appeals failed and my emails to them went unresponded to. I made a post about it here - https://news.ycombinator.com/item?id=43420648

It made me realize I can't just leave personal data with an organization that can just ban me whenever they feel like.

I've thought about backing up everything to my OneDrive so that I have two backups, I mean, what are the odds that I get banned by Microsoft and Google at the same time before I can find another cloud provider?

I don't know, I'll follow this thread for better suggestions.

For Drive and Photos, Relica can do this. Full disclosure: I develop the software.

It uses restic under the hood (so you get deduplication, encryption, immutable snapshots) and rclone for cloud connectivity. Backs up to your NAS or multiple destinations, runs on a schedule, GUI instead of cron jobs and scripts. $5/month for the software, storage is yours.

Gmail is harder. It's not a filesystem so restic/rclone-based tools don't handle it. Your best bet there is probably Google Takeout on a schedule (annoying but works), or something like gmvault if you're comfortable with Python scripts.

The lockout fear is real. One option: backup Google Drive → your NAS → a second cloud provider that isn't Google (Or Relica Cloud for managed redundancy). Relica can chain those so you upload once and it replicates. Check relicabackup.com
