How is the strategy for backups and redundancy in a setup like this?

I didn't talk about it in the article, but my strategy is:

1. Local time machine backup (for disk failure recovery)

2. All the Docker container mount in a particular directory, and I periodically sync that directory to an S3 bucket

3. Planning to have Backblaze for more disaster recovery

All of these would have downtime in the event of an issue, but that's ok with me.
