Sync redis with file system in case of redis failure or data loss

[Clivern]

Redis is sweet in storing and accessing ephemeral data whose loss can be tolerated so we need a different source and file system is the best option.

is probably what you want to recommend - it syncs to disk or s3

"KeyDB is a high performance fork of Redis with a focus on multithreading, memory efficiency, and high throughput. In addition to multithreading, KeyDB also has features only available in Redis Enterprise such as Active Replication, FLASH storage support, and some not available at all such as direct backup to AWS S3."
