No-Persistence
No-Persistence is a configuration option in Redis where no data is saved to disk. In this mode, Redis only keeps data in memory, and any data not yet persisted is lost during a server restart or crash. This mode is useful in scenarios where data durability is not a priority, and the focus is on maximizing performance.
To configure Redis in No-Persistence mode, you can set the following configuration option in the redis.conf
file:
save “”
Note: This configuration disables automatic snapshotting (RDB) and append-only file (AOF) persistence. No-Persistence mode should be used carefully, as it sacrifices data durability for performance gains.
Complete tutorial on Backup in Redis
A Redis backup is a copy of the Redis dataset that is saved to a separate location, typically on disk, to provide a means of data recovery.
- Redis provides several commands and mechanisms to perform backups, including snapshots and persistence options.
- While Redis is known for its high performance and low latency, it’s important to have a backup strategy in place to ensure data durability and recoverability in case of data loss or system failures.
