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.
