Snapshot capabilities for Redis

Introduction: Redis is a memory-based database and also provides a number of persistent scenarios that allow users to write in-memory data to the local file system for the next reboot or after the machine continues to be used. This article describes how to set up these features based on Redis.

Settings for snapshots

A. Setting up the redis.conf configuration file

The frequency of Redis snapshot writes

Save 900 1

Save 300 10

Save 60 10000

Snapshot file name settings

Dbfilename Dump.rdb

Snapshot Catalog Color Rendering

Dir/opt/redis

Disable aof, because the AOF priority is higher than the snapshot, so after it is set to OFF, you can use snapshot

AppendOnly No

B. start Redis Server

C. run redis-cli, manipulate some data, and save

D. View dump Data file

E. After restarting Redis-server, you can still read the previous data

From the above process, we can already see the entire snapshot of the use of the process.
