Redis Data Backup and recovery

The Redis SAVE command is used to create a backup of the current database.

Grammar

The basic syntax for the Redis Save command is as follows:

1. Redis 127.0. 0.1:6379> SAVE

Instance

1. Redis 127.0. 0.1:6379> SAVE
2. Ok

This command will create the Dump.rdb file in the Redis installation directory.

Recovering data

If you need to recover data, simply move the backup file (DUMP.RDB) to the Redis installation directory and start the service. To obtain the Redis directory, you can use the CONFIG command as follows:

2. Redis 127.0. 0.1:6379> CONFIG GET dir
3. 1) "dir"
4. 2) "/usr/local/redis/bin"

The above command CONFIG GET dir output Redis installation directory is/usr/local/redis/bin.

Bgsave

You can also create a Redis backup file using the command BGSAVE, which executes in the background.

Instance

1. 127.0. 0.1:6379> BGSAVE
3. Background Saving started
