Redis provides the functionality to create and restore backups of your database. Let's see how you can do it.
For creating a backup, Redis uses the
BGSAVE commands. The
SAVE command operates synchronously but will block other operations until it has completed. On the other hand,
BGSAVE performs the backup process in the background. Here is an example:
After running this command, a dump file named
dump.rdb will be created in your Redis directory.
Restoring a backup in Redis is quite simple as well. It involves just moving your backup file (
dump.rdb) to the proper Redis directory and starting your server. Redis automatically loads the
dump.rdb file on startup. The default directory can be found in your Redis configuration file (redis.conf) under the
Here is a simple example of restoring a backup:
First, stop your Redis server:
Then, move your backup file to the Redis directory:
Finally, start your Redis server again:
Please note, the path
/path/to/redis/dir/ need to be replaced with actual paths in your system.
In conclusion, Redis makes it easy to create backups using the
BGSAVE commands and restoring them by simply moving the backup file to the correct directory and restarting the server. Be sure to always back up your data regularly and verify your backups for security and reliability.
