To restore a Redis database backup, perform the following steps.

Step 1

Create a Redis backup using SimpleBackups.

Step 2a

Go to your backup page, then select the "Logs" tab. Afterwards, click the little "( i )" on the right next to the copy you want to download.

Download Your Backup

Step 2b

Under the backup restore section on the modal that just popped up, click on "Click to generate a signed download link" then copy the resulting link

Step 3

On your server, run the following command, and use the signed download link you obtained in the previous step (ensure you enclose it in double quotes as shown):

wget "PasteTheSignedDownloadLinkHereBetweenTheQuotes" -O - | gunzip -dc > "redis-backup.rdb"

Step 4

Check if AOF setting is enabled in Redis before you restore your backup:

redis-cli CONFIG GET appendonly

Sample output of the command:

1) "appendonly"
2) "yes"

If AOF is not enabled (you see "no" in the command output), you can directly go to Step 5.

Otherwise, you need to disable AOF first:

redis-cli CONFIG SET appendonly no



Step 5

5a) Find the current Redis data directory on your system where it stores its database:

redis-cli CONFIG GET dir

Sample output of the command:

1) "dir"
2) "/var/lib/redis"

In our case, the directory is /var/lib/redis - note this directory since we will move our restored backup there later.

5b) Find the current Redis database filename:

redis-cli CONFIG GET dbfilename 

Sample output of the command:

1) "dbfilename"
2) "dump.rdb"

In our case, and usually, the database filename is dump.rdb as shown above - note this filename since we will ensure our restored backup is named like that later.

5c) Shut down Redis (stop the Redis server)

sudo service redis stop

5d) Back up your current Redis database if needed (optional):

cp -rf /var/lib/redis/*.rdb ~/any-redis-backup-directory/

5e) Delete all .aof and .rdb files in the Redis data directory from (Step 5a)

rm /var/lib/redis/*.aof /var/lib/redis/*.rdb

Step 6

Now we will copy the RDB backup file obtained in (Step 3), and restore it into the Redis data directory from (Step 5a) and rename it to the same dbfilename from (Step 5b).

Example based on the values we used in this guide:

sudo cp redis-backup.rdb /var/lib/redis/dump.rdb
sudo chown redis:redis /var/lib/redis/dump.rdb
sudo chmod 660 /var/lib/redis/dump.rdb

Note: If your Redis uses another user on the system that it other than redis, ensure you replace redis:redis by <redis-user>:<redis-user>

Start Redis

sudo service redis start

Quick check on the databases and their sizes

redis-cli INFO keyspace


If you disabled AOF in (Step 4) and you need to enable it again:

redis-cli CONFIG SET appendonly yes
