How Do I Export DCS Redis Instance Data?

  • Instance data of DCS instances other than single-node ones can be exported on the console:
    1. Go to the Cache Manager page on the DCS console.
    2. Click the name of the desired instance. The instance details page is displayed.
    3. Choose Backups & Restorations.
    4. If No records found is displayed, perform a backup and click Download.
  • Single-node instances do not support the backup function. You can use command SYNC on redis-cli to export data to RDB files.
    • If the instance allows the SYNC command, run the following command to export the instance data:

      redis-cli -h {source_redis_address} -p 6379 [-a password] --rdb {output.rdb}

    • If the instance does not allow the SYNC command (such as a Redis 4.0/5.0/6.0 single-node instance), migrate the instance data to a master/standby instance and export the data by using the backup and restoration functions on the console.
