You can manually export your data from a specific database at any time. You can also schedule backups of your databases to make sure you always have valid backups. The backup process can be scheduled for every 1, 4, 12 or 24 hours from the time that you save the backup configuration.
You can schedule backups to these locations:
- FTP server
- SFTP server
- Amazon S3
- Local mount point
- OpenStack Swift (Object Storage)
Other cloud storage options, including Azure Geo-Redundant Storage and Google Cloud Storage, are planned for a future release.
The backup process creates compressed (.gz) RDB files that you can import into a database. If you backup a database configured for database clustering, RS copies a backup file for each shard to the specified backup location.
- Make sure that you have enough space available in your storage location. If there is not enough space in the backup location, the backup fails.
- The backup configuration only applies to the node it is configured on.
Scheduling Periodic Backups
To schedule periodic backups for a database:
- In databases, click on the database that you want to configure backups for.
- In configuration, select Periodic backup.
- Select an interval for the backups to run either every 1, 4, 12 or 24 hours.
- Select one of the available storage types.
- Enter the details for the selected storage type.
- To save the database configuration, click Update.
Before you specify to backup to an FTP server, make sure that:
- The RS cluster has network connectivity to the FTP server.
- The user that you specify in the FTP server location has read and write priviledges.
To backup to an FTP server, enter the FTP server location in the format:
Before you specify to backup to an SFTP server, make sure that:
- The RS cluster has network connectivity to the SFTP server.
- The user that you specify in the SFTP server location has read and write priviledges.
- The RS server and SFTP server have the correct TLS certificates. You can select either:
- Use the cluster auto generated key - Go to settings and copy the Cluster SSH Public Key to the SFTP server.
- Use a custom key - Generate a TLS key pair for the SFTP server, copy the private key to the SSH Private Key box, and copy the public key to the SFTP server.
To backup to an SFTP server, enter the SFTP server location in the format:
Before you specify to backup to Amazon S3, make sure that you have:
- Path in the format:
- Access key ID
- Secret access key
Local mount point
Before you specify to backup to a local mount point, make sure that:
- The node has network connectivity to the destination server of the mount point.
redislabs:redislabsuser has read and write priviledges on the local mount point and on the destination server.
To backup to a local mount point for a node:
On each node in the cluster, create the mount point:
- Connect to the terminal of the RS server that the node is running on.
Mount the remote storage to a local mount point.
sudo mount -t nfs 192.168.10.204:/DataVolume/Public /mnt/Public
In the path for the backup location, enter the mount point.
Before you specify to backup to OpenStack Swift, make sure that you have:
- Storage URL in the format:
- Prefix (Optional)
