In this release, we have started to add integrations with cloud services and initially plan to add support for the major public cloud providers – Amazon Web Services, Google Cloud, and Azure.

We are reintroducing backup to the cloud where you can now manually upload or schedule backups to be stored on AWS S3 and Google Cloud Storage. You can then download and restore backups from the cloud in case of local backup storage disasters or if you need to reduce local disk space usage for your backups.

For MySQL-based clusters we have added support for MariaDB 10.2 and you can now choose to initially stage a slave from an existing backup instead of staging from a master. Individual databases (mysqldump only) can be backed up with separate dumps/files, and you can trigger verification/restoring of a backup to happen after N hours after a scheduled backup has completed.

PostgreSQL has an additional backup method pg_basebackup that can be used for online binary backups. Backups taken with pg_basebackup can be used later for point-in-time recovery and as the starting point for a log shipping or streaming replication standby servers. We have also added support for synchronous replication failover and deploying HAProxy with Keepalived (for load balancing HA) to be used with PostgreSQL clusters.

Load balancers (HAProxy) can be deployed by explicitly selecting the public/management IP for connecting and provisioning the software. Especially useful for cloud environments if you are provisioning/managing over a public network.

We also have some additional improvements for ProxySQL. You can add or modify schedulers and also mass import existing database users into your ProxySQL instances to quickly set up access.
