Since Aura is a managed service, we manage the instance, the underlying services, and backups.
 
Cluster setup:

• As all AuraDB Virtual Dedicated Cloud instances are 3-member clusters, in the event of a single node failure, the cluster will try to recover automatically using one of the other running nodes.
• If this fails, we will intervene and attempt a manual recovery of the failed nodes using the available nodes.
• Since AuraDS instances are single-node deployments, we can only restart the failed member or restore from available backups.

Restoring from Backups: 

• AuraDB Virtual Dedicated Cloud instances are backed up multiple times every day, and the snapshots are retained for 14 days, and manually backed up snapshots for 90 days - AuraDB backup and snapshots retention
• By default, Virtual Dedicated Cloud AuraDB instances are backed up once an hour.
• AuraDS Virtual Dedicated Cloud instances are backed up once a day, and the snapshots are retained for 14 Days and can be manually backed up and retained for 180 days.
• For larger instances, this frequency might be reduced to once every 2 or 4 hours. The customer will be notified about any such changes in backup frequency. 
• We can use these backups to recover your instance if we are unable to restore it completely from available cluster members.

Cross-Region replication:

• Aura doesn't support native cross-region replication, but you can implement it using Aura CDC + Kafka to stream changes from one AuraDB instance to another. Set up a Kafka consumer to apply CDC events to the target instance via the Neo4j driver. Initial data sync must be done manually through a Restore from Backup

 

Time for recovery:

• We provide 24/7 support for Production environments for our Virtual Dedicated Cloud customers and will act upon Sev-1 incidents as soon as we receive them.
• The recovery time, however, depends entirely on the instance size and the complexity of the issue.

Recovery options for the customer:

• In the event of an unexpected data delete/wipe performed by the customer, they can recover the Aura instance to a previous state using one of the available snapshots for the instance.
• Customers can view and download these snapshots from the Aura Console.
• They also have the ability to restore the snapshots to the same Aura instance or a new one.
