Disaster Recovery

All Hydra plans are monitored continuously by our infrastructure and will automatically recover in the case of hardware failure. All Hydra databases have the option of high availability which allow seamless instant recovery should there be a failure. Plans without HA will typically experience about 5 minutes of downtime while replacement infrastructure is provisioned.

In addition, daily backups and WAL (write-ahead logs) are continuously backed up to an encrypted Hydra Lake bucket for 7 days, providing 11 9s (99.999999999%) durability. Should there be a need to restore your data from backup, we can restore your data to any point in the last 7 days. Should you need this service, please open a support ticket.

Point-in-time Recovery

Point-in-time recovery (PITR) is a method of restoring a database to a specific point in time. This can be useful in situations where data has been accidentally deleted or corrupted, or if you need to undo a series of changes that were made to the database.

With Hydra, PITR is achieved through the use of continuous archiving and WAL (write-ahead logging). Continuous archiving involves constantly copying transaction log files (WAL files) to a remote location as they are generated. This allows us to restore the database to any point in time by replaying the WAL files up to the desired point.

To restore your database to a point-in-time create a support ticket from the Hydra dashboard that includes the following:

• Database name
• Database plan size
• Timestamp (date, hour, and timezone) you would like to restore to

Note that recovery takes approximately 1 hour per 100 GB of data.
