As part of the normal course of operations, Rego maintains a robust backup and recovery management service. The Rego managed infrastructure is designed in a highly available configuration to ensure service continuity. The infrastructure and plan are routinely tested for risks, threats and availability. The recovery point objective (RPO) < 1 hour. The recovery time objective (RTO) is < 4 hours.
DEFINITIONS:
RPO: Recovery Point Objective – The interval between snapshots, the maximum data that may be lost.
RTO: Recovery Time Objective – The duration to fully restore a database and Clarity services.
PITR: Point-in-Time-Recovery – Frequent archive of database transactions for incremental rollback
Snapshot: A database snapshot is a differential database backup
UTC: Coordinated Universal Time - To ensure that daylight savings and global times are aligned
Business Weekday: Rego maintains a business week as Sunday 08:00 UTC – Friday 22:00 UTC
Maintenance weekends: All operations are locked down during maintenance weekends
STANDARD PRODUCTION BACKUPS:
8-day backup for PROD environments with a 5-minute PITR for those 8 days. Separate twice-daily full backup for PROD is stored for up to 4 weeks. This includes the following details:
An 8-day point in time backup for PROD databases with a 5 minute RPO
An 8-day daily incremental snapshot for the PROD database taken at approximately 01:00-02:00 UTC
An 8-day daily incremental snapshot for the PROD database taken at approximately 07:00-08:00 UTC
An 8-day daily archive for PROD filestores
Separate once-per-day full backups are captured and stored for up to 4 weeks
All backups are encrypted and stored in multiple AWS datacenters within a region
A full backup is always taken prior to a Clarity application upgrade by default
STANDARD NON-PRODUCTION BACKUPS:
7-day daily snapshot backup for NON-PROD environments for disaster recovery purposes only. This includes the following details:
A 7-day daily incremental snapshot for the NON-PROD databases taken at approximately 01:00-02:00 UTC
A 7-day daily archive for NON-PROD filestores
