Managed Services Backup : Geo- and zone redundancy for data recovery

Geo-redundancy and zone-redundancy in detail

Geo-Redundant Storage (GRS) and Geo-Zone-Redundant Storage (GZRS) are, for example, two options for different redundancy requirements. GRS replicates data synchronously in a primary region and asynchronously in a secondary region. The availability of resources in different regions plays an important role here. By combining GRS and RA-GRS, data can also be accessed in the secondary region in the event of an emergency. This enables faster failover and a shorter Recovery Time Objective (RTO). To ensure even better availability and protection against data loss, GZRS can be used, which also offers zone redundancy. This protects data against regional (geo-redundant) and data centre (zone-redundant) failures.

There are various aspects to consider regarding backups and recovery: The redundancy options and backup strategies used should be tailored to the organisation’s individual requirements and be in line with data protection regulations, business needs and compliance requirements. This ensures that our data and applications are protected as effectively as possible, even in the event of unexpected incidents.
