Abstract
Embodiments of the present disclosure relate to creating and maintaining a separate compliance store within a domain. Files that are committed within the domain are linked to the compliance store using canonical links. Canonical links are guaranteed to be non-erasable and non-rewritable for the duration of their retention period. When using a source cluster of nodes as a primary production cluster and a target cluster of nodes as a backup cluster, file data and canonical links can be synced from the source cluster to the target cluster to maintain compliance with data retention rules. Non-canonical links can be modified as necessary to ensure snapshot consistency when failover or failback occurs between a source cluster of nodes and a target cluster of nodes.
