Abstract:
Any point in time backups for distributed consistency is disclosed. IOs from a consistency group are received by multiple aggregators and stored in corresponding journals. In response to a bookmark, the multiple journals are synthesized to create a do stream or to add the multiple journals to the do stream. A full synchronization operation can be performed simultaneously with replication operations.
