Abstract
Replication techniques may include creating a first file pool on a first site where storage for the first pool is provisioned from a first storage device group configured as a first consistency group; creating a second file pool on a second site where storage for the second file pool is provisioned from a second storage device group configured as a second consistency group; creating a first file system and its first snapshot in the first file pool of the first site, where creating the first file system and its first snapshot include performing first modifications to the first file pool; applying the first modifications to the first consistency group; and replicating the first modifications on the second file pool. Replicating may include applying the first modifications to the second consistency group to replicate the first file system and its first snapshot on the second site.
