You should be aware of basic SnapMirror limitations before creating a data protection relationship.

  • A destination volume can have only one source volume.

    Note A source volume can have multiple destination volumes. The destination volume can be the source volume for any type of SnapMirror replication relationship.

  • Depending on the array model, you can fan out a maximum of eight or sixteen destination volumes from a single source volume. See the Hardware Universe to learn details for your specific configuration.

  • You cannot restore files to the destination of a SnapMirror DR relationship.

  • Source or destination SnapVault volumes cannot be 32-bit.

  • The source volume for a SnapVault relationship should not be a FlexClone volume.

    Note The relationship will work, but the efficiency offered by FlexClone volumes will not be preserved.
