Answer

  • Volume level SnapMirror replicates source volume (data), its snapshots, source volume options, CIFS ACLs
  • Volume level SnapMirror preserves NTFS ACLs, including the SIDs within them. However, SnapMirror does not replicate or recreate the underlying user or group identities associated with those SIDs  
  • Volume level SnapMirror preserves NTFS ACLs, including SIDs, but does not replicate access to the data such as CIFS shares, NFS exports, junction paths or SAN configuration.  The data SVM serves the data, and the data SVM configuration is needed to provide this access.
  • SnapMirror does not replicate or recreate the underlying user or group identities associated with replicated ACLs and SIDs. 
    • To replicate both the volume data as well as all or part of the SVM's configuration, consider replicating at the SVM level with SVM DR
  • Volume level SnapMirror replicates qtrees that exist in a volume, but sub-volume, qtree level SnapMirror is no longer supported
