Recommended actions while using SnapMirror
While using SnapMirror, you can increase the efficiency of data copying by using one or more of the following recommended actions.
Deduplication with volume SnapMirror
Starting with Data ONTAP 7.3 and onward, the deduplication metadata for a volume is placed outside the volume, at the aggregate level. This can improve the space savings achieved through the use of deduplication.
Destination accessibility when using CIFS with SnapMirror
Before copying a directory on a SnapMirror volume that supports CIFS clients, ensure that the directories are in the Unicode format. This will ensure that the read-only directory copied on the destination is in the Unicode format. This will enable requests through CIFS to access the directory and its files on the destination, and prevent “access denied” errors.
Adjusting the TCP window size for SnapMirror
The TCP window size for SnapMirror might have an impact on SnapMirror perfomance. You might have to modify the default value for the TCP window size to suit your network configuration.
