If this option is on, it disables the visible .snapshot directory that is normally present at client mount points, and turns off access to all other .snapshot directories in the volume. The default setting is off.

Because volume SnapMirror works at the block level, the source and destination must both be FlexVol volumes in the same aggregate type. The source and destination of a volume SnapMirror relationship must either both be FlexVol volumes in 32-bit aggregates or both be FlexVol volumes in 64-bit aggregates.

Therefore you cannot create a volume SnapMirror relationship from a FlexVol volume in a 32-bit aggregate to a FlexVol volume in a 64-bit aggregate or vice versa.

NetApp also recommends that if deduplication is used on the source volume, then it should also be used on the destination volume. However, you are not restricted using deduplication on the source volume only.

The deduplication schedule is not tied to the qtree SnapMirror update. In other words, the deduplication process does not automatically start at the completion of the qtree SnapMirror transfer.

The fingerprint database and the change log files that are used in the deduplication process are located outside of the volume in the aggregate and are therefore not captured in Snapshot copies
