Section: Data Protection

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

The pktt command controls a simple on-filer packet tracing facility. Packets can be captured into a trace buffer then dumped to a file, or the captured data can be logged to a file. The data is stored in "tcpdump" format, and can be directly viewed with tcpdump, ethereal, and perhaps other viewers. The output can also be converted using the editcap(1) program to a variety of other formats, including Sniffer, NetMon, and snoop.

Two multipath methods are supported:

The multiplexing mode causes snapmirror to use both paths at the same time. If one should fail, it will switch to use the remaining path only and use both again should the failing path be repaired.

Failover mode causes snapmirror to use the first path as the desired path and only use the second path should problems arise with the first path.
