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.

SnapVault replicates at the file level not the block level.

Deduplication is always a post-processed activity for Data OnTap, while compression is an inline process.

The deduplication schedule depends on the SnapVault update schedule on the destination system.

A new Snapshot copy replaces the archival Snapshot copy after deduplication finishes running on the destination system. (The name of this new Snapshot copy is the same as that of the archival copy, but the Snapshot copy uses a new timestamp, which is the creation time.)

The SnapVault update recognizes the deduplicated blocks as changed blocks. Thus, when deduplication is run on an existing SnapVault source for the first time, all saved space is transferred to the destination system.

All the network ports should be assigned correct port roles, and all the network ports should be in the same subnet.

OSSV hosts listen for communications from NDMP manager applications on port 10000 by default.

Open Systems Snap Vault runs on servers, so the objects that can be selected for backup will be host-based.

Qtrees are objects on the storage system.
