Some problem with Optimized Duplication

There are various types of SLP duplication/replications that cannot be suspended.

See extract from page 2 of the doc:

The exact behavior when the window closes will depend on the storage devices involved and the type of data the operation is carried out on. By default the operation will suspend processing of the “active” images at the time the windows closes and resume where it left off the next time the window opens.

However for some storage types, including deduplicating disk storage and NDMP devices, suspending and resuming is not possible. Where these storage types are used the default behavior is to finish processing the active images when the window closes before terminating. However the user has the option to terminate the active processing immediately, in which case any partially processed image data will be discarded. In all cases any unprocessed images in the work list when the window closes will be added to the work list when the window reopens.
