  Insufficient data for a meaningful answer.

  Start with the nodes involved:

AA = database server
BB = backup processor
CC = old backup storage target
DD = new backup storage target

  For each node, describe:

* Make and model of machine
* Physical CPU
* Physical RAM
* HDD (spindle speed, spindle count, disk/controller cache, attachment
type & speed)
* OS, Edition, 32/64 bit, Service Pack

  If the node is virtualized, also provide:

* Virtualization software and version
* Host OS, Edition, 32/64 bit, Service Pack (if not dedicated virtualization OS)
* CPU assigned
* RAM assigned
* Type of virtual storage (virtual disk, pass-through, etc.)

  You provided some of this information for CC and DD only.

  So... to divide this into stages:

P1. Software running on BB connects via network to AA, running DB2
protocols over the wire, and dumps database data to files on local
storage

P2. Software running on BB compresses those files to ZIPs, also on local storage

P3. Software running on BB connects via network to CC or DD, using
SMB, and copies the ZIP files from local storage to storage on the
remote node

  Is this correct?

  Does the DBA know if steps P1 and P2 are still taking the same
amount of time?  If not, the problem might be in P2 or P2 and just
happened to start around the same time as the CC to DD switch was
made.  Sure, this is an unlikely coincidence, but they do happen.

  Also, is the network path from BB to CC, and from BB to DD,
identical -- down to the switch port, wall jack, and cables?
