transmission
Bit-for-bit (1:1) copy
operation
When is bandwidth
consumed?
Per schedule, usually off-

Throughout the day, may
coincide with user activity
How many backup sites are

Multiple sites, from one site
to many based on setup
Single site, from one site to
another
Is tuning supported? Initiates multiple jobs to
overcome delays
Single job only
You may use Autocopy and Instant DR separately or at the same time. However, if Autocopy and
Instant DR are used simultaneously, it should be noted that they may not be run on the same virtual
tapes. For example, you may run Autocopy on vtapeA in PoolXYZ while also running an Instant DR job
on vtapeB in PoolXYZ. However, you cannot run Autocopy on vtapeA in PoolXYZ and then immediately
run an Instant DR job for PoolXYZ in its entirety. This is because vtapeA will be in use and locked by
Autocopy. In this case, the Instant DR job would fail.
Configuring network settings
You must configure network settings for all VTS locations. To configure the primary (local) system,
you must attach a monitor, keyboard, and mouse to the VTS server. To configure secondary (remote)
systems, you must use a remote-access application to access those systems, or perform the steps at
each site. The IP address, which will differ for each VTS server, must be configured at the primary
and secondary sites. Consult your network administrator to determine the gateway and subnet mask
to use for each system.
In addition, you should be familiar with networking concepts to complete the steps in this section.
Obtain the following information before beginning this procedure:
l Root access to the VTS system; refer to the Configuration Guide for a list of the default
accounts provided on the server
l IP address, subnet mask, and gateway of each VTS server
