Enabling Instant DR and AutoCopy
Instant DR is an advanced software module (VT5907 or VT5907-A) that enables you to create
and maintain identical copies of backup data on Virtual TapeServer (VTS) disk storage at one
or more locations. In the event of a disaster, remote recovery operations can begin
immediately using the backup data copy on a remote VTS site.
VTS copies data to remote sites over a wide area network (WAN) TCP/IP connection. Virtual
tapes on the originating VTS server are compressed and transmitted in packets to the remote
VTS server.
If Instant DR is licensed, you can create new Instant DR backup schemes as well as launch
and monitor the remote synchronization processes that are in place.
AutoCopy is also an optional VTS software module, and it enables VTS to automatically copy
a virtual tape from one VTS system to another when a virtual tape has been mounted,
modified, and then dismounted by the NonStop host.
To configure Instant DR and AutoCopy, you must configure network settings for all VTS
locations. Adhere to the following requirements and guidelines when configuring these
software modules:
