REMOTE DISASTER DATA RECOVERY SYSTEM AND METHOD
First Claim
1. A disaster recovery computer system comprising:
- a primary volume located at a first location, comprising a primary data set to be archived for disaster recovery;
at least one computer having programming associated therewith, the at least one computer communicatively connected to the primary volume;
at least one local archival storage unit communicatively connected to the computer and located at the first location, wherein(a) the computer programming when executed provides data transfer and control capability to create at the local archival storage unit a disaster recovery volume of the primary volume on at least one storage medium, and(b) the computer programming stores in the at least one storage medium an identification of the data source to identify that the disaster recovery volume on the at least one storage medium corresponds with the primary volume; and
at least one remote archival storage unit at a second location for receiving the disaster recovery volume when it is physically relocated away from the first location of the primary volume to make a remote disaster recovery volume available for data protection or recovery of the primary volume, wherein the identification of the data source stored in the at least one storage medium at the local archival storage unit is maintained with the disaster recovery volume upon relocation to the at least one remote archival storage unit to enable disaster recovery of the primary volume at the at least one remote archival storage unit.

Abstract
The present invention provides computer systems, methods, and software products enabling the creation and maintenance of disaster recovery volumes having a reduced impact with regard to network traffic over a communications network. A disaster recovery volume is generally created at a local archival storage unit including therein at least one storage medium constituting the disaster recovery volume. The medium constituting the disaster recovery volume is associated with the primary volume thereby allowing the storage medium constituting the disaster recovery volume to be relocated to a remote archival storage unit at a remote location without compromising the association between the primary volume and the disaster recovery volume. Incremental changes to the primary volume may then be communicated and incorporated in to the disaster recovery relocated to the remote location.

14. A disaster recovery computer system comprising at least one client computer and at least one server computer each communicatively interconnected to at least one local archival storage unit and at least one remote archival storage unit, the client and server computers having programming associated therewith that when executed provides data transfer and control capability to create a disaster recovery volume of a primary volume on at least one storage medium, which at least one storage medium constitutes the disaster recovery volume, at the local archival storage unit, wherein the computer programming identifies the primary volume as corresponding to the disaster recovery volume by including a tag in the at least one storage medium that maintains an association between the at least one storage medium and the primary volume to provide for disaster recovery of the primary volume after the at least one storage medium is relocated to a remote location, the computer programming further identifies and packages incremental changes to the primary volume and communicates the incremental changes over a communications network to a particular disaster recovery volume relocated to the remote archival storage unit at a location remote from the local archival storage unit.

15. A computer readable medium storing program code which when executed on a computer, causes the computer to perform a method for creating a disaster recovery volume of a primary volume associated with a first computer, the method comprising:
-
packaging a primary data set associated with the primary volume; communicating the packaged primary data set associated with the primary volume to a local archival storage unit including therein at least one storage medium; copying the packaged primary data set to the at least one storage medium, the at least one storage medium constituting the disaster recovery volume; and associating the at least one storage medium constituting the disaster recovery volume with the primary volume by storing in the at least one storage medium an identification of the data source that is maintained after the disaster recovery volume is relocated to a remote archival storage unit at a remote location to provide disaster recovery of the primary volume at a remote disaster recovery volume. - View Dependent Claims (16, 17, 18, 19, 20)
