Point-in-time backup utilizing multiple copy technologies
First Claim
1. A computer-implemented method for performing a point-in-time backup of source data stored in one or more storage devices that support one or more backup and copy technologies, the method comprising the steps of:
- (a) suspending updates to the source data;
(b) identifying one or more extents for the source data and a type of data storage device storing the identified extents;
(c) determining at least two copy technologies available for the identified type of storage device to create a point-in-time copy of the extents for the source data;
(d) selecting one of the determined copy technologies; and
(e) making a point-in-time copy of the identified extents using the selected copy technology.

Abstract
A method, apparatus, and article of manufacture for performing a point-in-time backup using multiple copy technologies includes steps of suspending execution of updates to the source data; determining what point-in-time backup technology is supported by the device by determining the device and extents of the source data; processing each of the extents as determined by the backup technology supported and copying the source data in point-in-time; and backing up copied entire source data to a target media. If the backup process fails, the method, apparatus, and article of manufacture provides a restart function.

13. A computer-implemented system for performing a point-in-time backup of source data stored in one or more storage devices that support one or more backup and copy technologies, comprising:
-
(a) a computer having one or more data storage devices connected thereto; (b) one or more computer programs, performed by the computer, comprising; (i) means for suspending updates to the source data; (ii) means for identifying one or more extents for the source data and a type of data storage device storing the identified extents; (iii) means for determining at least two copy technologies available for the identified type of storage device to create a point-in-time copy of the extents for the source data; (iv) means for selecting one of the determined copy technologies; and (v) means for making a point-in-time copy of the identified extents using the selected copy technology. - View Dependent Claims (14, 15, 16, 17, 18)
