Abstract
An apparatus and method for faster recovery of validated continuous data protection time images. In one embodiment of the method, an image validation process is initiated. In response, a first write transaction is generated for writing first new data to a first image of a data object that existed at prior time T1. The first new data is written to a first storage. Thereafter data contents of the first storage are copied to a first memory object. Finally, the first memory object is linked with the first image.
Claims20
A method comprising:
- initiating an image validation process;
- in response to initiating the image validation process, generating a first write transaction for writing first new data to a first image I1 of a data object that existed at prior time T1;
- writing the first new data to a first storage;
- creating a first entry in a first memory object;
- and
- linking the first entry with I1.
A computer readable medium comprising computer executable instructions, which, when executed, result in a method, the method comprising:
- in response to initiating an image validation process, generating a first write transaction for writing first new data to a first image I1 of a data object that existed at prior time T1;
- writing the first new data to a first storage;
- creating a first entry in a first memory object;
- and
- linking the first entry with I1.
An apparatus comprising:
- a computer system, the computer system comprising a memory for storing instructions executable by the computer system, wherein the computer system implements a method if the computer system executes the instructions, the method comprising:
- in response to initiating an image validation process, generating a first write transaction for writing first new data to a first image I1 of a data object that existed at prior time T1;
- writing the first new data to a first storage;
- creating a first entry in a first memory object;
- and
- linking the first entry with I1.
