Abstract
A method, system, and computer program product that enable integrated scheduling and management of frozen images for backup and recovery purposes. Frozen images are created, cataloged, and managed in accordance with a backup policy including a schedule for generating frozen images. Minimal data are saved to allow fast synchronization of the persistent frozen images with production data, and frozen images are cataloged in a catalog that may include entries for other types of backups to provide a single source of information for all backups of production data.
Claims24
A method comprising:
- adding an entry for a frozen image of data in a catalog for tracking a plurality of versions of the data when the frozen image is generated, wherein the plurality of versions of the data comprises:
- a first version of the data corresponding to the frozen image;
- and
- a second version of the data stored on a sequential access storage device;
- and
- the catalog comprises:
- a first entry corresponding to the frozen image;
- and
- a second entry corresponding to the second version.
A method comprising:
- adding an entry for a frozen image of data in a catalog for tracking a plurality of versions of the data when the frozen image is generated;
- and
- logically rotating a plurality of storage areas to store a plurality of frozen images, wherein a respective frozen image is determined in accordance with a rotation schedule for the storage areas.
A computer-readable medium comprising:
- adding instructions configured to add an entry for a frozen image of data in a catalog for tracking a plurality of versions of the data when the frozen image is generated, wherein the plurality of versions of the data comprises:
- a first version of the data corresponding to the frozen image;
- and
- a second version of the data stored on a sequential access storage device;
- and
- the catalog comprises:
- a first entry corresponding to the frozen image;
- and
- a second entry corresponding to the second version.
A computer-readable medium comprising:
- adding instructions configured to add an entry for a frozen image of data in a catalog for tracking a plurality of versions of the data when the frozen image is generated;
- and
- rotating instructions configured to logically rotate a plurality of storage areas to store a plurality of frozen images, wherein
- a respective frozen image is determined in accordance with a rotation schedule for the storage areas.
A computer system comprising:
- a processor to execute instructions;
- and
- a memory storing the instructions, wherein the instructions comprise:
- adding instructions configured to add an entry for a frozen image of data in a catalog for tracking a plurality of versions of the data when the frozen image is generated;
- and
- rotating instructions configured to logically rotate a plurality of storage areas to store a plurality of frozen images, wherein
- a respective frozen image is determined in accordance with a rotation schedule for the storage areas.
