METHOD AND SYSTEM FOR RESUMING INTERRUPTED DATABASE BACKUP OPERATIONS
In general, the invention relates to a method for performing backing operations. The method includes receiving a user instruction to perform a backup operation on a user asset on a client device, determining that a prior backup operation on the user asset was interrupted, in response to the determination, generating a data file difference subset using a control file and a recovery catalog, wherein the control file is associated with the user asset and the recovery catalog is associated with at least the prior backup operation, and initiating the backup operation using the data file difference subset.
1 . A method for performing backup operations:
receiving a user instruction to perform a backup operation on a user asset on a client device;
determining that a prior backup operation on the user asset was interrupted;
in response to the determination, generating a data file difference subset using a control file and a recovery catalog, wherein the control file is associated with the user asset and the recovery catalog is associated with at least the prior backup operation; and
initiating the backup operation using the data file difference subset.
2 . The method of claim 1 , wherein the control file specifies a plurality of data files in the user asset to be backup during the backup operation.
3 . The method of claim 2 , wherein the recovery catalog specifies a second plurality of data files each of which were backed-up during the prior backup operation, wherein the second plurality of data files is a subset of the plurality of data files.
4 . The method of claim 1 , wherein determining that the prior backup operation on the user asset was interrupted comprises:
identifying a tag file associated with the user asset; and
determining that a parameter in the tag file specifies that the prior backup operation was in-progress.
5 . The method of claim 4 , further comprising:
after the backup operation has been performed:
updating a second parameter in a second tag file to specifies that the backup operation was successful,
wherein performing the backup operation comprises deleting the tag file.
6 . The method of claim 1 , further comprising:
making a second determination that a request to perform a from-incomplete backup been received,
wherein the data file difference subset is generated in response the determination and the second determination.
7 . The method of claim 1 , further comprising:
prior to initiating the backup operation, initiating deletion of incomplete backup asset subcomponents in a last-created data file directory on a backup storage system, wherein copies of data files specified in the data file difference subset are stored in the last-created data file directory during the backup operation.
8 . A system, comprising:
a processor;
a client protection agent, which when executed by the processor performs a method, the method comprising:
receiving a user instruction to perform a backup operation on a user asset on a client device;
determining that a prior backup operation on the user asset was interrupted;
in response to the determination, generating a data file difference subset using a control file and a recovery catalog, wherein the control file is associated with the user asset and the recovery catalog is associated with at least the prior backup operation; and
initiating the backup operation using the data file difference subset.
9 . The system of claim 8 , wherein the control file specifies a plurality of data files in the user asset to be backup during the backup operation.
10 . The system of claim 9 , wherein the recovery catalog specifies a second plurality of data files each of which were backed-up during the prior backup operation, wherein the second plurality of data files is a subset of the plurality of data files.
11 . The system of claim 8 , wherein determining that the prior backup operation on the user asset was interrupted comprises:
identifying a tag file associated with the user asset; and
determining that a parameter in the tag file specifies that the prior backup operation was in-progress.
12 . The system of claim 11 , wherein determining that the prior backup operation on the user asset was interrupted further comprises:
after the backup operation has been performed:
updating a second parameter in a second tag file to specifies that the backup operation was successful,
wherein performing the backup operation comprises deleting the tag file.
13 . The system of claim 8 , wherein the method further comprises:
making a second determination that a request to perform a from-incomplete backup been received,
wherein the data file difference subset is generated in response the determination and the second determination.
14 . The system of claim 8 , wherein the method further comprises:
prior to initiating the backup operation, initiating deletion of incomplete backup asset subcomponents in a last-created data file directory on a backup storage system, wherein copies of data files specified in the data file difference subset are stored in the last-created data file directory during the backup operation.
15 . A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method, the method comprising:
receiving a user instruction to perform a backup operation on a user asset on a client device;
determining that a prior backup operation on the user asset was interrupted;
in response to the determination, generating a data file difference subset using a control file and a recovery catalog, wherein the control file is associated with the user asset and the recovery catalog is associated with at least the prior backup operation; and
initiating the backup operation using the data file difference subset.
16 . The non-transitory computer readable medium of claim 15 , wherein the control file specifies a plurality of data files in the user asset to be backup during the backup operation.
17 . The non-transitory computer readable medium of claim 16 , wherein the recovery catalog specifies a second plurality of data files each of which were backed-up during the prior backup operation, wherein the second plurality of data files is a subset of the plurality of data files.
18 . The non-transitory computer readable medium of claim 15 , wherein determining that the prior backup operation on the user asset was interrupted comprises:
identifying a tag file associated with the user asset; and
determining that a parameter in the tag file specifies that the prior backup operation was in-progress.
19 . The non-transitory computer readable medium of claim 18 , wherein determining that the prior backup operation on the user asset was interrupted further comprises:
after the backup operation has been performed:
updating a second parameter in a second tag file to specifies that the backup operation was successful,
wherein performing the backup operation comprises deleting the tag file.
20 . The non-transitory computer readable medium of claim 15 , wherein the method further comprises:
making a second determination that a request to perform a from-incomplete backup been received,
wherein the data file difference subset is generated in response the determination and the second determination.
