Abstract
Official abstract text for this publication.
As disclosed herein, a method for optimizing data synchronization when performing a block-level backup includes receiving a customized merging plan, and creating a padding map that includes missing data information, and sending the padding map to a local backup server to request missing data. The method further includes receiving from the local backup server the missing data, and performing a snapshot consolidation according to the customized merging plan to provide a consolidated snapshot.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, executed by a computer, the method comprising: receiving a customized merging plan; creating a padding map comprising missing data information; sending the padding map to a local backup server to request missing data; receiving from the local backup server, the missing data; performing a snapshot consolidation according to the customized merging plan to provide a consolidated snapshot; and copying a data block from an expired snapshot to the consolidated snapshot, wherein space for a missing data block is reserved with a padding block, and the missing data block is recorded in the padding map. 2. The method of claim 1 , wherein the missing data comprises missing data files. 3. The method of claim 1 , wherein the missing data comprises missing data blocks. 4. The method of claim 1 , further comprising modifying references to expired snapshots in control files corresponding to non-expired snapshots. 5. The method of claim 1 , further comprising deleting expired snapshots. 6. The method of claim 1 , further comprising replacing the padding block with a corresponding data block retrieved from the missing data.
