Smart coalescing in data management systems

A data management and storage (DMS) system, comprising:

• a processor;
• and
• one or more memories that include instructions that, when executed by the processor, cause the DMS system to execute a method of creating a local consolidated patch file from a patch file chain stored in a cloud storage comprising:
• in a first phase, creating a logical patch file image of data blocks in one or more cloud patch files stored in the cloud storage;
• in a second phase, downloading at least some of the data blocks from the one or more cloud patch files identified by the logical patch file image, the second phase comprising a coalescing operation to construct a set of coalesced reads of the downloaded data blocks;
• creating the local consolidated patch file using the downloaded data blocks;
• and
• storing the local consolidated patch file in a local storage.

A non-transitory machine-readable medium comprising instructions which, when read by a machine, cause the machine to implement operations in a method of creating a local consolidated patch file from a patch file chain stored in a cloud storage, the operations comprising:

• in a first phase, creating a logical patch file image of data blocks in one or more cloud patch files stored in the cloud storage;
• in a second phase, downloading at least some of the data blocks from the one or more cloud patch files identified by the logical patch file image, the second phase comprising a coalescing operation to construct a set of coalesced reads of the downloaded data blocks;
• creating the local consolidated patch file using the downloaded data blocks;
• and
• storing the local consolidated patch file in a local storage.
