Incremental vault to object store

A computerized system for managing incremental data backups on an object store, the system comprising a processor configured to run a module stored in memory that is configured to cause the processor to:

• receive first data representing a changed chunk of data in a revision of a data volume stored on a storage device, the changed chunk of data comprising data having changes from previous data of a previous revision of the data volume, wherein the at least one changed chunk is stored on the storage device in a format associated with the storage device;
• create a block of data representing a copy of the changed chunk of data on the object store as object data, wherein the object store further includes a previous revision block of data representing previous revision data of the data volume stored as object data;
• determine a previous index stored on the object store corresponding to the previous revision of the data volume, the previous index comprising at least one index page having entries, at least one entry corresponding to the previous revision block of data stored on the object store;
• create a copy of at least one previous index page of the previous index from the object store;
• and
• create a revised index corresponding to the revision of the data volume, wherein the step of creating the revised index comprises:
• determine the entry in the revised index page corresponding to the previous revision block of data, and
• update the entry with updated entry data representing the change block of data,
• such that the revision of the data volume is retrievable from the object store using the revised index.

A non-transitory computer readable medium having executable instructions operable to cause an apparatus to:

• receive first data representing a changed chunk of data in a revision of a data volume stored on a storage device, the changed chunk of data comprising data having changes from previous data of a previous revision of the data volume, wherein the at least one changed chunk is stored on the storage device in a format associated with the storage device;
• create a block of data representing a copy of the changed chunk of data on the object store as object data, wherein the object store further includes a previous revision block of data representing previous revision data of the data volume stored as object data;
• determine a previous index stored on the object store corresponding to the previous revision of the data volume, the previous index comprising at least one index page having entries, at least one entry corresponding to the previous revision block of data stored on the object store;
• create copy of at least one previous index page of the previous index from the object store;
• and
• create a revised index corresponding to the revision of the data volume, wherein the step of creating the revised index comprises:
• determine the entry in the revised index page corresponding to the previous revision block of data, and
• update the entry with updated entry data representing the change block of data,
• such that the revision of the data volume is retrievable from the object store using the revised index.
