Methods and systems for improved backup performance

A non-transitory computer-readable storage medium, comprising program instructions, which, when executed by one or more processors of a computing system, perform a method comprising:

• generating representational information, wherein the representational information is based, at least in part, on at least a portion of information of a top-level entity that includes a plurality of objects which include at least one new data segment or at least one modified data segment;
• retrieving a stored representational information, wherein
• the stored representational information is based, at least in part, on the at least the portion of the information of the top-level entity,
• the stored representational information is retrieved from log information produced as part of a backup operation, and
• the backup operation produced a backup image of the top-level entity;
• determining whether the representational information and the stored representational information match, wherein the representational information comprises an INLINE directive and the at least one new data segment or the at least one modified data segment;
• and
• in response to a determination that the representational information and the stored representational information do not match, indicating that the backup image of the top-level entity is corrupt.

A computing system comprising:
