Provided are techniques for providing and managing data protection by using incremental forever for storage to cloud object stores. An incremental offload is performed by using one or more extents to identify blocks of data for a version of a virtual machine in operational recovery storage to be offloaded to a cloud object store, wherein each of the one or more extents identifies locations of the blocks of data. The blocks of data are converted to objects in an incremental forever data format. The objects are offloaded to the cloud object store. The details of the offloading of the objects are stored in a local database in the operational recovery storage. The local database is copied from the operational recovery storage to the cloud object store as a database copy.

Providing and managing data protection by using incremental forever for storage to cloud object stores

A system and method to efficiently back up files while preserving memory resources. The system includes a generation module to generate an unordered list of backup files and associated attributes, and a processing module to back up local files one at a time by modifying the backup files to reflect changes to the local files. The processing module may include a retrieval module to retrieve local file attribute information from the hard disk, a comparator module to compare the local file attributes to corresponding backup file information on the list, and an update module to update the corresponding backup file to reflect any differences. In this manner, the present invention avoids processing limitations caused by insufficient memory and/or excessive quantities of local files.
