Abstract:
A method includes initiating committing to persistent storage of a current consistency snapshot of a plurality of data objects in a redirect-on-write file system. Each of the plurality of data objects has a first copy of at least two copies of the data having a first context of at least two contexts. The method includes receiving, during committing to storage of the current consistency snapshot, an update to a data object of the plurality of data objects. The method also includes responsive to receipt of the update to the data object, creating a second copy of data of the data object from the first copy. The second copy of the data has a second context of the at least two contexts. The method includes responsive to receipt of the update to the data object, updating, based on the update, the second copy of the data of the data object.
