Abstract: Examples include the persistent storage of cached data of a write to a block device presentation. Some examples may include a block device presentation of data represented by first backup objects stored in a deduplication backup appliance, and may cause the deduplication backup appliance to store second backup objects representing the data stored in a cache for each transient write to the block device presentation.
