Abstract
Example implementations relate to computer data storage. In some examples, a filesystem scanner identifies files in a filesystem, where each file comprises logical blocks, and where the filesystem is included in a backup. The filesystem scanner generates a read buffer to store a logical block of a file. A block filter driver determines that the read buffer includes a predefined signature, and in response determines whether the logical block was modified in the backup. In response to a determination that the logical block was modified in the backup, the block filter driver sets a modification flag in the read buffer to a value indicating that the logical block was modified.
