Abstract
In some examples, a computing device stores root metadata data structures (DSs) together in a group root metadata filesystem block, and stores, in a data filesystem block, at least first file data referenced by the first root metadata DS and second file data referenced by a second root metadata DS. The computing device may determine a reference count of the data filesystem block based on the first file data referenced by the first root metadata DS and the second file data referenced by the second root metadata DS. In addition, the computing device may determine a third file data having content that matches the first file data and referenced by a third root metadata DS. The computing device may update the third root metadata DS to reference the first file data, and update the reference count of the data filesystem block based on updating the third root metadata DS.
