Some examples provide a system including neighboring computing devices comprising a deployed operating system (OS) volumes, and respective neighboring bit tables corresponding to the deployed OS volumes. The system may include a target computing device comprising a target operating system (OS) volume. The target computing device may determine a target bit table corresponding to the target OS volume. Each bit in the target bit table indicates whether the data block of the target OS volume differs relative to a base OS volume. The target computing device may determine, based on bit tables, a first set of data blocks that are identical to a second set of data blocks of the deployed OS volumes. The target computing device may receive the least one data block in the second set of data blocks from the neighboring computing devices, and assemble the target OS.
