Abstract: Examples described herein relate to deletion of data entities in a deduplication system. Examples may maintain entries in a housekeeping queue, each entry including a priority value and a total unshared chunk size of a data entity to be deleted from the deduplication system. Examples may delete the data entities corresponding to the entries including a low priority value from the deduplication system. Examples may determine whether an available storage capacity of the deduplication system is sufficient after deleting the data entities corresponding to the entries including the low priority value. Examples may delete a data entity corresponding to an entry including a high priority value and a largest total unshared chunk size if the available storage capacity is insufficient.
