Further, the computing device may determine an ingest speed based on a quantity of data received by the first storage system and a copy speed associated with one or more first computing resources associated with the first storage system. The computing device may determine an estimated time to copy at least a portion of the pending data to the second storage system to meet a data copy requirement. For instance, the estimated time may be based at least in part on the copy speed, the amount of pending data, and the ingest speed. In addition, at least one action may be performed based on the estimated time. ## Claims ### Claim 1 A system comprising: one or more processors configured by executable instructions to perform operations comprising: determining an amount of pending data to copy over a network from a first storage system to a second storage system to meet a data copy requirement specified for the pending data;
