A snapshot of a volume is taken by proactive uploading of scheduled snapshot data before the scheduled snapshot time has arrived. A volume snapshot schedule of once a day may be set up to a service provider using a speed-limited network connection. Using a determined upload speed of the network connection and a list of changes to the volume since a prior snapshot, a snapshot system may determine an appropriate time to start uploading volume data so that the snapshot may be completed at or after the scheduled snapshot time. By using the list of changes and available bandwidth of the network connection, the snapshot may be completed earlier than had it been started at the time of the snapshot and the available bandwidth of the network connection may be more efficiently used.
