If your connection is interrupted, ZCB will immediately begin to actively retry the upload, and will continue to retry for approximately 11 minutes. After that time, the upload will be marked as failed on the Report page.
After an upload fails, ZCB will continue to retry the failed upload in a more passive manner. Schedules are created in the Windows Task Scheduler.
The exact behavior depends on which version of Windows is installed.
ZCB will attempt to resume the upload once every hour.
The upload will resume automatically when ZCB detects a network connection.
