my initial backup, around 3 Gb, will get "stuck" after partial completion....how do I resume.  Manage tasks shows backup either "waiting" or  "ready", but I don't know how to start it again....
any help appreciated...thanks.

You can select a backup task and click on the Start or Stop button.

when i restart it starts over instead of resuming...error codes that stop backup seem to all be related to symantec, so i turned off virus and spyware protection and see if it completes this time...
