Some questions about Backup Options

In the Backup tab, under Options, it says: ‘Enter the options for this backup command when run manually’. All I can find in terms of info on this is @ Backup command details

There are two fields:

  • Command options
  • Global options

I have a few questions.

  1. How do you combine several options, do they need to be comma separated or something?
  2. If I were to want to add ‘-vss’, would that go under ‘Command options’ or ‘Global options’?
  3. Should I add ‘-vss’? I am a translator and will be using Duplicacy to upload my data every hour or so, and some of it will be in programs I am using. If I don’t select ‘-vss’, does this mean data in open programs won’t get backed up?
