You can easily choose which folders should be backed up from within the inSync client.
The procedure may differ slightly between client versions, and you may want to consult the inSync client User Guide, but should be similar to the following.
Open the inSync client
- To Add a Folder: Click on "Configure" > "Advanced Configure" > "Add Folder" > "Choose path" and select the folders you wish to backup.
- To Remove a Folder: TBD
Open the inSync client and you'll be presented with a list of backup folders.
- Choose the Add button to add folders to be backed up.
- Non-mandated folders may be removed by clicking the cog icon to the right of the entry and choosing the Delete Backup Folder Button.
