N-Way Synchronization/Backup (Synk Pro)
Synk Pro can use multiple sources for backup/synchronization. You can add additional sources via the "Add" button in the "Folders" tab. Sources can be deleted via the metallic "X" on the left of each source entry.
The multi-way arrow button next to each source determines the type of operation (backup/synchronization). If a source is selected as master, then its contents will be backed up to every other source. If no source is set to be the master, then all sources will be synchronized.
