I have a Veeam B&R server with several jobs configured. When editing the job in Edit -> Storage -> Advanced I can configure to create a full backup periodically, let's say every saturday of every week of the month, such as the image below:

But in the Schedule tab Edit -> Schedule I can also configure the schedule of the jobs and let's say I don't want any synthetic backup, just the full backups periodically as it shows:

So my question is, even if in the "Next Run" section shows <Not Scheduled>, will the periodical full backup be done? At what time? If not, is there any other option to make just full backups automatically and periodically?
And last question, what if I have scheduled jobs from monday to friday at 17:00, but I want to make full backups on saturdays as stated before? Should I tag the saturday as a backup day or should I leave it untagged?
Thank you in advance and sorry for so many questions at the same time.
