Trying to understand scheduling, have read some, but need to have it in with a spoon

If I want a backup job to only take 1 full backup each week on Wednesday, is this how it should be solved ?
1. Create a backup job, configure it with incremental, select "create synthetic full backups periodically" and select Wednesday
2. Leave retention policy as 7 days
3. On the schedule screen, select "Daily on these days" and select Wednesday
And....
From the job above I would also like to make a Backup-Copy-Job to another location, where it should only store GFS.
Should I then just select it like this picure ?
