The back is several muscles that do different jobs, so one exercise is never enough. This session pulls from above for the lats, rows for the upper back, and finishes with the lower back.
With a full gym you can open with a heavy barbell lift and finish on cables and machines, which let you push close to failure without technique being the thing that gives out.
Sets per muscle. A muscle that only assists in an exercise counts half.
How to run it
Before the first exercise, do two lighter sets of it: one at about half your working weight and one at three quarters. Rest for the time shown next to each exercise; the heavy lifts at the top need more than the smaller ones at the end.
Aim to finish each set with one or two reps left in you. If every set reaches its target easily, the session is too light. Add the smallest plate you can to the barbell lifts, and move up one pin on machines and cables once every set reaches the target.
Once or twice a week. Leave a day between this and any session with heavy deadlifts or squats, since the lower back works in all three.
If something is taken
Keep the same number of sets. In the app you can swap an exercise for one session without changing the program.

Logging is free for good. The first 14 days also include Pro, where a coach reviews each session and suggests the weights for the next one. No card needed.
Questions
About 50 minutes. That is 20 working sets with the rests listed next to each exercise, plus five minutes to warm up.
Mostly the lats, upper back and biceps. The lower back, forearms, abs and glutes assist. The map on this page shades each muscle by the number of sets that reach it.
A full gym: barbells, dumbbells, cables and machines.
Vertical pulls: pull-ups, chin-ups and lat pulldowns. They train the lats, which are what give the back its width.
Use rows that take the lower back out of it, such as a chest-supported row or a seated cable row, and keep the weight where you can hold a flat back for every rep.
