In addition to this, let me ask the following as well:
Say you dont tick the box to "pause" the actual backup job, will both tape out jobs and backup job then run at the same time? Does the tape out job also start by backing up the oldest points in the backup chain and then work its way up to the most recent restore point? If that's the case, that means you can run both backup and tape out job together, and once the backup chain starts to replace the oldest restore points based on date, you should already have that sitting on tape if the tape out uses the same sequence?
I am going to assume that is risky and you ultimately want the backup job paused so it can tape out a 1to1 of what you have on disk without issues in between, my problem there as mentioned before is the fact that you now run the risk of not running backup to disk jobs since its paused waiting for tape out to finish.
