Microsoft Hyper-V • Large Backup copy Job - Overlap primary Backup

Hi

I have set up backup copy jobs to move backups to our OffSite NAS. This works fine and timely for the smaller VMs.

However we have one larger VM of about 35TB. The copy job will need about 15 days over the 400mbit connection.

backup copy Job:
Copy VM 01 to Offsite -> direct mode -> prune mode, copy last restore point only

What will happen if the daily primary backup job of that VMs runs/Starts?
Backup VM 01 - runs daily at 01:00
Backup mode: reverse incremental
Keep restore points: 3

So what will happen every night at 01:00 when the primary job runs? - from the help section I guess the backup copy will be paused when primary backup starts nad is running - correct?

What will happen when the primary backup has finished and hour or two later? - will it restart completely as the the last backup file has changed, (reverse incremental), it might never finish?

Will it know what has changed the last two hours and account for that? - after 14 days, will it have the copied the restore point from 13 days ago when I started the copy or the "current" one due to "awareness" what has changed? (3 restore points in primary are only 3 days, so primary wont keep data for 13 days...)

thx
