After
running for a while (couple of months) the zpool seems to get
"fragmented", backups take 72 hours and a scrub takes about 180
hours.
Are there periodic snapshots being created in this pool?
Yes, every two hours.
Can they run with atime turned off?
I'm not sure, but I expect they can. I'll ask.
(file tree walks performed by backups will update the atime of all
directories; this will generate extra write traffic and also cause
snapshots to diverge from their parents and take longer to scrub).

Thanks!
