pve version: Virtual Environment 8.4.1
When backing up a VM from a local zfs stripped mirror 2 x 3 nvme drives (so i am assuming here is no bottleneck)
At about 47% of 64GB the transfer slows down to a crawl. It happens each and every time I make a backup, of any VM. This time is is not longer continuing.
The network seems fine as I can move files around between clients and also to and from the backup share with great speed.
What steps can I take to find the culprit?
