we have 1 backup copy job which "offsiting" about 70 vms and is working 8-20 and i have problem cause when it works it take all resources . So when i need start manually any backup this time (8-20) its start and automatically end with msg "waiting for resources". Is any hidden registry key or hidden option to limit that backup copy job ..somehow like work for 100% but when some other backup/replica job appear let it also works
My mistake, it slipped out from my mind that it's a backup copy job. Proxies are not involved in Backup Copy Job - traffic flows directly between repositories. So please check what's the maximum concurrent tasks limit on your source and target repos. You backup copy job cannot process more disks than specified in "concurrent tasks limit". Do you have WAN accelerators by any chance?
