For the second time in two days backup is stuck at 90 or 91 percent. Software is running, but the backup job is stuck in concrete. I restarted veeam, I restarted veeam services and backup server, nothing helped, its stuck. I have two servers to backup. yesterday backup was stuck in win2012r2 exchange server backup; today its the win2016 fileserver. today veeam backuped the data disk successfully, but the system disk not. the exchange server is on the system disk. maybe that info helps. it seems to be a problem with backuping windows (and not data).
V12 Backup stuck in 90 percent
Best answer by Chris.Childerhose
I did another test backup today without changing the configuration yet. Everything ran smooth and no backup got stuck. What I reconized was the low processing rate and a cpu load of sometimes 100%. Veeam services did cause some load, but each service not more than 5 to 15%. The highest load was caused by MS antimaleware service… I will monitor the next backups and report. When a backup job gets stuck again, I will reconfigure the proxies as adviced.
One question about the proxies: Did I get that right, I have to change the transport mode from automatic selection to “virtual appliance”? And Chris, you ment that I should setup a new VM machine to be the proxy besides the backup server or did you mean i should setup a new VM proxy within Veeam? Thankes a lot so far and in advance :)

I meant you need a new VM to be the Proxy and configure it with 8 vCPU and 32GB of RAM - that is Best Practice configuration. Then in the console you add this new server to be a VMware Proxy and then if needed change the mode for the Proxy - it will set to Automatic and try Hot-Add/Virtual Appliance mode first then failover to NBD if needed. You also then disable the Veeam server in the Proxy section from being a VMware Proxy that way it can manage things as it needs to be.
Also, I would put exclusions in the MS AV as per here - KB1999: Antivirus Exclusions for Veeam Backup & Replication
