Veeam.Backup.AgentProvider.AgentClosedException, #01674090

Veeam Logoby rreed » Fri Jan 22, 2016 6:58 pm

Afternoon, all. Fresh v9 install on a fresh VM. Removed a few existing proxies from our old v8 setup, added to our new v9 server (upgraded agent, installer, etc. successfully). Disable old job on old server, build from scratch on new, map backup to existing backup files on repository. Sees everything fine.

Random jobs fail w/ "Error: Exception of type 'Veeam.Backup.AgentProvider.AgentClosedException' was thrown." Case #01674090 being worked, log files sent, etc. A few things found in logs pointing to Oracle servers and VMware workstation, neither of which do we have here.

CBT has been reset, file locks, temp data, reboots, etc. No change. Anyone else seeing this in a fresh install/migration of v9? Searching shows up some old hits from way back that don't appear relevant to our case.

Having been going on from the get-go, after a handful of days now it seems it happens more frequently w/ some VM's than others, but overall still a bit random.

So far have narrowed this down to a bad proxy. Working w/ support and continuing to investigate.

Confirmed ours was just a bad proxy. Uninstalled/re-installed all Veeam agent, etc. still no good. I'll be wiping the VM and re-cloning a fresh one.

Afternoon, everyone. This error has come back again, and after opening another case (#01697389), apparently is was mostly just because one of our Data Domains was having another episode of not authenticating any connections.

In v8, we'd see a very clear "bad username/password" in the job status and subsequent report. Easy, just reboot the DD and be on our way in about 5 minutes. In v9, I see "Veeam.Backup.AgentProvider.AgentClosedException" is now its generic error when something fails, leaving me to comb through log files to find what the problem is rather than giving something useful at the console/emails/reports. Errors/issues so far have not been isolated to a single storage device needing a reboot, we've had other misc. issues since v9 that throw "Veeam.Backup.AgentProvider.AgentClosedException" whereas v8 would have given some hint at least. We lost a night or two of backups because I thought this error was somethign more serious than our stupid DD's being themselves; I could have rebooted it had Veeam thrown it's useful error.

Do we have some sort of generic alert turned on in our bone stock v9 install? Is there a switch I can flip somewhere that will replace the AgentClosedException error w/ its previous more useful information when something underneath fails? Hate to complain, but it's costing us more time and lost backups when we have to go chasing around log files, investigate, etc. rather than know right away what I need to go do to fix it.

In our lab, in case of insufficient permissions v9 correctly reports this event in the job log. QA briefly looked into your logs and apparently this does not come down to DD authentication issues only. There are multiple other access issues in the logs where DD is not involved (for example, when source agent connects to VMware). So seems like there are more global authentication issues in your environment and I recommend looking deeper into this with the help of our support engineers.

Thanks foggy. So if I understand correctly, we're getting "Veeam.Backup.AgentProvider.AgentClosedException" in the status/reports because we have a permissions issue, regardless of the underlying cause (naughty DD, proxies actively refusing connections, etc.)? And yes sir, I'll open up a new ticket right away.

Cannot comment on what specific reason is behind this particular message, logs should tell.

Same problem here. I disabled the proxy on the veeam server and added an extra proxy. Let's see what happens next.

Just checked all backup jobs from the past weekend. After friday's adjustments all jobs went ok. So next question is how to repair the veeam backup proxy? I had to switch to this server because the old server (2008R2) didn't support the exchange filesystem. I moved all jobs from the old server to the new. Worked fine for one week till this problem occured.

As a first step you try to re-install required components by removing and re-adding the proxy role to the given server. If this doesn't fix the issue, you'd better open a ticket with our support team and let them confirm your environment. Thanks,

Case# 01872048
B&R v 9.0.0.1491
Server 2012 R2

Backup (7TB) and backup Copy (based on same backup). Backup copy was seeded initially and worked for about 2 months.
Randomly fail with:
1) Source WAN accelerator error: Socket recv operation timed out
2) 'Veeam.Backup.AgentProvider.AgentClosedException' was thrown

While backup will complete occasionally I haven't gotten a viable backup copy of it off site in over a month. I have removed proxies as suggested in previous posts and thought that did the trick, but it has returned.
