Backing up SYSVOL issue

So i’ve been all over the forum and I see some similar issues, but everything is so old I don’t think they apply any more. Many of them are fixed by upgrading… I’m all the way upgraded. I’ve been trouble shooting this the last couple of weeks and I’ve gotten no where. I have several servers being backed up to a single Urbackup box running on Ubuntu 20.04 using ZFS. I only have issues with one client. The client is Server 2016 (its not the only server 2016 I’m backing up either). I have wiped all previous backups out of the Urbackup server and reinstalled the client several times… all to the same result. So I thought I would try you guys out for a fix. Here is the Debug log from the client:

2021-08-10 08:20:16: ERROR: Backup failed

This is an internet client… but its the exact same setup as four other clients. So i know its not a firewall issue, and it shows connected. And other than a backup… the logs are clean for it. Has anyone had this happen? I tried to pull the client software and wipe all registry entries and reinstall to the same messages. I’ve wiped all the existing client backups in the server to make sure I didn’t have a mismatch that was screwing this up. I’ve checked ports and firewalls. I have 7 other machines backing up to this server (1 Server 2019, 3 Server 2016, 1 Server 2012, 2 Windows 10) I have no issues with any of them backing up correctly (only the Server 2019 and the Windows 10 machines are local to the server btw). I have a local backup that runs on this server (it doesnt run at the same time) that has no issues. Sysvol backs up without issue. The other weird part is that this used to work… unfortunately i dont watch this server that closely as its just my fail safe backup… so I’m not exactly sure when the backup started failing and I havent gone back in the syslog far enough to find it… but it used to work fine. I’ve done the usually checks on the windows file system and don’t see any glaring issues. Any help would be appreciated. Also I tried to clean up passwords and names… if i missed something let me know so I can edit.

It seems to get a WSAECONNRESET relativly fast, probably while sending from the client. I’d narrow it down by disabling compression and perhaps encryption.

I’ll give that a shot today and let you know the results.

Would this have anything to do with holding libcrypto++6 to version 6_5.6.4-8? I had to hold this previously because encryption wouldn’t work if I upgraded it. I thought holding it was still required because my other servers are still working correctly. Also no changes in the log… I disabled both ecryption and compression and I still have the same result. Are there any other logs you want to see or that might help? I’m lost as to whats happening with this system.

I do see a lot of errors but not sure what to make of them…

So it doesn’t help… If you want to further investigate. Try and watch the TCP connection via WireShark. Then the (client) software side via ProcessMonitor.

If you have any drivers that hook into the network stack (such as firewall software), try to disable them :wink:

Well, I don’t know what to say… I’ve rebooted this server (the client) about 10 times during all this, and got the same result. I had to reboot (the client) for windows updates last night… and it started working. I mean as soon as it came back up it autostarted a backup! I’m wondering if something got broke by an update and another update solved the problem, which would be like finding a unicorn! In any case its fixed! and I’m sorry for wasting your time, but thank you for trying to help me!
