Backup of SQL Always on Cluster

[rene@aksessikt.no]

Hi You'll

I've sett up a backup job of a AO SQL cluster. I followed documentation and everything went smooth.
Backup job runs well and backup copy works to.
I get just one warning, doesn't seem dangerous but I don't like unsolved warnings
It says that on my secondary node the job is unable to truncate the logs. I've been searching and found some good post's but non seem to answer my question.
I read it like that it's normal that the secondary node log isn't truncated, no problem but way is it trying? can I exclude it from the secondary node? Are the logs on the secondary node truncated in any way?
My setup is to virtualized windows 2016 servers that run inside a Hyper-V cluster I use SQL 2017 or version nr 14.0.2027.2

I greatly appreciate any comments that sheds some light

Regards Rene

Are you on the latest patch for Veeam? This was an issue but it should be fixed now, at least I haven't seen any warnings anymore on 9.5 U4b

Hi thx for your reply. it seems I'm using the latest yhat's not Beta my version is 9.5.4.2866
i think the logical cause for the warning is that the secondary node is read only.
Just checked it again Node 1 my primary is successful.
In the setup I followed VEEAM's manual and it shows up as a Windows Agent Backup
There must be a way to suppress this warning, hope there's a VEEAM engineer monitoring this thread.

Hi Rene, are we talking about Basic Availability Groups? Also, you are mentioning "Windows Agent Backup" but you're using Veeam B&R 9.5.4.2866 to backup the SQL cluster, right?

Yes this is a basic availibilty group with to SQL servers as a member. SQL is installed on a virtualized windows 2016 server that's setup as a 2 server cluster.
I just followed the instructions I found from VEEAM. There it said I had to creat an AD protection group, both servers are part. It automatically installed the windows Agents. And yes I use VEEAM B&R a 6 processor licens

Seems you're mixing up two products here. You do not need Veeam Agent for Windows in this setup, you can back up these virtual SQL servers using Veeam B&R.

THX i was afraid I did but it said so in the manual VEEAM made for this and it installed the agents from inside VEEAM B&R it was no choice i made or an installation I did separate.
The manual told med to add an AD protection Group under Physical Cloud Infrastructure. There I added my MS cluster object (that has 2 nodes) When I get to Options it asks me to pic a distribution server and has tagged Install backup agents and auto update. After i said I was happy and clicked apply it installed the agents on my Nodes.
And as i said it works it's just annoying that on my secondary node it gives a warning that it cant purge the SQL logs (which is not possible since they're read only.

BTW this is the KB or Manual I used https://www.veeam.com/kb2463

if you can plz point me to the right KB or documentation so I can correct my error.

Hi Foggy.

just found some more articles veeam-backup-replication-f2/backup-sql- ... 40892.html
Seems that this a know issue that VEEAM will address in V10 or did I interpret the article wrong?
