Backup over network fails

Post by brandonids » Jul 25, 2018 7:49 pm

I know you're supposed to have a support case ID but, we are currently in a trial with Veeam to see if we are going to use it.
There are several hosts on 6.5u1 with local storage, and I can get them to backup when using a proxy set for VA[hotadd] mode.
However, if I have the failover to network box checked, or if I try and use a proxy that is just set to network, the backups fail.

Code: Select all

Error: Object reference not set to an instance of an object.
[25.07.2018 11:04:01] <26> Error    Object reference not set to an instance of an object. (System.NullReferenceException)

[25.07.2018 11:04:01] <26> Info     Notifying other disks about error
this is what I see when failover to network or pure network proxy is used.
I get the following when using a pure hotadd:

Code: Select all

[25.07.2018 11:05:22] <20> Info     [NbdCompression] The specified transport does not support compression.
I thought the network was supposed to be the easy one :( I've noticed that the jobs also use VDDK 6.0 with a warning about reverting to default.
Since NBD Compression wasn't added until VDDK 6.5 I'm wondering if there is a disconnect there somewhere.

Even though you're in a trial period with Veeam, I would suggest contacting Veeam support anyway. You have nothing to lose and a lot to gain.

The worst they'll say is "no" but Veeam is pretty good at assisting users, especially (I assume) potential customers.

Whatever the outcome, post your results!

Good luck.

Barely can we help you here without seeing debug logs and your environment. So, kindly, reach our support team for further assistance.

Nitramd is correct - even owners of trial license are eligible for support.

Thanks.

Veeam does offer evaluation support at best effort level. Just open a case via your Veeam account and I'm sure you'll receive assistance.

Edit: Too slow ;)

Thanks. It looks like that was the issue. I noticed there was 9.5u3a out and updated to that and it is using vddk 6.7 now instead of 6.0 and things are working as I would expect.
