Slow Veeam Backups - calling Veeam and VMware experts

[Kdes]

Good Day Everyone

I please need help to investigate a problem I am having with Veeam Backups.

The company bought Veeam 9 and while installing we came across a backup speed issue on production DL380e G8’s. They running ESXi 6. Backup speeds we get is 35MB/s odd.

We setup a test environment to test with, we have;
1 i3 Desktop running VMware ESXi 5.1
1 DL380 G5 running VMware ESXi 5.1

Both are being backed up with a physical Veeam 9 backup and replication server.
Target is a QNAP NAS connect via ISCSI to the Veeam Backup server.
Each ESXI host has one Veeam Proxy and one test VM for backing up.
The VMS are stored on the local storage of both hosts.
All connected to same switch in an isolated network all nics connected at 1000Mbps.

Here is the thing.
Backing up the VM from the Desktop ESXI we get ~99MB/s
Backing up the VM from the DL380 G5 ESXI we get ~40MB/s

So on the test environment we also get slow backup speed of around 40MB\35MB/s as we do with the production environment.

Does anyone have any idea what this could be or perhaps suggest what we need to investigate?

Thanks

Is your physical backup server on the same lan segment as your MVWare Management network?

And in the job, what's the figures:
Load: Source ? > Proxy ? > Network ? > Target ?
Primary bottleneck: ?
Fill in the ?

 

[irBosOtter]

Oh and what's the speed like if you just use the physical server as the proxy instead of the VM proxies?
And what transport mode is set for the proxies?

Hi Kdes

The correct process is that you need to log a Veeam Support request either by going to www.veeam.com/support or by calling +27 10 500 79 63.

Thank you for the replies.

The DL380e G8 reports bottlenecks as Source 99% Proxy 18%, Network 3% Target 0%.
The desktop job reports bottlenecks as Source 91%, Proxy 37%, Network 27%, Target 0%.

Seems to be that the it is a problem trying to read the VMDKs from the data stores.

We did go to veeam support and they could not help to much as it seems to be a problem reading the data.

Can you post more details of your RAID config of the DL380's? What disks & controller? RAID level? BBU present and enabled? Volume groups in write back mode? Controller read ahead settings? Stripe size?

Is CBT (changed block tracking) enabled?

Is CBT (changed block tracking) enabled?

This.

 

[irBosOtter]

Check that CBT like the other guys said and if it's enabled (should be by default) do a reset on it and see if it helps

And the transport mode, what does it say after the disks being processed?
[hotadd] - Should be used in your case with the VM proxies on the same local storage
[san] - N/A for your environment
[nbd] Will failover to this if there are issues with hotadd and will be slow
