10gb backup only managing about 80Mb
-
What kind of backups are you using? In general, the bottleneck is within the export speed per disk (or if you do full backup, compression can be a factor)
-
Continuous replication.... runs every 12 hrs...

@olivierlambert ok here's a bit from the log.. Start: 2025-09-03 12:00
End: 2025-09-03 12:00
Duration: a few seconds
Size: 624 MiB
Speed: 61.63 MiB/sStart: 2025-09-03 12:00
End: 2025-09-03 12:00so other jobs are sowing anywhere betwwen 25 to about 80. MiB/s
What CPU are you using? We saw about the same speeds on our older Intel Xeon's with 2.4ghz and when we switched to newer Intel Xeon Gold with 3Ghz the speeds increased quite a bit, we're now seeing around 110-160 MiB/s after migrating the XO VM.

I would have ask the same question

My hosts are Hp Elitedesk G5 SFF.. 64gb Mem Processor type is Intel Core i5 3.0Ghz i believe.. nics are showing connected @ 10GB

IDK if the BIOS provides many power options, but you could make sure you are turbo boosting when needed. Because it's likely your CPU is both old but also not getting at 3Ghz at all.

Great minds and all that, you know
@utopianfish check if you have any kind of power options regarding "power saving" or "performance" modes you can change in the BIOS. That could make a big difference as well.

@nikade i think the problem is its using the mgmt interface to do the backup..its not touching the 10GB nics.. when i set it under Pools/Adanced/Backup to use the 10gb nic as default the job fails... setting it back to none the job is successful with a speed of 80 MiB/s.. so using the 1GB mgmt nic... how do i get the backups to use the dedicated 10gb link then. ?

Use XO to connect on the host with the 10G network IPs addresses.

May I ask why your management interface is not on the 10G nic? There is absolutely no downside to having that kind of setup.
We used this setup for 7 years on our Dell R630's without any issues at all. We had 2x10G NIC in our hosts and then put the management interface on top of the bond0 as a native vlan.
Then we just added our VLAN's on top on the bond0 and voila, all your interfaces benefits from the 10G nic's. -
That's also what we do in our prod.
