Transfer speed between geo locations

[staun]

We have a site in Asia that have a BackupCopy job which send the backupcopy to a location in Europe. But the transfer rate is a little to slow I think. Perhaps someone have a good explanation on where I should look.

Both Sites have a 100 Mbit internet connection, but transfer rate is only between 500 KB-1 MB/sec. and read speed is 1-2 MB/s

Any good ideas what to look for?

Hi Jørgen, first of all, what are the bottleneck stats for that job?

[staun]

Hi and thank for replying..

Bottlenecks differ a little, but aprox. the same status...

Load: Source 59% > Proxy 1% > Network 27% > Target 0%
Load: Source 66% > Proxy 1% > Network 32% > Target 2%

What kind of storage do you have at the source? How is it added to Veeam B&R? Are there any parallel tasks assigned to it while backup copy is running?

The backup server on source location is a HPE DL380 G8 with a HPE P2000 G3 Direct attached storage.

The storage is added as a Windows Server SMB3 repository.
(I tried to copy a 5GB file from local SAS disks to the target (to rule out the P2000 storage) and that is the same transfer speed. So I guess its not veeam that causes the issue

I have checked for any parallel transfers but that is not the case.

Bottleneck source means that the source data retrieval speed is the bottleneck. Since your test also shows the same data transfer speed, I'd test with some other server as a source to confirm the backup server itself is the culprit here.
