Optimum TCP settings for Cloud Backup

Thread needs solution

Please tell me if there is a better place for this question.

Are there optimum settings in TCP or the ethernet adapter to achieve best throughput when running regular backups to the cloud?

I have a Thinkpad T560 running Win 10 Pro 64 1909 and Acronis True Image 2020. The backup runs over ethernet via the TPad’s Intel Ethernet Connection I219-LM adapter. My internet link is rated up to 30 Mbps. The Windows Task Mgr tells me the backup runs at a “bumpy” low to mid teens Mbps, quite a wide margin below the internet connection speed.

Are there settings other than the defaults on the adapter or in Windows TCP that will speed things up? I recall vaguely there used to be more discussion of TCP settings many years ago, but I have not paid attention to the subject for a long time. My TCP knowledge is middling and probably out of date! I can see many settings one could modify in the adapter properties.

Thanks

David, welcome to these public User Forums.

When you say that your internet link is rated up to 30Mbps, is this just for Download or for Upload or for both?

Most internet providers give much faster download speeds than they do for upload, i.e. for myself, my download is rated at 100Mbps but upload is only 10Mbps!

The actual upload of data from ATI performing a backup to the Acronis Cloud will never be a totally smooth process as ATI is doing a lot of processing on that data before it then prepares packets to be uploaded.

There are very few, if any, TCPIP parameters that can or should need to be changed on Windows 10 systems as this is handled by the OS.  This was something that users may have done in the past with much older versions of Windows but those days are long past.

The key decision with regards to backing up to the Acronis Cloud, is to ensure that you have selected the closed Acronis Data Centre to your geographic location, simply to minimise the distance that data has to travel across the internet.  This can only be done at the time that a task is created and cannot be changed later without making a whole new task!

See KB 4350: Acronis Backup to Cloud access ports and hostnames - for details of where all the servers are and what ports they use.

Use the above in conjunction with the Acronis Cloud Connection Verification Tool.

Thank you, Steve, for your answer.

Importantly, you answer that there are no TCP settings I should worry about.  OK

Do you think that also applies to the ethernet adapter settings?  The properties page for the Intel I219LM lists several parameters I vaguely remember from the distant past, such as jumbo packet (disabled). (I am 25 years retired and was never that strong on telecoms)

My internet connection is unusual.  To overcome the problems of long copper lines in this rural area, a company has st up a wireless based service.  Via dish on the house wall I am connected to the company's aerials on a tall tower some 8 miles away, and thence eventually into the UK backbone.   Speedtest.net reports 25 - 30 Mbps typically in both directions.

I had not specified a server when setting up the background.  If I take the defaults when defining a new backup it appears to be France, with choices of Australia, Germany, Japan, Singapore & US - but nothing in the UK.   Yet the list of data centres you mention includes London.   What gives??

I then tried the Acronis cloud check programs.  EU2 tests a long list of IP addresses and reports success in all.  EU3 flashes briefly at me and then does - nothing.

So puzzles there.

David, you should be able select the United Kingdom data centre when setting up a new cloud backup task.  I am not sure why some UK users get defaulted to using the servers in France - I have been caught by that myself and try to remember to double-check the setting when making a new backup task!

I would say that the Ethernet settings should be left as they are too and any adjustments for your specific connection scenario should be handled by the equipment being used to provide that connection transparently to your computer.

David,

Here's a link to the latest on troubleshooting network connection performance covering both WAN and LAN.  You might find it useful.

Thanks for this. I had the same problem with the backup speed. This guide helped a lot
