Hi, after some testing our side, i notices that cloud restore of full device is WAAAAY TOO SLOW. For example I started one restore from cloud 2 days ago (with tibx of178gb), and after over 40hours is only at 76%!

Local backup of same device/archive was restored in less than 45 minutes.

We also noticed that with the cloud restore the connection bandwidth is not fully used, same for disk and cpu usage.

Calculated download time of the tibx based on www.speedtest.net/it should be 11 hours and half, and based on https://cloud-wr-eu2.acronis.com/speedtest/ 17 hours, but after over 40 hours the restore is still at 76%...

We also did acronis speed test with different connections and noticed that is always near half of the other speed test (that is near effective speed instead). Maybe acronis datacenters have limited resources or maybe there are some routing issues to italy...

I also thinked to workaround this problem by downloading the tibx and restoring it locally but it seems not possible.

For critical cases where only cloud backup is available, lasting 2-3 days to make a cloud restore of 170GB is litterarly UNACCEPTABLE.

This issue seems to be present with both windows and linux, with different acronis version, with both tib and tibx (even for previous restore cases I've not taken exact time). Restore times seem to be always N times higher of (computed) download time for the archive's backup size...

Anyone on this?

Thanks for any reply.

Hello Emilio,

 

It's Evgeny from Acronis Service Provider Support. 

As far as I understand you have faced an issue with the slow recovery of a disk-level backup (entire machine) from Cloud.

 

I would like to begin with the confirmation that the recovery from the Cloud is expected to be slower than the local recovery that you have observed. Having said that, I understand that 2-3 days compared to 45 minutes cannot be used as a proof that the situation was expected. We need to find the bottleneck of this issue to state any assumptions on the root cause. 

The speedtest results basically show you the connection speed and it is a good measure in terms of general connectivity or file download, but in case of an entire machine backup the speed is always going to be lower than the speedtest result. Take into account the I/O operations, the latency through all the network hops. 

Still 178GB over 40+ hours is not an expected result. The tibx (format 12) has large improvements to the speed of backup/recovery operations than the TIB type (format 11). It is sad that you don't have the results of previous restores, but I am sure the tibx recovery is faster. 

To understand why the slowness is present, I suggest you check the bootable media recovery:

https://www.acronis.com/en-us/support/documentation/BackupService/index… 

Knowing the results of the recovery speed from the bootable media might give us an idea whether the issue's bottleneck is within the OS way of managing the recovery (you wrote that similar results are both on Linux or Windows, bootmedia is a busybox system and is an alternative to try).

If the speed is relatively slow too, we might need to take a look at the logs collected after the recovery was running for some time. 

Additionally, once you contact us with the logs through the standard support process, we will be able to suggest on how to download the file in case of urgent recovery need.

It can be  done by yourself with LSR tool - it requires some reading + installation of the tool, so please take a look.

 

We will be glad to help you with the issue investigation, in case you collect the sysinfo report and share the details with us per the template 

 

Have a nice day in the meantime.

Hi, thanks for reply.

Even if backup is in tibx format was completed in 2 days and 8 hours.

Here connection test with acronis: https://acronis.speedtestcustom.com/result/38749900-f160-11e8-95c7-dd56… - Around 70mbps is  the usual speed for other uses outside of acronis.

Here the restore log (restore was done from default bootable recovery media based on linux downloaded from acronis cloud backup web interface, like near all):

I not have time to do other tests now but for future ones any advice is welcome, thanks.
