Copy files slow

[adrianIDC]

Hello veeam community!

I'm in a situation where when copying files, the copy speed is very low. For example, to copy 3Gb it took 40 minutes!! when If I copy from Windows Explorer (copy-paste) takes 4 minutes.


I tried to copy from \\server \d$ to my local drive C, both \\server\d$ (example) to a removable hdd 3.0


This situation is normal or is there something wrong with my machine?

When I set the file copy, no option alone (source, destination, programming).


Regarding the backup of VM I have no complaint, makes fast.

Thank you very much for your time and help.

Hello!

Just to make sure: are you talking about File Copy job or Backup Copy job?

If we are talking about Backup Copy, there can be some reasons, since it has 4 phases, including transform operations. The transform operations can take additional time doing a backup chain transformation and/or removing deleted VMs from restore points and/or compacting a full backup file, according to it`s own retention policy, which can differ from the source Backup job one.

In a case of the File Copy job, the copying speed doesn`t look normal.
Thanks!

Hello Shestakov .
Thank you very much for your answer.

Work is Auxilary Jobs > File Copy.

As I said, the backup of VM are going well and are fast .

Assuming source and target are the same in both cases, you shouldn't see 8x difference. Thus, it might be worth opening a ticket with the support team and letting them confirm your environment. Thanks.

[Shestakov]

Agree, for the file copy job should have much better performance.
So, once you open a support case as Vladimir mentioned, please provide us the support case number to be able to follow the issue investigation.
Thanks!

Greetings Veeam community.
I wondered if there was a way to speed up a task Copy FIles removing Analysis processes or no way to configure this point that comment .

When many files, it takes too long.

Thank you very much.

[Shestakov]

Hello,
Could you provide File Copy jobs statistics showing what "Analysis processes" take in your case.
As far as I can see you decided to contact Veeam technical support to find out the reason of the slow jobs` runs. Have you contacted them finally?
Thanks!

[adrianIDC]

Yes, I was contacted and perfect .

Just wondering if there would be the possibility to configure avoiding copying files to make a preliminary analysis files.


I also note that only copying a file ( file type .ISO large 30GB ) if obtained a high- speed copy.
However if I need to copy many files scattered in folders , this is where I see the speed is really low.

[Shestakov]

"Pre-copying" activity such as file size counting and routing doesn`t take a lot of time in general and I don`t think file can copied without it.
Does the "analysis" take a lot of time in your case?
Once again please provide your support case number, so I could take a look at your debug logs with the dev team. Thanks.

This is the case number : 00832086

There is one last log is right but I previously got is what I say.
Upload date is the 17 - MARCH- 2015 .

Thank you very much for your attention.

[Shestakov]

Adrian, as far as I understood from the support case thread(last part is in Spanish), you did not reply to the last messages of the support engineer. May I ask why?
Please keep investigating the issue with the Veeam support team. Thanks.

Hello Shestakov .
I have already answered in the open case .

Thank you very much for your help.

As I commented on the case. If I compress files in .zip speed is slightly larger and less time. But if I do it with separate folders and files hosted on several works slow and takes time to load .

[adrianIDC]

In DETECTING takes much .
Now I 'm 10 minutes and still detecting .
It is normal late in detecting all files due to its location ?

[adrianIDC]

1 hour detecting.......it's slowly ly ly....

[Shestakov]

There is no bottleneck for file copy jobs, so "Detecting" means that VBR is trying to find it. After the job is done you will have bottleneck = N/A.
What types of files are you trying to copy and from what type of source(File system, OS...) to what destination (File system, OS...)?
Thanks.

I am trying to copy general files (pdf , office files, etc ) .
I find doubts and I made another copy of a directory of a minor GB 's in size and in the same directory as the Copy File that is slow and the result was much better and faster ( + -20Mb / s ) .


But in the other copy as you can see in the picture is 5 hours and has just copied 6GB = 12600 files


Thank you very much for your help, to see if I find a solution to this little "problem"


As they move from 500 Kb / s to 20 Mb / s is a great joy

[Shestakov]

So, what is the difference between File Copy job runs at the 1st and 2nd images, what did you change?
The processing rate difference is really significant. Thanks.
