Network speed limit to 200 Mbits/s for backup ?

Post by simssototo » Wed Aug 10, 2016 10:25 am

Hi Support,

I'am using Backup4all Professional V.6.1 build 188 on Windows 10, and it's a great product, but I experience a problem when I backup to a NAS.

I noticed that all my backups to a NAS are quite slow, and never exceded 200 Mbits/s. My network is full Gigabit.

I did some tests to isolate the problem.

1/
I transfer a 4,5 GB file using Windows Explorer to the NAS and the transfer speed is about 950 Mbits/s (110 MB/s). So the network speed and the disks array speed in the NAS can't be the source of the problem.

2/
I create a new backup job (full backup) for this only file, without compression or encryption to try to maximize speed.
The result are in the following screenshots.

Task Manager when backuping to NAS ("Envoyer" means upload) : http://img4.hostingpics.net/pics/382424Capture.png

Task Manager when testing backup ("Recevoir" means download : http://img4.hostingpics.net/pics/286236Capture3.png

The upload speed never exceed 200 Mbits/s. Moreover, when Backup4all test the file once copied, the network read speed is a slitly over 200 Mbits/s.

3/
To verify that the source hard drive was not the problem, I repeat the same procedure with a RamDisk indead of my data hard drive.
The result is the same than the test 2/.


I contact you because I can't go any further to resolve this issue.
Can I send the logs of those backups directly by email (support[at]backup4all[dot]com), or need I a ticket number ?

Best regards
Jonathan
