Good night!!.

Welcome to the forum @Gerllys_Speroto_Calv

Is this the first backup or did something break? What Duplicati version are you running?

About → Show log → Live → Retry will probably show some retries before a final error.
Unfortunately, time is in minutes (unlike with log-file), but maybe you can guess timings.

On screen 5 Options, is Remote volume size 50 MB? What’s Internet upload speed?

What operating system is this?

3

Hey!.
Yes, it is the first backup.
The remote volume size 50 MB. The internet has an upload speed of 100MBpS.
Windows Server 2008 R2
Duplicatti 2.0.6.1_beta_2021-05-03

Hi!
Same issue here. Did you manage to solve it somehow?

5

The problem was solved by upgrading from windows 2008 to windows 2012 on the server.

6

Thanks for the info! But we have to stay on 2008 r2 here for now :frowning:

7

Is it possible this is a TLS 1.2 issue? From what I recall, 2008 R2 doesn’t have TLS 1.2 enabled by default. It requires some patches and then some registry changes (if I’m remembering correctly).

I could be way off base though. It may have nothing to do with this issue.

8

It seems it is not TLS issue. For tests I have tried to backup a small folder with just several txt files in it. And it was successful. But when I started to backup some folders with real data (10 gigs and more) I could see in Duplicati that upload speed slowly goes down from something like 10MB/sec to near zero. Maybe some onedrive’s throttling for some reason.

9

Sorry, I was referring to the original issue where the OP reported the “An existing connection was forcibly closed by the remote host” error, which was resolved by upgrading from Server 2008 to Server 2012. I was wondering if that in particular was possibly a TLS 1.2 issue.

The speed issue is definitely different…

10

Actually after some time of backup process I get the same error: “An existing connection was forcibly closed by the remote host” too.

11

Does that mean sometimes backup errors, or backup always errors after some time?

If you have an occasional error, look at the backup logs for the ones that finished, and
Complete log may show that you’ve had some connection glitches saved by retries:

“RetryAttempts” in “BackendStatistics” is the total for that run. Too many at once error.
number-of-retries and retry-delay can be raised if you tend to get connection failures…

12

The backup always fails after several upload attempts. I have tried rclone and it uploads files to the same onedrive account flawlessly and at a much higher speed! So maybe Duplicati really has some problems with 2008 r2.

13

Rclone gets its TLS support straight from the go standard library but Duplicati gets it from Windows.

Persuading Windows 7 to do the current crypto was a challenge maybe similar to Server 2008 R2’s.

OneDrive is sort of a brand (not a technology). Which one do you have? Some don’t allow older TLS.

Disabling TLS 1.0 and 1.1 for Microsoft 365

Requiring TLS 1.2 is growing common, e.g. can your Internet Explorer open https://openbsd.org?
