Issue Backup issues after updating to 18.0.51 - Unable to validate the remote backup

[hamstercodes]

Server operating system version

Ubuntu 20.04.6 LTS

Plesk version and microupdate number

18.0.51

After updating to 18.0.51 I started getting random warnings from my scheduled backup tasks.
This only happens to a couple of my customers and even for them a couple times a week (not every day).
I get a warning saying "Unable to validate the remote backup. It may not be restored. Error: Unable to extract dump header"

I'm using OneDrive as my remote location. I tried unchecking "Validate backups via checksum" but that didn't stop the warnings.
I'm using Backup to Cloud Pro extension.

Backups were not modified on the past version iterations. The error message rather points to long (too long) response times of the backup target that are causing timeouts.

Maybe the error message could be closer to what actually happens? Now it seems to suggest there is something wrong with the file itself.

I have exactly the same issue, but just after 18.0.52 update.

I'm still having this issue. Haven't really had time to debug more. Tried splitting the backups into smaller files as well but no luck

...That's exactly what I am trying right now. To bad.
I'm also trying Google Drive, I'll post results here

Thanks. When I used Google Drive before it worked like a charm. Maybe OneDrive is the issue?

I've been having the same issue for at least three weeks. I'm backing up to a Google Cloud Storage bucket (S3-compatible), so I don't think that's the problem.

I had something like that some Updates ago. It caused issues when bachup. I identified two issues, one was trouble with 2 htaccess files. I removed them, waited some time and got up one which works (there must have been a fault somewhere in the files). The second was a problem that 3 IP's where not connected as they sould. I disconnected the IP, connected the IP's at the server via ssh again, reread in plesk and reconnect them. Last issue at one domain I wasn't able to solve, so I deleated the domain out of plesk. After that next backup went through as normal.
