I get some ERRORS after upgrading to ISPConfig 3.2

I get some ERRORS like
Backup of web files for domain ..... failed using path /var/www/clients/client2/web6 failed.
I have approx. 25 web pages but I get errors on four web pages only (sql backups work normally). Other pages creates backup files and sql as before update.
How to find reason, what is wrong?

 

It is not a multiserver setup. A you can see from attached image that backup worked normally before upgrade ispconfig into last 3.2 version. I found only cron.log entries that are the same as error inside control panel (see image)
Where could I find correct log error?

 

See attached file please..I removed domain names...

 

Please make sure that you select a supported backup method (compression type) and that you have that program installed, too.

 

Of course I have selected supported backup method. I have the same settings for all web sites but I got this error since I have upgraded into 3.2 version but as I said there is a problem on four pages only. Everything worked fine before upgrade. Without any error.
See settings at attached image.

 

Strange enough.

Code:

zip warning: No such device or address
20.10.2020-12:04 - ERROR - Backup of web files for domain ........... failed using path /var/www/clients/client18/web57 failed.

Readind the warning it seems that zip cannot read the web. May it be that it happens on webs with SSH user (chrooted) enabled?

 

No, there is no SSH user (chrooted) enabled.

 

Hm, could you deep-check the affected websites if there are any files or folders with special types (device, proc, bind mount etc.) just to try to find the reason why zip is warning about it.

 

I also got the same error after updating ispconfig to version 3.2.
Like johnymas' #3 problem, the ISPConfig log shows that a backup error has occurred, and only the database is backed up in the Backup tab of the domain menu.

Not all sites are like that, and some sites have problems every day.
Some of the sites where the problem occurs are those where shell users are created using jailkit.
Also, some of the sites with problems do not even have a shell user.

There are a total of about 100 sites on the server, but only 9 sites have backup issues.
These 9 sites have daily backup errors in the log, and backups are not in progress.
The 9 sites do not have common settings.

 

Should I show all the tabs in the domain menu?
What additional settings need to be shared?

 

Some domain and database file names have been removed.

 

Another domain on the same server where the same problem occurs.
The domain above is a domain created with an account with administrative privileges, and the domain in this post is a domain created with general user privileges.

Both cause the same backup problem.

 

Today I got even more errors. I think there must be a bug??

 

Site creation times vary.
However, most sites are over a year.
No site was created after updating ispconfig to version 3.2.

 

Three of the webs were created more than 5 years ago, one of them was created almost a year ago...
Same as clamp2x said, no site was created after updating to version 3.2.
