kopano-backup gsoap connect error

Hi all,

while backing up a multi tenant installation i get the following error but an RC 0 at the end

20171211-000001:  Backing up company people
[error  ] gsoap connect: ()
20171211-000016:   RC: 0

I am using the following comamnd line

/sbin/kopano-backup --company=people --skip-junk --skip-deleted --log-level=DEBUG --output-dir=/var/opt/vackup/kopano-bricklevel

I wonder, if it has something to do with

2017-12-12 08:11:14,696 - backup0 - DEBUG - backing up folder: "soenke" "Posteingang"
2017-12-12 08:11:14,778 - backup0 - WARNING - cannot serialize rule for unknown store/folder


2017-12-12 08:10:19,844 - backup - WARNING - no data found for attachment of item with entryid 0000000034A4D3E85B5B43B58942A972F8710A6E0100000005000000028518FBD44C4F458165573EC68EF84100000000

The second error i possible caused by my clamav virus scanner who has delete a malicous file in the filesystem.

BTW How can i detemine the corresponding object in Kopano to delete it there too? Maybe in the first place during virus scan by using kopano-python?

Kind regards,

Hi, I see the same error “[error ] gsoap connect: ()” but only with a single company.
Kopano on SLES 12 SP3.
Any ideas what this error means?

Did you find a cause?

sorry I did not find a solution for this issue.


But It is not recommended to just delete items in the attachment store, at least put a stub file with the same name back.

If you want to scan your mailboxes please see https://github.com/bkram/kopano-scan-attachments which can do this in the correct way through python-kopano and with clamav.

I modified the provided db-remove-orphaned-attachments script to find attachments missing on disk, not tested much YMMV, I placed it here https://gist.github.com/bkram/db1944a37cd211469163f23e4df5917f
This way you can just touch the missing file and get rid if the search error.

Kind regards,
