Kopano-backup trough socket


I’ve installed Kopano 8.6.7 and I like to backup an old Zarafa-Server 7.1.4 with the command kopano-backup -s … to migrate to the new kopano with ucs.
Some time ago, I tried this with - I think - Kopano 8.2, and it works.

Today, I tried to migrate, but I got this message:
2018-09-19 00:40:58,217 - backup - WARNING - could not connect to server at ‘192.168.X.252:236’, retrying in 5 sec

I used this command:

kopano-backup -s 192.168.X.252:236 -U administrator -P ‚XXXXXXX‘

Did Kopano change the kopano-backup routine or what is the failure?



Hi @rs_1981,

@rs_1981 said in Kopano-backup trough socket:

kopano-backup -s 192.168.X.252:236 -U administrator -P ‚XXXXXXX‘

You are missing ‘http://’ in front of the socket

Ah, okay, thanks. But then I get this error:

Is it the same like this:


No, since the traceback is completely different.

In any case I was able to reproduce the issue, will check with a developer tomorrow about a possible solution. The workaround is to not backup all users at once, but specify the user to be backed up (-u username)


that information helps me very much.
Then I use a shell script for backup.

Perhaps, you can find a solution to backup all users.
