17.3. Backup Problems

Problem

On the backup Node, some of the multiple scheduled backup tasks fail with the “unauthorized request” error.

Solution

This may be caused by the VA Agent’s limit for the amount of simultaneous sessions on the backup Node. Set to 20 by default, the limit may be too low for multiple backup tasks. Try raising the VA Agent’s limit for the amount of simultaneous sessions on the backup Node. To do it, add the <user_session_limit> parameter to the <sessionm> section of the /var/opt/pva/agent/etc/vzagent.conf file. For example:

<sessionm>
<configuration>
<user_session_limit>200</user_session_limit>
...
</configuration>
</sessionm>

Propagate this adjustment to every backup Node involved.
