I start vzbackup from the remote node and get an error:
ssh: connect to host domain.host.com port 22: Connection timed out 2013-09-11T15:48:27-0600 vzbackup(901073): Error: unable to obtain vzbackup version on domain.host.com
However, when I run vzbackup locally - backup created successfully.
The reason is incorrect work of the dns-server, so hostname cannot be resolved to ip.
You need to reconfigure dns-server.
As a workaround you can perform the following steps:
Setup rsa-keys on the both Source and Backup Nodes;
Add this keys to the
/root/.ssh/authorized_keyson the both Nodes;
/etc/hostson the both Nodes: add on the Source Node
<ip_Backup_Node> <hostname_Backup_Node>and on the Backup Node -
<ip_Source_Node> <hostname_ Source_Node>
