Cpremote use the backup daemon process to update backup as a cron service under the root user .
0 1 * * * /usr/local/cpanel/scripts/cpremote/cpremotebg > /dev/null 2>&1
You can change the cron time as you wish.
The openssh service by default only accept 10 concurrent connection from an IP . So if you are using parallel backup option , sometimes the ssh/sftp connection will be slow. This is not an issue with cpremote . To increase the speed , you need to configure the remote ssh storage pool server settings as follows,
Edit /etc/ssh/sshd_config and add the following lines
MaxSessions 100 UseDNS no
Now restart the following services
systemctl restart sshd systemctl restart systemd-logind
You can monitor the ssh log files in /var/log/auth.log or /var/log/secure to see the connection traffic.
