Upgrade Backup Agent on CentOS, RHE and Fedora

Notice
For Server Backup 5.2.x and later, you must upgrade the components in the following order or your backups may fail:

Data Center Console (if applicable)
Backup Manager
Backup Agent

Notice for Version 5.x

With the product name change from "CDP" to "Server Backup," the RPM package name changed. This means that after you upgrade from a pre-5.0 agent, you will need to manually start the new agent by executing the following command:
service cdp-agent start
We recommend that you update the kernel module by running:
serverbackup-setup --get-module

To upgrade the Backup Agent from 5.0.2 or 5.2 on Linux, follow the instructions below.

1. Perform the following manual steps before the upgrade:

Stop the Backup Agent by executing the following command:

 service cdp-agent stop 

or

 /etc/init.d/cdp-agent stop 

Verify that there are no running or defunct cdp-2-6 processes by running:

 ps ax | egrep –i c[d]p
 

2. Proceed with the upgrade:

 yum update  

Confirm your request by entering "y":

Or:

 yum install serverbackup-enterprise-agent 

Enter "y" to confirm the command.

3. Start the new Server Backup Agent:

 service cdp-agent start 

To verify the most recent version of the Agent is running, run the following command:

 egrep "Agent Version|Starting" /usr/sbin/r1soft/log/cdp.log | tail -n2 

To upgrade Linux Backup Agent to version 5.x, perform the following steps.

1. Execute the following command:

 serverbackup-setup --get-module 

The upgrade process can take some time.

2. Then manually restart the new Backup Agent by executing the following command:

 service cdp-agent restart 

A Full Block Scan will be initiated after an agent upgrade due to a restart of the agent service/daemon. This ensures replicas are consistent even after a server crash or reboot.

3. After the upgrade is complete, execute the following command to make sure that the latest version is installed:

 rpm -qa | grep serverbackup
