Batch updating is a common practice in sysadmin responsibilities, especially when managing a large number of machines. Here are some key points about batch updating:

1. Scheduled Updates:
   • Rather than updating each machine individually as updates become available, sysadmins schedule regular update sessions. This could be done monthly or at other intervals.
2. Security Updates:
   • Security updates and critical system updates are typically prioritized for batch updates. These updates address vulnerabilities and are essential for maintaining the security of the systems.
3. Service Downtime:
   • During batch updates, services on the machines may be taken offline temporarily. This allows sysadmins to apply updates and verify that everything is functioning correctly after the updates are applied.
4. Testing and Verification:
   • Before applying updates to all machines, sysadmins often test the updates on a smaller scale or in a controlled environment to ensure they won't disrupt services or cause compatibility issues.
5. Regular Maintenance:
   • Keeping systems up to date with the latest security patches is an important part of regular maintenance, helping to protect against security threats.

Batch updating helps sysadmins efficiently manage and maintain a fleet of machines while ensuring the security and stability of the IT infrastructure.
