A server maintenance checklist is a list of tasks used to ensure a server is running efficiently and securely. It typically includes tasks such as updating the server operating system, creating backups, monitoring disk usage, and checking system logs. Additionally, tasks such as patching security vulnerabilities, testing server functionality, and performing regular system health checks may be included in the checklist. It is important that these tasks are completed regularly to avoid outages and security issues. The server maintenance checklist should be tailored to the specific needs of the server and should be updated as new technologies and processes are adopted.
