How do you maintain and support operating systems?

Well, - Keep updating as per new release, NOTE 1- read release note before upgrading. NOTE 2 - Have a backup before attempting an upgrade - Maintain CVEs (Security updates)

Para fazer um backup de forma correta é importante conhecer os passos de execu??o e recupera??o do backup que devem ser de fácil compreens?o. Backup de máquinas virtuais como (VmWare) e AWS como exemplo, podem ser feitos de forma completa abrangendo todo o sistema operacional e n?o somente os dados presentes no sistema. Backups de OS em computadores domésticos, s?o demorados porque dependem de recursos limitados a velocidade do hardware disponível, sendo recomendado somente o backup dos arquivos e a formata??o do dispositivo após o término o backup.

A realiza??o de backups regulares é crucial para garantir a integridade dos dados em caso de falhas do sistema ou desastres. Eu costumo configurar solu??es automatizadas de backup, como o Windows Server Backup ou ferramentas baseadas em nuvem, para realizar backups incrementais diários e backups completos semanais. Além disso, testo periodicamente os procedimentos de restaura??o para assegurar que os backups s?o confiáveis.]

Backup is always needed. Make sure you take backups from all important applications and infrastructures datasets. Always have a backout plan while implementing change orders, it’s really important to have an easy backout plan in case problems happens. Spend more time planning the changes and use more of automation. Make sure to set your file systems the correct group, owner and correct authority for read, write and execute. Guarantee that you have security with data in transit and in rest. After the changes done make sure you have a solid validation plan to guarantee everything is working fine after the changes are done. Keep eyes on the memory and CPU consumption while executing workloads to guarantee the best performance.

Regular data backups are essential for maintaining operating systems. Data loss can occur due to various reasons like hardware issues, malware, or human error. Options include external drives, cloud storage, or network devices. Periodically test your backups to ensure they work. This practice safeguards your data for emergencies.

I totally agree with this for the home users, but for enterprises things are working differently, cause servers cannot be restarted just like that, and update need to be tested before deploying it to the servers, also for the clients workstations, updates are get tested first to ensure compatibility then it get pushed to the clients off working hours.

If we are using server we need to deploy and are concerned about the following issues to avoid clients' service: Restarting a server can disrupt client services. To minimize downtime, schedule restarts during low-activity times, use load balancing, and implement graceful shutdown procedures. Communication with clients about maintenance is key, and testing updates in a staging environment helps avoid issues.

Keeping it current with the latest drivers and patches is a huge step in setting you up for success. This will also help in troubleshooting the OS if there are issues.

Manter o sistema operacional atualizado com as últimas corre??es e patches é fundamental para a seguran?a e estabilidade. Utilizo ferramentas como o WSUS (Windows Server Update Services) ou configura??o automática via Group Policy para gerenciar atualiza??es em ambientes Windows. Em sistemas Linux, scripts cron podem ser usados para agendar atualiza??es automáticas usando apt-get ou yum.

I agree with your opinion and my perspective is Optimizing your OS is vital for enhanced performance. Remove unnecessary files, defragment the hard drive, clean the registry, disable unnecessary startup programs, adjust power settings, and use disk optimization tools for a faster, more efficient system.

A otimiza??o envolve ajustes no desempenho do sistema através da limpeza regular do disco, desfragmenta??o (quando aplicável), revis?o das configura??es de inicializa??o e remo??o de softwares desnecessários. Ferramentas integradas ao SO ou terceiras podem auxiliar nesse processo.

Protect your OS from malware and threats: Use updated security software. Regularly scan for malware. Be cautious with links and downloads. Employ a firewall. Use strong passwords and encryption. Consider a VPN for privacy.

Troubleshooting your OS is essential for problem-solving. To address issues and prevent their recurrence: 1. Restart Your Device: Clear memory and cache by restarting. 2. Error Messages: Examine error messages and codes for insights. 3. Built-in Tools: Use OS-provided troubleshooter and diagnostic tools. 4. Safe Mode: Boot in safe mode to identify and fix Issues. 5. System Restore: Revert to a previous OS state using system restore or backups. 6. Online Resources: Seek solutions in online forums or expert advice. These steps empower you to diagnose and resolve OS problems effectively.

Troubleshooting your operating system is indeed an essential step in maintaining and supporting it. Restarting the device, checking error messages, using built-in troubleshooters, and accessing safe mode are all effective ways to identify and resolve issues. It's also helpful to seek assistance from online resources and forums to find solutions from other users and experts. If you're encountering specific issues with your OS, feel free to share more details so I can provide more targeted advice.

Need to some root cause analysis to see what the issue is. Could it be that the update broke something? Verification of being current will help stop most issues from happening. Although nothing is 100%, being current will help.

Quando surgem problemas técnicos nos sistemas que administro, utilizo uma metodologia sistemática baseada na identifica??o dos sintomas apresentados pelo usuário final até chegar à raiz técnica da quest?o utilizando logs eventos/sistema além das próprias mensagens erro exibidas pelos programas afetados.

Mantenho-me constantemente informado sobre novidades relacionadas aos sistemas que gerencio através da participa??o em fóruns especializados online como TechNet/MSDN Microsoft Stack Overflow comunidade Linux entre outros além cursos certifica??es periódicos mantendo assim meu conhecimento sempre fresco relevante frente às demandas tecnológicas atuais.]
