1- Acknowledge the issue promptly and transparently. 2- Isolate the affected system to prevent further damage. 3- Analyze logs and error messages to identify the root cause. 4- Implement a temporary workaround if possible. 5- Escalate the issue to appropriate personnel if necessary. 6- Communicate updates regularly to stakeholders. 7- Document the incident for future reference and improvement.

As atualizações de software são inevitáveis e essenciais para manter sistemas seguros e eficientes. No entanto, é crucial gerenciar bem o processo para minimizar o impacto no negócio. Algumas das práticas para restaurar as operações: Planejamento antecipado: Realizar simulações e criar planos de contingência antes da atualização. Backup completo: Garantir que todos os dados estejam salvos para evitar perdas críticas. Comunicação clara: Informar a equipe e os usuários sobre o cronograma e possíveis impactos. Monitoramento em tempo real: Acompanhar o desempenho durante e após a atualização para detectar e resolver problemas rapidamente.

Uma vez em uma GMUD programada, tive um problema desses, o que me ajudou a minimizar o impacto foi o excelente planejamento e documentação da GMUD realizada pelo meu time técnico. Ao identificar o problema, conseguimos isolar o ativo afetado e calcular que o tempo de retorno seria muito extenso. Então optamos por aplicar o plano de rollback e deixamos o sistema online em 60 minutos, durante a semana analisamos com calma o ativo afetado, replanejamos a GMUD e executamos com sucesso 15 dias após a primeira tentativa. O segredo é gastar um tempo no planejamento e conhecer os ativos alvos da atualização e qual o impacto se der problemas.

Before any update, perform a full backup, if possible. If not, at least, a differential backup could work. Now, there are several “systems” that could be affected, like email servers, DB, AD, Applications, you name it and every one of them have different recovery approaches. I find useful to perform recovery drills at least twice a year to hope for the best but prepare for the worst. A communication plan before, during and after the updates and recovery, will keep people aware of the situation and credibility will develop.

1. Isolate the failed system 2. Activate disaster recovery plan 3.Rollback the update or apply a hotfix 4.Utilize redundant systems and failover mechanisms 5. Keep stakeholders informed about the situation 6. Conduct root cause analysis 7. Implement preventive measures

When a system goes down due to a software update, it is essential to act quickly to restore operations and minimize downtime. First, verify that the update completed successfully and check for any error messages that may assist in troubleshooting. If issues persist, roll back to a previous stable version of the software to ensure minimal disruption. Communicate transparently with stakeholders about the situation and expected resolution time to maintain trust. Additionally, having a predefined recovery plan and prioritizing critical tasks can significantly enhance your ability to manage unexpected system downtime effectively.

1. Execute the backout plan 2. Have a backout plan 3. In some cases, there is no backout option due to the nature of the update (Database schema upgrades, etc.). In that case there is no other way than forward: a. Pull in manufacturer support ASAP b. Triage to decide if a workaround or fix is feasible: 1. Continue work to restore service 2. Or- Rebuild the system from a known good configuration using as-built specifications. This will require having a good as-built configuration and documentation to rebuild the service. In the worst-case scenario, it is critical to have the ability to rebuild a service from the ground up, then restore data to restore service.

Quickly switch to a pre-tested backup system to maintain essential operations while diagnosing the root cause through log review. If the problem is caused by the recent update, perform a rollback to restore stability or apply a hotfix for isolated problems. Inform affected users about the issue, recovery timeline, and available workarounds. After recovery, conduct a thorough analysis to identify the root cause. This approach ensures minimized downtime and rapid system restoration through swift action, backups, and clear communication.

Operations should never be affected. Schedule updates to run after hours and off peak. If you have to run an urgent update during operating hours, which usually never recommended, ensure have a recent backup of live ready to deploy within minutes in anticipation of failures There is usually a whole strategy and mitigation plan for updates I don’t see this really being an issue in this era.

We can roll back the newly installed update, which should bring the server back online. However, sometimes things are not so straightforward. Certain software updates, once installed, may prevent the operating system from booting. In such scenarios, additional time may be needed for troubleshooting, which results in downtime for the company. To address these types of issues, it is essential to deploy BCDR solutions such as Veeam or Arcserve Backup. In case the production server goes down due to issues like system updates, hardware failure, or a ransomware attack, the entire production server can be restored or recovered, or it can be run as an instance.
