Best Practices for Disaster Recovery on Oracle Cloud

Any business or company that operates online knows the problems that can arise at any given time or moment. The mere mention of a computer issue can scare the average user and cause chaos and mayhem. Therefore, there needs to be a set of actions to rectify the situation as soon as possible. 

A disaster recovery on Oracle Cloud plan must be put in place. Most DR plans will prepare your company for unexpected problems or disasters. They can also provide continuity for your work and generally guarantee safety as well. It should comprehensively take into account your infrastructure and identify the potential vulnerabilities of your assets.

What do you do, then, if a disaster in Oracle Cloud comes up? You have to deal with it head-on. There’s no other choice. To help you get through this difficult time, here are some steps to guide you and get you back to work as quickly as possible:

Isolate The Problem

As soon as a cloud disaster occurs, you need to take immediate action. The first step is to isolate the root of the problem. Is the server’s memory running slower than normal? Are there any other issues that could be affecting your server such as an Active X vulnerability? Identifying the cause of your problems will help you avoid having a long breakdown.

If you need to repair your cloud system, then you’ll need to deploy a full-blown recovery process. This is not easy and, many times, it’ll require a full backup of your system. You may also need to recover some lost data, such as emails. This can all be done by you. Just follow your usual recovery steps such as disk defragmenting and file extraction.

Have Additional Backup

You should also have a backup in place for your application servers, as well as for your Oracle Cloud. There may come a time when you want to recover your Oracle Cloud to fix a minor issue that caused it to break down, but you’re not able to. Make sure you have a backup in place for those particular issues. 

Assess Method of Recovery

You need to decide how you’re going to recover your database and what recovery method you’ll use. You can either use Oracle Backup Manager (OBM) to restore your database to a previous state or you can roll back to a previous database or user. This will be a long process as it’ll involve taking backups of all the database information in place. You may even need to store the database recovery log in order to retrieve this data later on.

Examine and Review

You should also take note of how your Oracle Cloud is performing at that time. If it’s not responding, or if your users can’t connect to it, then it’s not performing to its maximum capabilities. This will help you find the cause and ensure that the next time you use the Oracle Cloud, the same problem does not appear.

If you have any applications that are running in the Cloud, they’ll need to be brought back up as well. If you can’t access them, then the server may be down for the day and you may have to wait until it has been brought up. If you don’t have access to your application servers, it’ll be much harder to restore them.

Once you’ve made it through the disaster in Oracle, then the recovery is easy as all you need to do is go back to your Oracle Cloud and bring it back online. You’ll still need to recover your data from the backups you took, however, the process will be slower than when you have restored the data with a restore function. If you haven’t taken backups before the disaster occurred, then you may have to back up the data manually.

Don’t forget that you can restore any applications that weren’t backed up before. You can also recover those files using the restore function on your application server. When you restore the data from the backup of the application servers, it’s also important that you create a recovery log to make sure you do not repeat the same errors in the future. After you create this log, you can manage this information to review the details regarding such processes.  

This log can then be used to find the cause of the disaster and you can recover the data from backups in the future. It’ll also help you monitor your application servers to ensure that you don’t have to face this type of problem again.

Conclusion

The recovery steps above should help you recover your database and bring it back online. For more information, check out online resources for more complete instructions and diagrams on creating backups, archiving, and designing a disaster recovery plan.
