6 Ways To Improve Raid Recovery Efficiency and Speed Up the Process

Raid recovery is a process where you need to recover data from a failing storage device. Whether it’s a drive that has failed or your RAID controller has a software bug, you need to recover data from your RAID array. As a sysadmin, you’re aware that recovering from a failed RAID array is a time-consuming process.

You also know that you need to speed it up if you have a busy data center with many servers. You can do this by automating the recovery process. Read on to know how to improve recovery efficiency and speed up the process.

Plan Ahead

It’s important to plan ahead for raid data recovery services. It’s best to have a backup strategy, in case you don’t have any extra drives laying around. You should also verify with your storage vendor if they offer a hot spare.

Disable Unused Devices

You can improve your recovery efficiency by disabling unused devices. You’re probably running a RAID array with a few disks that are mostly full. So, you don’t need to use them at all. You should disable these unused devices to speed up the recovery process and prevent other drives from crashing due to overloading on I/O requests.

To find out which drives are unused, you’ll need to use software like smartctl, which is able to detect temperature, power usage, and disk health status. This information is then displayed on the device’s controller interface.

Use Differential Indexing

Differential indexing is the process of using the contents of a single file to reconstruct the full contents of a previously deleted file. It’s a useful tool when you want to speed up recovery on RAID arrays with lots of different files. You need to use differential indexing when you run an initial backup before data is deleted and then you want to recover it later.

Differential indexing allows you to recover your data faster because it only indexes what has changed since the last time it was backed up, rather than having to go through all your files and find out which ones have been modified.

Install Software Trials

It’s important to test your software before you deploy it. The best way to do this is by installing trial versions of software on each of your servers. For example, if you have a server set to run Windows Server 2008, install a trial version of the operating system first.

Then when the trial period has expired, deploy the production software with the same settings for that server. This lets you confirm that your recovery plan will work as expected before you spend time and money deploying it.

Use Different Scenario Tests

It’s important to test different scenarios in order to find the fastest recovery process. You can do this by using scenarios that simulate different failure situations, such as a drive failure. For example, if you want to recover data from a RAID 1 array, you should test with and without the failed drive, as well as with and without the RAID controller failing.

A scenario test is also useful if you want to speed up your manual recovery process. You can have an admin manually recover data from a failed drive or RAID controller and compare it to automating the process. These tests will show which method is faster for recovering data.

Change Settings and Common Tasks

When recovering from a failed RAID array, you need to change settings and perform common tasks. This can include changing RAID mode settings, adding or removing drives, or recovering data from the failing drive. By automating these tasks, you can speed up the process.

For example, if you have a RAID 5 array with four disks, installing the fifth disk will simply require one step on your system. Additionally, configuring the RAID 5 array for write performance is only one task that needs to be done before recovery.

Conclusion

Raid recovery is one of the most important processes of the day and can have a huge impact on the time it takes for your data to be restored. These 6 ways to improve raid recovery efficiency and speed up the process can make all the difference.
