Summary: This blog acquaints you with RAID servers, causes for their failure, raid data loss prevention tips, as well as RAID data recovery service in case data is lost despite taking precautionary measures.
‘Redundant Array of Independent Disks’, commonly and popularly known as RAID servers. Raid Server are a data storage systems used in businesses and enterprises and used to store a significant amount of data in more than one hard drive. Depending on the number of hard drives and redundancy provided by the technology used, further categorisation of the RAID servers into levels such as RAID 0, 1, 2, 3, 4, 5, etc. The purpose is to have multiple and redundant drives are to avoid data loss if any drive fails. If one drive fails, then we can access data from the rest. This results in increased storage capacity, data availability, and reliability, all these contributing to improved performance.
Well! There can be several approaches to redundancy such as power, storage, network, server, data backup and replication, load balancing, disaster recovery, site redundancy, etc. Nonetheless, RAID is all about withstanding drive failure without losing access to data. This is because if a drive without RAID fails. You have lost your data forever except in cases wherein you have a backup created in external drives. However, RAID servers can fail which may lead to data loss. Know the possible RAID Data Loss Causes and Prevention Tips in the section below:
Causes for RAID Failure & Data Loss Situations
The several reasons for failed RAID servers and data loss causes are as follows:
- Virus Attack – Although all the RAID servers are protected with a strong and powerful antivirus program. (But sometimes the attack by malicious code is so intense and may cause RAID failure and hence loss of data.)
- Mishandling by Users – This is one of the most common causes of data loss. For instance, data deletion or formatting, partition deletion or formatting, partition overwriting issue, incorrect reinstalling, accidental reconfiguration of RAID partition, etc.
- Power Surge or Outage – Electrical power issues is yet another cause for failed RAID servers and data loss. Here, in this case, specific utilities and advanced techniques are necessary to restore the lost information.
- Natural Disasters – Water and fire from natural disasters such as flood, the explosion of lava or any other reason leave the RAID systems useless. The reason being, these can affect and damage hardware, software, or both the components. Rebuilding them means to reconstruct the file systems with specific techniques and solutions, to restore data from the failed RAID systems.
- Other Causes – Failed RAID Controller, damage in RAID Strip, failure of RAID array, loss of RAID system registry or configuration settings, error while rebuilding RAID or issue in volume reconstruction, wrong replacement of hard drive element to a working RAID, multiple drive failure, application upgrade etc. are the other causes of RAID failure and loss of the stored data.
RAID Data Loss Prevention Tips
As you are now aware of data loss reasons in RAID servers, you should know RAID data loss prevention tips.
- Keep a powerful antivirus which updates to the latest release
- Avoid mishandling such as do not delete or format drive data/drive partitions
- And do not overwrite, do not install in the wrong manner, do not reconfigure RAID partition and others.
- Check that there is no power outage and that your RAID servers have uninterrupted power supply.
- Protect your RAID systems from natural disasters, fire, water, etc.
- You should label the drives in the array on their positions.
- Do not try to repair damaged drive on an inaccessible partition with a repair utility.
- Before rebuilding RAID, always ensure that the drives are in a healthy state.
- Immediately stop the RAID rebuilding process, if multiple drives have failed simultaneously.
- Do not run any defragmented utility until you check the health of the individual drives
- In case if any of the drives in RAID 5 or above is in a corrupt state, assure that the new drive is filled with zeroes has more or equal sectors in the drive that is damaged, while you replace it with a new one.
Note – Despite RAID data loss prevention steps, RAID servers can become corrupt or damaged to the extent that professional RAID recovery solutions become essential.
