Server failures can harm any business, and the thing is, they might be caused by such everyday events as human errors, power outages, and hardware breakdowns. With these high risks of data loss, it may seem that not all enterprises are taking the issue of backup plan's creation that seriously. It often happens due to the massive number of cloud and other digital solutions (e.g., Backup Office 365 tool) available nowadays that can significantly simplify the reserve copying process.
Nonetheless, not all backup schemes are as reliable as they should be.
For example, whether it is a proprietary backup or off-site storage, both solutions can simplify the recovery of documents, folders, and electronic correspondence, but this may not seem enough to completely restore the server. To prevent such cases and detect problems in a timely fashion, you need to check your backups regularly. Besides, backup recovery testing should be an essential part of your reserve copying strategy.
The Types of Backup Restoration Testing
In general, there are two types of backup copies testing:
• Checking the integrity of reserve copies by verification of the checksums of data blocks of the backup.
• Testing the restoration process from a backup. In a unique isolated environment (also known as "sandbox"), the system recovery process from a backup copy is simulated, and it is checked whether it will work correctly after restoration.
Potential Issues Related to Data Backup and Recovery
Checking the data backup and recovery procedure is related to the statement that all the organization's data is safe. There is nothing easier than adding a new server and forgetting to include it in the backup process. Media may have hidden defects or corrupted data, which makes it impossible to restore them.
Experience of individual businesses says that organizations often skimp on testing backups. It could be due to a lack of awareness about possible problems during the recovery phase and economic factors since the full process of checking the system restoration from a backup, if performed manually, is a very time-consuming procedure. This situation may have serious repercussions because, in the event of a technical breakdown, critical data may not be restored at the set time, or, what's worse, it may be partially or entirely lost.
The Guide on Checking Your Data Backup Recovery
There are several ways to test the backup and restoration procedure, ranging from reviewing a list of activities to a full-scale simulation. All-out modeling of force majeure is the most proper testing, although it is the most challenging option to implement since everything must be done without interfering with business processes.
The backup testing process should verify that the reserve copying is being performed on all crucial systems and servers or that no files have been accidentally or intentionally excluded from archiving.
Thus, our short and comprehensive guide on how to test the accuracy and quality of backup recovery consists of the next steps:
1. View the list of all servers and all critical file systems not to miss important points.
The process of checking information restoration should allow you to be sure that the data for the required period is in the right place and available for reading. During the test period, you need to record the time interval for performing all stages. It is also obligatory to record all issues that occur during recovery actions or restarting programs. These issues should be taken into account next time to determine how to speed up the procedure and improve it until the moment when everything happens for real.
2. Consider the option of fulfilling fallback recovery.
Emergency recovery requires more than just the ability to back up and restore valuable documents. You should be able to quickly transfer workflow processes to another data center for processing in the case of any unanticipated occurrences and promptly locate your files and applications on a new server. Testing the process of data backup and restoration represents a vital point in ensuring your company's security in the unforeseen event.
3. Ponder on the most suitable backup solution for your company.
Unfortunately, you won't find any ready-made backup solutions able to meet the demands of every enterprise. Nevertheless, when seeking the best option for your business, consider several essential aspects. The chosen solution should archive all workflow processes and, if a server experiences complete failure, resume the company's work within a short time. Opt for an easy-to-expand, cross-platform product that allows you to create backup copies to both physical media and the cloud storage, and offer two corresponding data recovery variants.
Take your backup restoration seriously, as it is no less important than the proper performance of reserve copying itself.
