Data loss for businesses can be a nightmare especially when you don't have a recent backup system. Critical data that is lost can even ruin your business causing loss of client contacts, financial information and other business data. Apart from being proactive about data backup, businesses should also be prepared for data recovery plans in case of a disaster.
What are some of the frequent causes of data loss?
Power failure is probably the single most of data corruption and loss causing damage to both hardware and data. The most common scenario this happens is when a power failure occurs when the physical storage media such as a DVD or USB memory stick or Hard Drive is being written to.
Hardware failure due to frequent use or many years of use can cause irrecoverable data loss. A hard drive failure means that critical data is lost. Bad Sectors need to be immediately marked using a tool such as ScanDisk or the disk should be replaced in order to prevent further damage.
Software that write to disks such as partitioning software, disk formatting software can cause a disk to become corrupt, if stopped in the middle of an operation or if the very disk software itself is buggy.
Human error is also another common cause of data loss. For example a file or folder could be deleted by mistake because of a wrong keystroke.
•Viruses and Malware
Viruses and malware infecting the PC can also delete data or overwrite existing data with junk or malicious code.
How to recover lost data?
Depending on the type of data loss, there are many solutions available to recover lost data. Some of these are software based solutions while some require the help of an expert to analyze the problem and use semi-automated recovery procedures. A data recovery company will usually set expectations beforehand that data recovery is not a guaranteed option.
When a data loss occurs, its good to plug out the disk or drive so that further data loss doesn't occur.
