The data stored by home users in multimedia libraries represents significant physical and emotional value. Whether it's family photographs, videos or music files, any data loss situation can be traumatic and stressful. So it would be reasonable to expect that most people would take steps to safeguard their data as much as possible from all kinds of threats, including human error, hardware failure and outside malicious attacks. As digital data volumes continue to grow, careful data management is becoming increasingly essential.
Many home users are seduced by the enticing benefits of NAS storage, which is functional, flexible and most importantly, affordable. Yet the risks of data loss from NAS, as with any other type of storage technology, should not be overlooked - perhaps the biggest danger is the fact that NAS systems often use proprietary, non-standard file systems unique to the manufacturer, so an emergency data recovery can prove costly. Couple this with other threats to data loss, including human error, hardware failure and outside malicious attacks, and it becomes clear that there is a need for consumers to take a proactive approach to safeguarding their digital files, and avoid the stress of losing personal data.
Ontrack Data Recovery, Kroll Ontrack's data recovery services, performed 69 percent more data recoveries from NAS in 2009 than in 2010 so the company is well placed to explain how to minimise the risk of suffering a data loss.
1. Access control. If the private network is used by multiple home users, you should be aware of who can access what data.
2. Create automatic backups. NAS systems offer many advantages, but not absolute data security, so it's advisable to regularly create an additional backup on other storage media for critical data, such as USBs.
3. Outsourcing. Data can be more secure if the backup is stored separately. Ensure that all outsourced data is encrypted.
4. Trust is good, control is better. Backups should always be tested. An incomplete or irretrievable backup is worth nothing.
5. Properly investing. Many home users consider employing a redundant hard drive RAID configuration (RAID 1 or 5 or 6); however this additional security (which is essential for businesses) is not necessary in a private setting. It is better and easier to invest in additional hard drives for a second backup. For home users this is a completely reasonable and easy to use form of security.
6. RAID 0 allows for faster data access, but if a disk drive fails it reduces the possibility of recovering the data. A RAID 0 configuration is only recommended for applications where performance is far more important than data protection.
7. Increase disk space cautiously. Many NAS users lose data when trying to increase disk space by adding more disk drives and/or changing the RAID configuration. However, there are NAS products available, such as the DROBO, that have the flexibility to increase disk space by allowing a disk drive to be removed and replaced with a larger one, while they are still running, and with no data loss. They also have the added benefit of managing data security automatically.
8. In case of emergency, don't panic and keep calm. Most importantly, don't try to recover the data yourself as all too often this cases further problems and can make any kind of data recovery impossible.
Most importantly, if the worst does happen and data is lost, being aware of the steps required to rectify the situation can help to restore the data as quickly and painlessly as possible, reduce the initial panic that can be felt following a disk failure and also help to prevent further mistakes from occurring.
