Secure data storage involves keeping a backup of data offsite, encrypting data, and proper organization. Multi-device backup can be done on home or office networks, while cloud-based storage sites offer remote access. Data encryption and separating the operating system from user data also improve security.
Secure data storage refers to ensuring the survival of personal or business computer data in the event of a hardware or software failure. One of the best practices for securely storing data is to keep a copy of your data offsite to use as a backup. This involves moving the data to a remote storage device or to an online storage site, such as cloud-based storage services. Encrypting data on both your data and backup to prevent unauthorized access is another way to ensure secure data storage. Proper data organization and management can also significantly reduce the risk of data being compromised.
The most common type of secure data storage, multi-device data backup, can be done on any home or office network. The user can save copies of important files on various drives, including separate hard drives and portable Universal Serial Bus (USB) hard drives. Data can be transferred to add-on units via direct connection, wireless communication devices, and recordable media such as digital video discs (DVDs). Multiple backups allow the user to access data even if its main storage is compromised by malware or physical damage.
Cloud-based storage sites, on the other hand, allow users to upload their data to a remote device accessible via the Internet. Files uploaded to sites are stored in data centers and are themselves backed up redundantly. Depending on the service used, users get the benefit of additional security features and data encryption as part of the package. This method of secure data storage, however, is often limited by the amount of data space the service allows per user. Users with large files often have to pay extra to secure more space.
In addition to remote file storage, a user can ensure secure data storage by applying data encryption to both the primary data drive and backup files. This prevents any malicious actions by remote users, such as stealing or modifying files. Users can integrate data encryption with antivirus applications to protect their files from malware.
Secure data storage can also be improved by separating the operating system and applications from user data. Users are encouraged to have two hard drives: the first disk should contain the operating system and applications needed to run the computer, while the second disk contains all of the user’s electronic files and documents. Malicious programs and users often target devices that contain the operating system and applications; storing user files on completely separate devices effectively protects user data from damage.
