Learn the 321 backup rule: Data stored for ten years will not be lost

On the day before April Fool's Day every year, there is a lesser known holiday called World Backup Day. This festival originated from a user sharing their experience of losing hard drive data on the foreign forum Reddit. It was initiated in 2011 and was chosen to be held on the day before April Fool's Day to warn people to avoid becoming "digital fools" due to data loss.

Many friends have experienced data loss, which could be family members' video materials, important work files, or cherished film and television resources. The simple and reliable backup strategy introduced today can minimize the risk of data loss to the greatest extent possible, and it is the 321 Golden Backup Rule.

The core of the 321 backup rule can be summarized as three copies of data, two types of storage media, and one remote backup. The so-called three copies of data refer to retaining two additional backups in addition to the original data. Even if one copy is lost, there are still other copies available. Especially for data with spatiotemporal uniqueness such as real photos and videos, it is necessary to copy at least two or even more copies to minimize the risk of data loss.

Two types of storage media refer to storing data on two different types of devices, such as local hard drives and cloud storage, to avoid the loss of all data caused by a single media failure. Local hard drives are usually divided into solid-state drives and mechanical hard drives, which have different levels of data recovery difficulty. Mechanical hard drives use physical structures for data reading and writing, and related failures are often related to mechanical components, making replacement or repair relatively easy; The failure of solid-state drives is mostly related to flash memory chips, and once the chip is damaged, the technical difficulty of recovery is even higher.

It sounds like mechanical hard drives have lower data recovery difficulty, but in terms of speed, solid-state drives are much ahead. The speed of consumer grade mechanical hard drives is generally between 150 and 200MB/s, while the speed of consumer grade solid-state drives can reach 20 to 30 times that of the former. Paired with the Green Alliance Thunderbolt hard drive box, it can achieve speeds ranging from 3500MB/s to 7000MB/s, with 50GB of data storage taking as little as 8 seconds. In addition, the solid state drive is compact enough in size, and when paired with a Green Link hard drive case, it is only equivalent to the size of a mobile phone, allowing data to be read and copied anytime and anywhere; Mechanical hard drives are generally installed on desktop computers, cabinets, or hard drive bases, and are relatively less convenient to carry.

Simply put, for data types that require frequent access such as work files and study materials, storing them on a solid-state drive is convenient for quick and easy use at any time; Important image data, phone backups, and other infrequently accessed data are recommended to be stored on a mechanical hard drive. If conditions permit, both mechanical hard drives and solid-state drives can be used to backup data, balancing read speed and security.

A remote backup refers to storing a copy of data in a location far from the primary storage, such as at a friend's home or on a cloud storage device. This remote storage copy is generally used to cope with extreme situations such as fire, water immersion, theft, loss, and other natural or man-made accidents.

Overall, the 321 backup rule has been applied by many individuals, companies, and enterprises, and has been proven effective and reliable through practice. Important data and information can be backed up using this method.
