Currently, XB is the most significant data storage unit, and the most commonly used storage units are MB, GB, and TB. Today we have entered the age of ZB data.

World Backup Day is celebrated on March 31st to spread knowledge about backup and data storage.

▮ What is a Backup?

Backup protects information stored on electronic devices such as mobile phones and computers to prevent data loss and irreparable loss due to device damage.

These data include:

  • Personal photos, videos, documents, contacts, short messages;
  • Enterprise server operating systems, application software, databases, etc.

The embarrassment of data loss:

  • The lost phone lost hundreds of customer numbers…
  • Broken camera memory card, missing 10 gigabytes of wedding photos…
  • With such ransomware, I lost three years of blueprints on my computer…
  • A misguided British teenager accidentally dropped a hard drive and lost £75m worth of bitcoin…

▮ 3-2-1 backup principle

  • Keep at least three copies of the same data, including the original data;
  • Save to more than two storage media, such as CD-ROM and hard disk;
  • At least one remote backup can be restored after a local disaster.

▮ What are the units of storage capacity?

We often see that a file of how many KB, a photo of tens of MB, and a film of a few gigabytes is the storage capacity of the computing unit.

In the computer class examination, the standard storage unit-related test questions for example:

Which of the following storage units is the largest (B)

▮ Data storage capacity unit conversion ratio

1DB = 1024NB

It can be seen that the conversion relation between each storage unit and its superior unit is 1:2^10(1024), which is:

1KB=2^10B=1024B, 1MB=2^10KB=1024KB ….

▮ Global data volume and growth

Currently, XB is the largest data storage unit, but the specific abbreviation for X was not found anywhere in the world. I think the answer will be when the total amount of global data is larger. Most commonly, MB, GB, and TB are used. We are currently in the age of ZB data.

It is reported that the total scale of global data reached 44ZB in 2020.
