Rep. Jin Jong-oh said, “The actual scale of data loss and recovery must be thoroughly investigated and made public.”

(Seoul = Yonhap News) Reporter Kwon Hee-won = After the fire at the Daejeon Center of the National Information Resources Agency last year, the government announced that 709 systems were 100% restored, but it was pointed out that this was only the percentage of normal operation of the system and had nothing to do with the actual percentage of recovered data.

According to data submitted by People Power Party lawmaker Jin Jong-oh, a member of the National Assembly Public Administration and Security Committee, from the National Information Resources Agency on the 6th, the total data of 709 systems that failed due to fire last year was 878.36 terabytes (TB).

Among these, the government business storage space 'G Drive' that was completely burned down was 868TB, or 98.82% of the total, and the data of the remaining 708 systems was 10.36TB (1.18%).

G Drive is a business storage space used by about 190,000 public officials from 74 organizations, including central administrative agencies. At the time of a fire, the original and backup were stored in the same place and no dissipative backup (a backup method of distributing data in preparation for disasters, earthquakes, etc.) was used, making it impossible to recover data from G Drive itself.

The Ministry of Public Administration and Security announced on December 30 last year that 709 systems affected by the fire had been '100% restored', but it was found that G Drive, which was virtually impossible to recover existing data, was replaced with a new system and included in the recovered system.

In other words, Rep. Jin said that the '100% recovery' announced by the government was based on normal operation of the system, not data recovery.

Some ministries have recovered business data stored in G Drive on their own, but the actual extent of data damage for all 74 organizations that used G Drive has not been comprehensively determined.

In the case of the Ministry of Personnel Management, out of the 23,618,463 files stored in G Drive, 5,242,746 (22.2%) were recovered using data remaining on the PC, but 18,375,717 were not recovered.

Rep. Jin pointed out, "Restarting the system and recovering lost business data are completely different issues," and added, "The government should not just tout the number '100% recovery,' but should fully investigate and disclose the actual scale of data loss and recovery from 74 organizations."
