A backup malfunction results in the loss of 77 terabytes of research data at the university.

Due to an accident in the backup system of Kyoto University’s Hewlett-Packard supercomputer, around 77TB of research data has been wiped out in Japan.

When it happened, 34 million files from 14 research groups were lost, along with the backup, on December 14-16, 2021.

The institution found that the work of four affected groups could no longer be restored after an investigation to establish the consequences of the loss.

The event has been reported to all impacted individuals individually by email, but no information has been released about the type of work that was lost.

The backup procedure has been halted for the time being. The university has decommissioned the backup system and hopes to reintroduce it in January 2022 to avoid data loss from occurring again.

In addition, to complete backup mirrors, the objective is to preserve incremental backups, which only cover files that have changed since the last backup.

The cost of supercomputing is high.
Supercomputer research costs several hundred dollars per hour, therefore this occurrence must have caused concern to the impacted groups, even if the specifics of the lost material were not made public.
Research at Kyoto University is regarded as one of Japan’s most important and receives the second-highest funding from the country’s government.

Chemistry, where it is ranked fourth in the world, is where it really shines, but it also makes contributions to other fields including biology, pharmacology, immunology, materials science, and physics.

The incident and its influence on research groups have been asked by Kyoto University, but we have not received a response as of yet.

Leading the field is Japan.
The Riken Center for Computational Science in Kobe, Japan, is home to the world’s most powerful supercomputer, dubbed “Fugaku”

Fujitsu’s Fugaku exascale system is capable of 442 PFLOPS of computational performance. IBM’s “Summit” ranks second on the global list, with a maximum capacity of 148 PFLOPS.

Fugaku has been utilised for COVID-19 research, diagnostics, treatments, and virus transmission simulations, at a cost of $1.2 billion.
