Kyoto University lost 77 TB data after software update! How to keep your critical data safe?

Recently, 77 TB of supercomputer storage data of Kyoto University was lost after a flawed HPE (Hewlett Packard Enterprise) software update to the backup script.

The incident happened between December 14-16, 2021, and over 34 million files from 14 research groups were wiped from systems and backups. After investigations on the impact, Kyoto University announced that the loss of 4 research groups’ data might be permanent. About 28 TB data cannot be recovered because of the absence of backup.

According to HPE’s apology letter, the update aims to improve file visibility and readability. However, the updated shell script overwrote the initial bash script while it was still running, causing actual files in the backup disk storage being mistakenly deleted. For this issue, HPE addressed that the company will take 100% responsibility. Kyoto University now has stopped the backup process to improve the backup architecture, and planned to reintroduce the system in January.

Time doesn’t kill the value of data. Especially in some specific fields like exploration, research & development, and meteorology etc., the value of data even grows higher as time goes by, because the long-term kept research files and information usually helps people better explore the unknown. Therefore, in today's digital information world, to have data--even those that may not be frequently used--properly saved, needs to be a top concern. Learned from Kyoto University’s data loss case, backing up critical data to another system is important--this can be a life-saver for IT admins in almost all industries, and a reliable third-party data protection assistant like Vinchin Backup & Recovery can help by building an isolated backup environment with 3-2-1 backup strategy implementation to enhance the security and usability of backups.

 

· 3 backups: Image-based, incremental backup

Vinchin Backup & Recovery offers agentless, image-based incremental backup to protect TB/PB size data via LAN-Free transport or separated backup network, requiring less computing resource consumption and 0 production network traffic. Users can get initial backups easily by creating automated, stable, and efficient backup jobs in minutes through a web-based management console.

· 2 backup media: Archive backups to cloud

In enterprise-grade data protection, for files that needs to be kept for a long time, cloud could be the best place for them to stay. Vinchin Backup & Recovery offers Cloud Archive for users to save archive data on desired cloud storage for long-term data retention, so that you can easily transfer history data back to the production system when needed. This also stores highly available data resources for recovery scenarios after local production and backup environment get damaged.

· 1 backup offsite: Backup copies at remote site

Vinchin Backup & Recovery supports users to build an offsite disaster recovery center with Offsite Backup Copy. Users can easily create backup copy jobs to run after each backup job finishes, and choose offsite storage as a copy destination. All backup copy chains are 100% independent that makes no effect on the integrity of the original backups.

Data loss led by system failure is hard to predict, just like what Kyoto University had encountered this time. Let your backups simply stay in one place with the production environment doesn't mean minimal data loss risk, building a complete backup architecture with the help of a reliable backup system also matters.
