Dell为韩国产业银行下南数据中心重建数据备份与网络隔离恢复体系

Dell Technologies Korea said on Oct. 13 that Industrial Bank of Korea (IBK) has rebuilt its data backup infrastructure at its Hanam Data Center using Dell solutions.
IBK established a new backup system to protect and recover enterprise-wide data as it migrated its information technology (IT) systems to the Hanam Data Center. The new facility features approximately three times the network traffic capacity of the previous data center and fully redundant power supply networks to improve reliability.
The bank previously relied on tape-based backup libraries to protect its data, but faced management burdens stemming from the risk of tape damage or loss and aging equipment. The technology also limited the speed of data retrieval and recovery. IBK additionally needed an environment where backup data could be isolated in a separate area, allowing rapid recovery using trusted data even in the event of a cyberattack.
To address these challenges, IBK deployed Dell PowerProtect Data Domain DD9400 and DD9900 appliances, Dell PowerProtect Cyber Recovery, and Dell NetWorker to establish data backup and replication capabilities alongside a disaster recovery (DR) environment.
The system incorporates air-gap technology, which physically or logically isolates data completely from external networks. An IBK official said the bank conducted a proof of concept (PoC) prior to the project, comparing backup performance and processing times with competing solutions before selecting Dell's products.
The system covers enterprise-wide data—including the bank's account-processing, information, operations, services, and individual business systems—and creates three backup copies in addition to the original data. After completing the first high-speed local backup at the Hanam production data center, the data is replicated to a separate off-site center in Seoul for a second backup, and then to a third backup location for disaster recovery.
When replicating data to the Seoul off-site backup center and the DR center, IBK applied air-gap and Retention Lock technologies through Dell PowerProtect Cyber Recovery. Retention Lock prevents backup data from being arbitrarily deleted or modified, protecting information against ransomware, hacking, and operational errors.
IBK also installed racks designed to protect against electromagnetic pulse (EMP) events at its off-site backup center. The racks provide electromagnetic shielding against external interference and fire-resistant protection for internal equipment to maintain business continuity during physical disasters.
According to Dell Technologies Korea, the new infrastructure enables IBK to support diverse database environments from multiple vendors through a single integrated backup solution. Deduplication and compression capabilities in Dell PowerProtect Data Domain have achieved a data reduction ratio of about 44:1 in actual production operations, helping the bank reduce storage space and data center footprint.
