What is Backup in Banking Operations?

According to Article 22 of Circular 09/2020/TT-NHNN (Effective from January 1, 2021) regulating backup procedures as follows:

Organizations shall perform data backup to ensure data safety as follows:

- Create a list of information systems according to the importance level that needs to be backed up, along with storage duration, backup frequency, backup methods, and system recovery checktimes from the backup data.

- Data of information systems from level 3 and above must have an automatic backup plan suitable to the data change frequency and ensure the principle that newly generated data must be backed up within 24 hours; data of the remaining information systems shall be backed up periodically according to the organization's regulations.

- Backup data of information systems from level 3 and above must be stored in external storage media (such as magnetic tapes, hard disks, optical disks, or other storage media) and safely stored, preserved separately from the area where the source information system is installed on the next working day following the completion of the backup.

- Regularly check and recover backup data from external storage media at minimum intervals:

+ Once a year for information systems from level 3 and above;

+ Once every two years for other systems.

Above is the content of backup in banking activities according to the latest regulations.

Sincerely!
