資訊安全貼士 (2023年11月號) - 守護數位資產: 數據備份指南
To: All Users
Important data loss can occur anytime, data backup is an important measure to prevent data loss caused by equipment failure or data damage, ensuring valuable information will not be lost forever. Data backup also provides the last protection for cyberattacks (especially ransomware attacks), allowing you to recover the data and resume daily operations quickly. Proper data backup can also protect sensitive personal and financial information from unauthorized access or disclosure.
Basic Data Backup Practices:
- Regular Backup: Schedule regular backup to ensure your data is always up to date. Daily backup is recommended for critical data, weekly or monthly backup may be sufficient for files that are not updated frequently.
- Keep Multiple Backup Copies: Store multiple copies of your backup on different storage devices, such as external hard drives, cloud storage, or even physical copies. This redundancy ensures that even if one of the storage media failed, your data can still be preserved. When using cloud storage, please pay attention to the security and data protection settings of the service and consider which data is suitable for storage in the cloud.
- Store Storage Devices Properly: Store your backup storage devices properly and away from physical hazards like fire or water. For cloud storage, choose reputable providers with robust security measures.
- Test Backup Regularly: Verify the integrity of the backup by testing them regularly to ensure the data can be restored when necessary.
- Password Protection: Protect your backup devices by means of a password to prevent unauthorized access. In addition, consider encrypting the backup to increase the security.
Data backup is not a one-off task, but an ongoing process. Through the above basic and effective practices, you can protect your valuable data from being lost and ensure that your personal and work data are protected.

各位用戶:
重要資料遺失時有發生,及時為數據備份是防止設備故障或數據損壞而造成資料遺失的重要手段,以確保珍貴的資料不會永遠遺失。數據備份還為網路攻擊(尤其是勒索軟件攻擊)提供最後一道保護防線,讓您可以快速恢復數據並回復日常運作。正確地備份數據還可以保護敏感的個人和財務資料,免受未經授權的存取或洩露。
基本的數據備份實踐:
- 定期備份:安排定期備份以確保您的數據是最新的。對於關鍵數據,建議每天進行備份,而對於不經常更新的文件,可能每週或每月備份就足夠了。
- 保留多個備份副本:將備份的多個副本儲存在不同的儲存裝置上,例如外部硬碟、雲端存儲,甚至是實體副本。這種冗餘能確保即使其中一個儲存媒體發生故障,您的數據仍然得以保留。當使用雲端存儲時,必須注意服務的安全性及資料保護設置,並考慮哪些資料適合存儲在雲端。
- 妥善放好存儲裝置:將備份存儲裝置妥善存放,遠離火源或水源等物理危害。對於雲端存儲,請選擇具有健全安全措施及信譽良好的供應商。
- 定期測試備份:透過定期測試備份來驗證備份的完整性,以確保在需要時可以還原數據。
- 密碼保護:使用密碼保護您的備份裝置以防止未經授權的存取。此外,還可以考慮加密備份以增強安全性。
數據備份並不是一次性的任務,而是一個持續的過程。透過以上基本而有效的實踐,可以保護您的寶貴數據免於遺失,並確保您的個人資料和工作資料得到保障。
