One of the top priority that every organization is concerned about is how to ensure that their information system, company’s data are always available at all time, how to avoid data loss for reasons like disasters, data deletion or theft.
Depending on the importance of data and the size of the organization that we propose a solution that best meets our client’s needs:
• Data Backup: A simple solution whereby data are copied to tape, HDD, NAS. Data are backup everyday and may be stored at another offsite location.
• Set up a backup data center and perform backup periodically: When the main center has problem, company’s data is safe but time is needed to recover system operation.
Low cost, easy to manage and operate,minimize loss when there’s disaster are advantages of the above two solutions. However, there’s still risk of losing data between two periodic backup.
• Set up a backup data center and perform online backup: This solution could overcome the limitation of the other two solutions since backup are performed continuously & automatically via high speed leased line. This solution could guarantee that 99.99% of corporate data are safe.
