Additional hard disk will be installed to the server. Data stored in the main hard disk will be copied to the extra backup hard disk by conjob. Customers could set the number of copies of your backup (i.e. if 3 days backup are required, the backup of the 4th day will be replaced the data of 1st day), and could get the backup data if need.

Daily Backup Service:
 
Additional hard disk will be installed to the server. Data stored in the main hard disk will be copied to the extra backup hard disk by conjob. Customers could set the number of copies of your backup (i.e. if 3 days backup are required, the backup of the 4th day will be replaced the data of 1st day), and could get the backup data if need. 


Hardware Backup
 
RAID technology combines two or more physical hard disks into a single logical unit. With Raid protection, hard disk in the server will be divided into 2 groups: Main Hard disk and backup hard disk. When data is input to the main hard disk, the same data will be also input to the backup hard disk. If the main hard disk failed to operate, the backup hard disk will replace the work of the main hard disk. This technology provides users a sufficient time to replace the failed hard disk and prevents the loss due to the failure of hard disk.     

RAID 1
  Two (or more) disks with each stores exactly the same data, at the same time, and at all times. Like a mirror, when data is input to the main hard disk, the same data will be also input to the backup hard disk. If the main hard disk failed to operate, the backup hard disk will replace the work of the main hard disk. However, no matter how many hard disk is in the server, only the main hard disk will be counted as the storage space of the server (e.g. Two 500GB hard disk works with Raid, but only 500GB space could be used for input data) 

RAID 5
 

RAID 5 combines three or more disks in a way that protects data against loss from any one of disks. When data is input to the server, the data will be separated and stored into the hard disks. Therefore, Raid 5 could increase the storage of the server (e.g. three 500GB Hard disk works with Raid, total 1000GB space could be used for input data.) If one of the hard disk is failed to operate, the system will rebuilt the data and the server could still work in normal status.




Backup Server
 
Backup server provides you a higher level of protection. Two servers with same environment (including hardware and software) will be connected with Network Card, when the main server fails to operate, the backup server will work and replace the main server, which ensures the website and email system will not be affected.
