Step 9: the block device where clone volume is supplied to Backup Data by network mode and uses node by memory node；
Step 10: Backup Data uses node, and the block device that carry receives directly uses.
Further, the network mode in the step 1 and step 9 includes iscsi or FC or IB.
Further, in the step 1 when data source is database, the size for the block device that memory node provides is source number
According to twice of size；When data source is file system, the size for the block device that memory node provides is identical as data source size.
It can be effectively avoided in this way because the data of data source increase, the block device off-capacity for causing us to provide.
Further, if data source operation system is Windows in the step 2, block device is formatted as NTFS lattice
Formula；If data source operation system is RHEL6, block device is formatted as ext4 format；If data source operation system is
RHEL7, then block device is formatted as xfs format；If data source operation system is suse, block device is formatted as ext3 lattice
Formula.
Working principle: the present invention obtains the data that user needs to back up according to the backup strategy of user, and wherein user's is standby
Part strategy includes data source, BACKUP TIME and frequency of your backups.After getting Backup Data, the automatic snapshot for carrying out data is protected
Demonstrate,prove the integrality of Backup Data.Automatically Backup Data is marked, guarantees the convenience of Backup Data management.Backup Data is with original
The storage of beginning state guarantees that user can directly use without secondary operation.Further according to the recovery demand of user, automatically to finger
Fixed Backup Data is cloned, and by the block device where clone volume by network mode, carry uses node to Backup Data
It uses.Data are realized without restoring, that is, can be used.It saves in actual production, data are restored the required plenty of time and set
Standby cost.
