The invention discloses a data organization method for a
backup service
software storage
server side for improving data organization and
data management efficiency of the storage
server side. The method comprises the following steps: (1) initializing a storage space of the storage
server as a
metadata area (comprising main
record, index head and data index) and a data area; (2) receiving and judging a user operating command, sequentially performing a
backup operation, recovering the operation and turning to step (4), and canceling the operation and turning to step (5); (3)
processing a user
backup operation, backing up user data to the data area of the storage server, meanwhile avoiding repeated data backup by using repeated data canceling technology, and turning to the step (2); (4)
processing the
recovery operation, positioning and searching a recovered data
list specified by a user in the data area of the storage server, then transmitting the recovered data
list to a user side, and turning to the step (2); and (5)
processing the canceling operation, searching the canceled data specified by the user, introducing counting according to backup data blocks of the data in the data area of the storage server to perform corresponding processing, and turning to the step (2). The method improves the
utilization rate and manageability of the storage
server side and the expandability of the
system, saves the network bandwidth, and improves the backup efficiency.
