Server and terminal shown in Fig. 3 as shown in connection with fig. 2, the embodiment of the present application provide a kind of data backup
Method, referring to fig. 4, Fig. 4 are a kind of flow diagram of the method for data backup that one embodiment of the application provides.Its
In, as shown in figure 4, a kind of data back up method that one embodiment of the application provides may include:
S401, terminal obtain the backup request and the first User Identity of the first user, and the backup of first user is asked
It asks for requesting to back up the first user data.
Specifically, user, after terminal completes operation, user is needed to back up by user's logon data standby system, terminal
Data, User Identity and backup request are sent to server.It is illustrated below with reference to Fig. 5, data backup system
Display interface content can be such as, but not limited to as shown in Figure 5.As shown in figure 5, data backup system interface 500 includes: text
Frame 501, the data for needing to back up for showing user；Backup button 502 is used to indicate the backup request of user；Exit button
503, it is used to indicate user and abandons Backup Data.Further, if user selects backup button, terminal is by the backup request of user
It is sent to server.
S402, terminal send the backup request and the first User Identity of the first user, and server receives the first user
Backup request and the first User Identity.
S403: server determines backup scenario according to the identity and backup request of first user.
Optionally, backup scenario include: one or more storage system of backup, it is backup quantity, main storage system, standby
Storage system and backup delay time.
Wherein, storage system includes the storage such as solid state hard disk (solid state disk, SSD), distributed memory system
System.Different user has different backup requirements, and server is stored with the corresponding storage scheme of different user identity.Backup
Storage system be determined according to user demand, for example, the backup requirements of user 1 are as follows: user data needs are backuped to and deposited
Storage system A and storage system B；The backup requirements of user 2 are as follows: user data need to backup to storage system A, storage system B and
Storage system C.
Specifically, server is stored with the corresponding backup scenario of different user, it is illustrated below with reference to table 1, data
The storage content of standby system can be such as, but not limited to as shown in table 1:
Table 1
Table 1 is it is found that the corresponding backup scenario of user that user identifier is 001 are as follows: user data is backuped to storage respectively
System A and storage system B, the quantity of backup are all 1 part respectively, and wherein storage system A is main storage system, and storage system B is
Standby storage system is 30s for the backup delay time between storage system；The corresponding backup side of user that user identifier is 002
Case are as follows: user data is backuped to storage system A, storage system B and storage system C respectively, the quantity of backup is all 1 respectively
Part, wherein storage system A is main storage system, and storage system B and storage system C are standby storage system, between storage system
The backup delay time be 30s.
S404, server establish connection according to the backup scenario and one or more of storage systems.
Specifically, including the storage system that user needs to back up in backup scenario, server needs that backs up to deposit with user
Storage system establishes connection, backs user data to corresponding storage system convenient for subsequent.
For example, user's storage scheme that identity is 001 is that user data is backuped to storage system A and storage respectively
System B, therefore server and storage system A and storage system B establish connection.
S405, server is by the first user data backup to one or more of storage systems.
Optionally, if in the backup scenario of the first user including a standby storage system, the server is by the first user
Data backup to one or more of storage systems, comprising:
Be engaged in device the first moment will first user data backup to the main storage system, the second moment will described in
For first user data backup to the standby storage system, the time interval at first moment and second moment is described standby
Part delay time.
Optionally, if in the backup scenario of the first user including multiple standby storage systems, the server is by the first user
Data backup to one or more of storage systems, comprising:
Server is determined according to the backup space and remaining space capacity of first user data occupancy storage system will
For first user data backup to the backup sequence of the multiple standby storage system, the storage system includes one or more
A backup space；
Server successively backups to the first user data according to the backup sequence and the backup delay time described
Multiple standby storage systems.
Specifically, each storage system includes one or more backup space, each backup space has corresponding remaining empty
Between capacity.Server determines that user data backup arrives storage system in the logical address where terminal according to the first user data
Logical address, then according to the logical address of storage system determine the first user data in the correspondence backup space of storage system,
For example, storage system B and storage system C are standby storage system, and the user data is corresponding in the corresponding backup scenario of user 002
The backup space for backuping to storage system B is backup space 1, and the residual capacity size of backup space 1 is 30G；First number of users
It is backup space 1 according to the corresponding backup space for backuping to storage system C, the residual capacity size of backup space 2 is 40G.
Optionally, server according to first user data occupy the backup space memory size and the backup
The sequence of the ratio of Spatial Residual spatial content size from small to large is ranked up the multiple standby storage system, after arrangement
Sequence be determined as multiple standby storage systems backup sequence.
Specifically, the storage strategy due to storage system is different, identical user data size backups to difference
Size after storage system can be identical or not identical.
For example, the user data backup of user 002 occupies the memory size of backup space 1 to storage system B backup space 1
For 0.5G, backuping to storage system C backup space 1 and occupying the memory size of backup space 2 is 0.4G.The number of users of user 002
Ratio according to the 1 remaining space amount of capacity of memory size and backup space for occupying the backup space 1 is 1/6, described in occupancy
The ratio of the 2 remaining space amount of capacity of memory size and backup space of backup space 2 is 1/10, so storage system B and depositing
The backup of storage system C is storage system B → storage system C.
Implement the embodiment of the present invention, server backs user data to one or more according to the backup scenario of user and deposits
Storage system avoids user from repeatedly carrying out data backup to different storage systems, reduces the user data backup time, effectively improves
User data backup efficiency.
Referring to Fig. 6, Fig. 6 is a kind of flow diagram for data back up method that one embodiment of the present of invention provides.Clothes
Be engaged in device by the first user data backup to storage system when, further include following steps S406-S413.Below to step S406-
S413 describes in detail:
S406, terminal obtain modification instruction, and the modification instruction is used to indicate the first user request to the first user data
Partial data or total data modify operation；
Specifically, terminal is after the backup request for obtaining user, it is understood that there may be modify to the first user data
Operational circumstances.For example, being illustrated so that the first user backs up mass picture as an example.First user asks in transmission backup
After asking, which, which can be carried out, for example deletes a certain or more photos, is put into the modifications such as other photo operation.
S407, terminal send modification instruction, and server receives modification instruction.
S408, server instruct partial data or total data after modifying operation to backup to one according to modification
Or multiple storage systems.
Specifically, the modified modification data of the first user are backuped to storage system rather than by whole the by server
One user data backup is to storage system.
Optionally, server will modify operation after partial data or total data backup to one or more and deposit
Storage system, comprising:
