And improve the experience effect of user.
S102 carries out Hash calculation to the content of each above-mentioned file respectively, obtains cryptographic Hash corresponding with each file；
Wherein, the cryptographic Hash calculation of each file can be calculated using SHA256 hash function.
Based on example mentioned above, it is assumed that the file of entitled case history on the 5th in March includes: the case history in A March 5
File, the patient file and C patient file on March 5 in B March 5, then the first data are as follows: the text of entitled case history on the 5th in March
Part presss from both sides included data, can carry out calculating generation Hash to each file in the first data by SHA256 hash algorithm
Value, as shown in table 1.
Each file puts in order and corresponding cryptographic Hash in the patient file folder in table 1 March 5
| The patient file on March 5 presss from both sides | File puts in order in file | Cryptographic Hash |
| The patient file in A March 5 | 1 | Cryptographic Hash A |
| The patient file in B March 5 | 2 | Cryptographic Hash B |
| The patient file in C March 5 | 3 | Cryptographic Hash C |
S103 puts in order according to above-mentioned the default of multiple files, spells to the corresponding cryptographic Hash of above-mentioned multiple files
It connects, obtains fisrt feature information；Above-mentioned fisrt feature information is used to characterize the data characteristics of above-mentioned first data.
Wherein, it is above-mentioned it is default put in order can be understood as it is pre-set put in order, this, which puts in order, is understood that
For the sequence arranged according to chronological order, it is understood that it is the sequence arranged according to the byte number of file,
It can be appreciated that be ranked up according to the sequence of the initial of file name etc..The embodiment of the present invention does not limit this.
In order to be more clear to the description of this step, now it is described based on above-mentioned example, in shown in above-mentioned table 1
Hold, if cryptographic Hash A be 8d96, cryptographic Hash B be 9eef, cryptographic Hash C be 6eca, according to each file March 5 patient file
Folder puts in order, and carries out head and the tail splicing, spliced result are as follows: cryptographic Hash A cryptographic Hash B to the corresponding cryptographic Hash of each file
Cryptographic Hash C, i.e. 8d969eef6eca, then 8d969eef6eca is exactly the fisrt feature of the file of north doctor's case history on the 5th in three institute's March

Step D obtains second feature information；Wherein, above-mentioned second feature information is used to characterize the data spy of the second data
Sign；Above-mentioned second data are to the last Backup Data of above-mentioned source data, and the BACKUP TIME of above-mentioned second data is above-mentioned
Before first data；
It for the ease of the understanding to the second data, now gives an example, if backing up to the case history of patient H, carries out one within 7 days
Secondary full backup, the incremental backup of progress in 2 days, then from the case history timing in first day for generating patient H, first at the 7th day pair
The case history of patient H carries out full backup, then the first data are exactly the full backup data of patient H, at this time due to not to patient H
Case history carry out incremental backup data, therefore at this time only have full backup data as the first data, then at the 9th day, to disease
Case history during people H the 8th day to the 9th day carries out incremental backup, and the full backup data that the 7th day at this time when backs up are as the second number
According to the incremental backup backed up during the 8th day and the 9th day is the first data；At the 11st day, to patient H the 10th day and the 11st day
The case history of period carries out incremental backup, then the 9th day incremental backup data is the second data, then the 11st day incremental backup is the
One data.
Based on the above-mentioned description to the second data, when the second data are full backup data, second feature information is table
Levy the information of the data characteristics of full backup data, it can be understood as the cryptographic Hash of each file is according to text in full backup data
The spliced data of sequence of the part in full backup data file；When the second data are incremental backup data, second feature
Information is to characterize the information of the data characteristics of incremental backup data.
Above-mentioned first data are included by step E according to default the putting in order of above-mentioned the included file of first data
The cryptographic Hash of each file is spliced to the end of above-mentioned second feature information.
Based on the example of above-mentioned second data description, when the second data are full backup data, full backup data packet
Three files are included, if the cryptographic Hash of three file generateds, respectively d3c2,9a3a and 280e, then second feature information is
d3c29a3a 280e；When the first data are incremental backup data, and incremental backup data file includes two files, this two
The cryptographic Hash of a incremental backup file is respectively 686c, f0c3, then fisrt feature information is d3c29a3a280e686cf0c3, when
When second data are incremental backup data, then second feature information is d3c29a3a280e686cf0c3, the incremental backup of calculating
Data are f5d5, then fisrt feature information is d3c29a3a280e686cf0c3f5d5.
As it can be seen that this implementation passes through each in the second data that will be calculated when the first data are incremental backup data
The cryptographic Hash of file is spliced according to each file putting in order in the second data at above-mentioned second feature information end, is obtained
