Fig. 1 is the method flow diagram of mobile terminal records backup of the present invention.Now in conjunction with Fig. 1, the method that mobile terminal records of the present invention is backed up describes, and is specific as follows:
Step 101: receiving record backup instruction;
Portable terminal can receive the record backup instruction of User input, afterwards executive logging backup; Perhaps the default record backup time of portable terminal internal condition produces the record backup instruction, after portable terminal receives the inner record backup instruction that produces, and the executive logging backup.
Step 102: the higher record set of selection priority is first record set from backup record collection and record set to be backed up according to arranging, and another is second record set;
The set of not storing many records in the backup medium into temporary in the portable terminal is record set to be backed up, and the set of many records of storing in the backup medium of portable terminal is the backup record collection.Every record that record set to be backed up or backup record are concentrated all includes the sign that represents its feature.In embodiments of the present invention, backup medium can adopt existing storage medium for being used for the storage medium of backup mobile terminal records.
The first priority instruction was set before this step, and the first priority instruction is the instruction that the priority of backup record collection is higher than the priority of record set to be backed up, perhaps is higher than the instruction of the priority of backup record collection for the priority of record set to be backed up.Portable terminal is selected the higher record set of priority according to the first priority instruction that arranges from backup record collection and record set to be backed up be first record set, and the record set that then priority is lower is second record set.The higher record set of priority can be the higher record set of importance, just the set of many more important records that need store of user.The first priority instruction of above-mentioned setting can be user's setting.
Step 103: judge whether there is the identical record of sign in first record set and second record set, if, execution in step 105, otherwise execution in step 104;
First record set and second record set are compared one by one, judge whether there is the identical record of sign in first record set and second record set, if, execution in step 105; Otherwise, represent that the record that first record set and second record set comprise is inequality, execution in step 104.
Judge and whether have the identical record of sign in first record set and second record set, whether the sign of the record in the sign of just judging the record in first record set and second record set is identical, has identical record if having identical sign then represent in first record set and second record set.
Step 104: as the first duplicated record collection, execution in step 108 afterwards with first record set and second record set;
All that comprise in first record set and second record set are recorded as the first duplicated record collection, and execution in step 108 afterwards.
Step 105: judge whether to adopt very first time principle, if, execution in step 106, otherwise execution in step 107;
Can in portable terminal, arrange in advance and adopt very first time principle; Very first time principle has higher priority for the modification time of record apart from the nearer record of backup time.Portable terminal judges whether to adopt very first time principle, if, execution in step 106, otherwise execution in step 107.
Step 106: with first record set and the different record of the second record centralised identity, and first record set and the acceptance of the bid of second record set sensible with modification time apart from the nearer record of backup time as the first duplicated record collection, execution in step 108 afterwards;
Owing to adopted very first time principle, therefore, the records that first record set is different with the second record centralised identity are as the first duplicated record collection; Sensible with the different record of modification time with the acceptance of the bid of second record set for first record set, the modification time of first record set and the sensible record together of second record set acceptance of the bid is compared the record of selecting modification time to concentrate as first duplicated record apart from the nearer record of backup time.
Step 107: with first record set, and second record set in the record different from the sign of first record set as the first duplicated record collection, execution in step 108 afterwards;
Because not adopt very first time principle, first record set be the higher record set of priority, therefore, with first record set, and second record set in the record different from the first record centralised identity as the first duplicated record collection.Second record set comprises the record with the sign equivalent modifications asynchronism(-nization) of first record set, but owing to do not adopt time principle, and take first record set as priority higher record set, then not to backing up with the record of the sign equivalent modifications asynchronism(-nization) of first record set in second record set.
Step 108: replace the backup record collection with the first duplicated record collection, execution in step 109 afterwards;
Portable terminal backs up to backup medium with the first duplicated record collection, just with the backup record collection in the first duplicated record collection replacement backup medium.
Step 109: finish.
Because user misoperation or mobile terminal system go wrong, may cause and keep in losing of record set in the portable terminal, at this moment need the record of portable terminal is recovered, the backup record collection that the record backup method that adopts Fig. 1 can be obtained returns in the portable terminal.The method flow diagram that Fig. 2 recovers for mobile terminal records of the present invention.Now in conjunction with Fig. 2, the method that mobile terminal records of the present invention is recovered describes, and is specific as follows:
Step 201: receiving record recovers instruction;
The record that portable terminal receives User input recovers instruction, afterwards executive logging recovery process.
Step 202: the higher record set of selection priority is the 3rd record set from backup record collection and the temporary record set of portable terminal according to arranging, and another is the 4th record set;
The duplicated record collection is the set that is stored in many records in the backup medium; The temporary record set of portable terminal is the set of many records that back up temporary on the portable terminal.
The instruction of second priority was set before this step, the instruction of second priority is that the priority of duplicated record collection is higher than the instruction that portable terminal is kept in the priority of record set, and perhaps the priority for the temporary record set of portable terminal is higher than the instruction of the priority of duplicated record collection.Portable terminal is selected the higher record set of priority according to the second priority instruction that arranges from backup record collection and the temporary record set of portable terminal be the 3rd record set, and the record set that then priority is lower is the 4th record set.The second priority instruction of above-mentioned setting can be user's setting.
Step 203: judge whether there is the identical record of sign in the 3rd record set and the 4th record set, if, execution in step 205, otherwise execution in step 204;
The 3rd record set and the 4th record set are compared one by one, judge whether there is the identical record of sign in the 3rd record set and the 4th record set, if, execution in step 205, otherwise, represent that the record that the 3rd record set and the 4th record set comprise is inequality, execution in step 204.
Judge and whether have the identical record of sign in the 3rd record set and the 4th record set, whether the sign of the record in the sign of just judging the record in the 3rd record set and the 4th record set is identical, has identical record if having identical sign then represent in the 3rd record set and the 4th record set.
Step 204: as the recovery record collection, execution in step 208 afterwards with the 3rd record set and the 4th record set;
All that comprise in the 3rd record set and the 4th record set are recorded as the recovery record collection, and execution in step 208 afterwards.
Step 205: judge whether to adopt second time principle, if then execution in step 206, otherwise execution in step 207;
Can be arranged in portable terminal in advance in the record recovery process and adopt second time principle, second time principle is that nearer record has higher priority to the modification time that records apart from recovering constantly.Portable terminal judges whether to adopt second time principle, if, execution in step 206, otherwise execution in step 207.
Step 206: with the 3rd record set and the different record of the 4th record centralised identity, and the 3rd record set and the acceptance of the bid of the 4th record set sensible with modification time apart from recovering constantly nearer record as the recovery record collection, execution in step 208 afterwards;
Owing to adopted second time principle, therefore, the records that the 3rd record set is different with the 4th record centralised identity are as the recovery record collection; Sensible with the different record of modification time with the acceptance of the bid of the 4th record set for the 3rd record set, the modification time of the 3rd record set and the sensible record together of the 4th record set acceptance of the bid is compared the record of selecting modification time to concentrate as recovery record apart from the constantly nearer record of recovery.
Step 207: with the 3rd record set, and the 4th record set in the record different from the sign of the 3rd record set as the recovery record collection, execution in step 208 afterwards;
Owing to do not adopt second time principle, the 3rd record set is the higher record set of priority, therefore, all records in the 3rd record set as the recovery record collection, will be write down the record that the different record of centralised identity is concentrated as recovery record with the 3rd in the 4th record set.The 4th record set comprises the record with the sign equivalent modifications asynchronism(-nization) of the 3rd record set, but owing to do not adopt time principle, and be the higher record set of priority with the 3rd record set, then not to recovering with the record of the sign equivalent modifications asynchronism(-nization) of the 3rd record set in the 4th record set.
Step 208: replace temporary record set with the recovery record collection, execution in step 209 afterwards;
Portable terminal utilizes the recovery record collection to replace the temporary record set of portable terminal.
Step 209: finish.
Fig. 3 is the device of mobile terminal records backup of the present invention.Dotted line among Fig. 3 represents control instruction, and solid line represents record.Now in conjunction with Fig. 3, the device that mobile terminal records of the present invention is backed up describes, and is specific as follows:
