I. basic functions of using iTunes for backup

1. When will iTunes be backed up.
Every time iTunes connects to the iPhone and synchronizes it for the first time, it will automatically back up. That is to say, if your iPhone has been connected to a computer for repeated synchronization, only the first synchronization will automatically back up.
At the same time, you can manually back up data using iTunes, such:

You can cancel the backup at any time, whether it is automatic or manual backup. Some students think that backup takes too much time in the same step, only when the backup word appears at the start of synchronization, click the X button, for example:

2. What is backed up by iTunes backup?
ITunes will back up the following content on your iPhone:
Text message; images in MMS; contacts; calendar; memos; camera film; recent calls; personal favorites; sound settings; email settings, Safari settings; application settings (such as game archives and stanza books); iPhone settings
Note:
A) iTunes backup cannot back up the application itself. That is to say, when you reinstall the iPhone and restore it from the backup, your application will not appear automatically and must be installed synchronously again;
B) You cannot directly view the iTunes backup. You must use a third-party tool;
C) iTunes can only back up the content operated on the iPhone through it. If you use programs installed by the 91 assistant, their settings will not be backed up.
D) iTunes will only back up the content of a specific directory. If you use 91 file management or ifunbox to create a new directory on the iPhone and transmit music, video, and other content, these will not be backed up.
E) Your backup can be restored to any idevice, such as other iPhone and iPod Touch.
3. What are the features of iTunes backup?
A) iTunes stores backup files in the following locations:
Windows XP:/Documents and Settings/(User Name)/Application Data/Apple Computer/mobilesync/backup/
Windows Vista/7:/users/(User Name)/appdata/Roaming/Apple Computer/mobilesync/backup/
The directory is partitioned by the system. Therefore, before reinstalling the system, back up the contents.
B) iTunes backup is Incremental backup, that is to say, each backup will only back up a different location than the last one. Therefore, if you load a lot of apps or music videos at a time, iTunes needs to search for new content one by one and back up as needed, which will take a lot of backup time. In fact, I do not recommend canceling the backup during synchronization, which will take longer in the future.

Ii. backup and recovery skills

1. Can I disable automatic backup of iTunes in the same step?
Many people may be troubled by long backups in the same step. The answer is yes, which can be achieved through the back off software. Software features are simple, such:

After the feature is disabled, you can use the software to re-enable the automatic backup function. Remember, if you disable automatic backup, perform regular manual backup on your own, otherwise the problem will be terrible.
In addition, the iTunes backup time is too long, probably because of a problem with a newly installed software (most of which may be cracked software). After uninstalling the software, you will find it normal.

2. Why is the message "ITunes cannot back up the iPhone, because it cannot store the backup on a computer" displayed in iTunes backup?
If your hard disk partition is still FAT32, this problem may occur because tens of thousands of Long-name files exist in the iTunes Backup Directory, which exceeds the FAT32 folder limit.
The other cause may be abnormal backup or other iTunes faults. If you delete the previous backup, reinstalling iTunes may solve the problem.
It may also be because iTunes cannot write files because of a damaged backup folder. In this case, you need to use the disk Repair Tool.
3. How should I restore my iPhone after I refresh it?
Many people are wondering how to restore the iPhone to its original status after it is replayed. One of the prerequisites is described later, that is, you must have the same database as the original one. Another key point is to make rational use of existing backups.
To ensure this, iTunes retains only one backup generated during synchronization for each device. If the operation is not performed properly, the recovery may fail. Let's take a look at the restoration process.
After you refresh the iPhone, iTunes will automatically connect to the iPhone, and two recovery options will appear: Set to new iPhone and recover from backup.
A) after the new iPhone is set, a new backup file will be created for the device during the first synchronization.
B) if you choose to recover from backup, please note that the iPhone will first recover and then perform synchronization, this means that only basic settings (such as SMS, camera film, and Safari settings) on the iPhone are restored ), at this time, the user's application may not be synchronized to the iPhone, so this recovery is incomplete. The correct operation is to wait for the iPhone to automatically complete the synchronization, remember not to unplug the USB cable, and then move all the content in the resource library you need to the iPhone in the same step, then right-click the iPhone, select recover from backup, for example:

Use itunesto enter. jpg

In this way, you can find that all application settings are restored.
Here are two examples: stanza, which stores all the books in the documents directory, for example:

Download (4.19 KB)
Use itunesto enter. jpg

Generally, to manually back up these books, you need to use ifunbox to copy documents to the PC. If the restore operation fails, all contents in the directory will be restored to the initial state. In fact, iTunes backs up the directory, as shown in:

Use itunesto enter. jpg

Several hundred thousand in the figure are actually a book. Correct backup and recovery, you don't have to worry about the loss of books. Another example is the game archive, which will also be backed up.
So what is the wrong recovery? In contrast to the previous recovery steps, after the flash is completed, the iPhone automatically restores the backup and then automatically synchronizes the data, if you unplug the USB cable at this time, next, you will find that the iPhone starts an automatic backup, which will overwrite the original one because your iPhone is in the current state, for example, there is no game archive, so that the game archive will be lost in the last backup.
4. How do I delete an existing backup? Can I use iTunes backup on another computer?
Multiple backups may be retained in iTunes. You can view the backups in "Edit/preference settings/devices" in the iTunes menu and delete unnecessary backups, as shown in:

You can also manually delete these backups by entering the backup storage directory. Note that the backup time is displayed at the end of the directory name, as shown in:

Use itunesto enter. jpg

Can you transfer these backups to iTunes on other PCs? The answer is yes. You can also manually keep these backups. If you reinstall the system, you only need to copy the backup to the corresponding directory again. Note that the version of iTunes cannot be lower than the version used to create a backup.

3. Use a third-party tool to process backups

Many people are asking, is there a way to extract contacts from the backup directly? Some people want to view the text message records in the PC, but iTunes is all database files and you cannot directly view them.
Here I will recommend two tools, itwin and ibackupbot.
1. Let's talk about itwin first.
This is simpler and the processing speed is quite fast. The first time you run the software, it may be in German, but don't worry. It supports Chinese.

For the first use of the bird language, refer to and modify it to simplified Chinese:

You can also select a specific backup time in the settings:

Now you can directly view the contact person, text message, and other information. Note that because it is a free version, you can only see the first three messages, but this does not affect your export of messages.

On the export tab, you can choose to export the required information to a specific format.

The interface of this tool is beautiful and the processing speed is quite fast. We recommend that you use this tool. However, it cannot process all the backup information.
2. ibackupbot is a very powerful backup processing software.

This website also has a heavyweight software that you can explore on your own.

This software is amazing. Through backup operations, you can even modify some of the content in the iPhone that has not been jailbroken. Of course we cannot use this depth here.
First install and open the software,

All the backups in iTunes are listed on the left. You can click here one by one or expand it to view the content of a specific application. The backup iPhone information is displayed on the right. Note that this is displayed as a directory. The directory structure is exactly the same as that in the iPhone, therefore, you can even extract a single file from the backup according to the directory.
The functions we need are basically on the menu button:

Unlike itwin, this software can enable iTunes backup stored elsewhere on the hard disk, so that you can view the content even if you only have backup in your hands. We can also use this software to export and import backups. The free version of this software is actually full-featured, but when using some features, the information to be registered will pop up, don't worry about it, click Cancel to exit.
Click the fifth text message button to export one or all text messages, or even delete sensitive text messages directly in the backup.

The restore button is enhanced, as shown in:

With it, you can even restore a single file in the backup to the iPhone, or restore the file modified in the backup to the iPhone. You may be wondering what the modified file is? Ibackupbot integrates a very useful modification tool, which can be used to modify memos. You can easily add a large number of texts to the memos in the backup, then use the recovery function here to restore the record to the iPhone. Of course, it may be more convenient to jailbreak.

At the same time, the plist editor is integrated in ibackupbot, which can be used to directly modify the iPhone settings without jailbreak. As programming is involved, I am just a bit confused. I will not talk about it here. Please help me to add this method.
How to use this tool, you will have a clear view of the iTunes backup.

4. database usage skills

After talking about the backup, I have to talk about the database. In fact, after I refresh the iPhone, I have to completely restore the iPhone. Backup and database are indispensable. But first, you need to separate the two. In fact, the database class is similar to the original material, and backup, even where your video is stored, can be recorded.
In fact, using a database is not very in line with the habits of the Chinese people. Of course, if you understand it, you will find that the database is actually quite convenient, because Apple wants to use its database to build iTunes into a media platform.

You may have read a lot in the database, but sometimes the projects you need are not displayed in the database. At this time, you can change them in "editing/preference settings:

When using a database, it is closely related to synchronization. Theoretically, all the content in the database can be synchronized to the iPhone. Here, we need to remind you that there is a special case that both backup and database have nothing to do with the "Photos" during synchronization. That is to say, you must manage the photos on the iPhone. OK. Next we will discuss the resource management skills in the database.
1. How to add resources to a database? Where is the database located?
This may be a very Mars issue, but it is interesting to think about the significance behind it.
The default database location is C:/users/user name/music/iTunes media. In my music, it is recommended that you use the database as another partition to avoid the loss of content in the database after the system is reinstalled. The database folder shows you:

You can specify the location of the iTunes media folder in "Edit/preference setting/advanced", for example:

It is a bit speechless that the location of your database in iTunes is often ignored by iTunes. The solution is to re-set this path every time you reinstall the iPhone. It is recommended to check the two options shown in, especially the second "Copy files to the iTunes media folder when adding files to the Database.
You must understand that iTunes manages the media files on the iPhone based on the database and has nothing to do with whether the files are backed up on your hard disk. That is to say, you must add the file to the database before synchronization. Otherwise, it is useless to copy the file directly to the folder of the database. After you hook up the options described above, you 'd better associate iTunes with files with extensions such as MP3, MP4, IPA, and m4r, both using iTunes as their default playing program. Next, When you double-click a music, ringtone, MP4 video, or iPhone app, iTunes will automatically enable it, and the file will be automatically added to the database and copied to the iTunes media folder for backup. This is the habit problem I mentioned earlier. If you reinstall the system and the iTunes media folder is still running, you only need to add the folder to the database in "file" and find the previous iTunes media folder, your database will be replied to as is. The menu is as follows:

2. Can I use multiple databases on one PC, because two iPhones need to use the same PC step?
To be honest, I have been suffering from this problem for a long time, but it is actually okay. With this feature, we can also back up the iTunes database and eliminate some iTunes faults.
First, let's look at the iTunes folder, which is also in my music:

Upload from
Download (14.42 KB)
Use itunesto enter. jpg

First, you should pay attention to the iTunes library. ITL file. If this file is deleted, your iTunes database information will be lost. There is also an iTunes music library. xml file, which is your music playlist file.
If you need to use the second database, you must first create a new database. In this case, you need to press shift and double-click the iTunes shortcut. The following window is displayed:

Upload from
Download (8.74 KB)
Use itunesto enter. jpg

Here you can select an existing database. If you need to use multiple databases at the same time, create a new database and add other music and programs to the new database. If you want to repeat the above steps with the original one, select the original iTunes library. ITL. In addition, if you want to reinstall the PC, you can also back up this file while backing up the iTunes media folder, re-installing iTunes, and then open it, so that your database is also recovered, the advantage is that the reinstalled iTunes won't require a full re-synchronization with the iPhone, because the database is still the same.
Sometimes, you have installed a later version of iTunes. After using it, you can uninstall it and install it back to a later version. In this case, you may see "file cannot be read" iTunes. library. because it is created by more advanced iTunes, You can manually find the file and delete it. re-open iTunes to automatically create a new one for you, you can use iTunes normally, but your database information will be lost. If the file cannot be deleted, you can create a new database by using the method described above.

3. Can I manually ask iTunes to save the database content to the iTunes media folder?
Of course you can. If you have not selected "Copy files to the iTunes media folder when adding a resource" as described above, you should use this function on a regular basis. Select "Sort databases" in the "file/Database" menu, select "unified files", and click OK, as shown in:

It is worth noting that if you have installed multiple versions of the same software on a regular basis, you can save previous versions.
4. During synchronization, the system prompts that all information will be erased. How can this problem be solved?
Many people may encounter this situation, most of the time because they have changed their computers or reinstalled their systems. But the iPhone is full of all kinds of music and programs. In fact, the reason is very simple, because your current iTunes database is inconsistent with the iPhone, which has been mentioned above, iTunes library. ITL is lost after the system is reinstalled, and a new file is automatically created in the new iTunes. You should think of a solution now.
The main purpose of this article is to remind you of the following special points:
A) if you choose to erase all the data, pay attention to the difference between the database and backup described above. You can recover the backup content such as your short message through backup. Remember.
B) since you will install many happy versions of IPA, or use cydia to install the Deb program, or 91 to install the pxl program, in this case, if you synchronize, all the programs mentioned above will be retained, but the order will change. So don't worry.
C) What if I bought an app in iTunes. At this time, synchronization will affect such applications, but you can transfer the purchased app back to the iTunes database before synchronization. You can right-click the iPhone on the device, select the transmission purchase item and then synchronize it. For details, see:

5. Can I export the iPhone materials, such as music, back to the database? Again, we recommend a powerful software called xilisoft iPod rip.
This software supports Chinese native and has very simple functions. It can export music, photos, and videos from the iPhone to the iTunes fund or PC. You must install iTunes before using it.
In addition, this software allows you to directly import music, photos, and videos to the iPhone from a PC. The most important thing is that this tool can be used without jailbreak.
