1. Which versions of Windows have system recovery features? Windows Me and Windows XP (Home Edition and Professional Edition). The following questions and answers are mainly for Windows XP.
2. What is the difference between system recovery and file backup?
System recovery only monitors a set of core system files and certain types of application files (such as files with suffix exe or dll), records these files before the change The backup tool is used to back up the user's personal data files, ensuring that a secure copy is stored on a local disk or other media. System Recovery does not monitor or restore changes made to personal data files (for example, documents, graphics, emails, etc.). The system data contained in the restore point of the system recovery can only be restored over a period of time, and the backup made by the backup tool can be restored at any time.
3. Does the system need to be turned on by the user?
No. Windows XP system recovery is automatically turned on, but at least 200M of available hard disk space is required. If the hard disk does not have 200M free space, the system recovery will be automatically disabled, and will be automatically turned on once there is enough space. By default, the system restores up to 12% of the hard disk space, and its "automatic restore point space management" will clear the oldest restore point, free up space and maintain the rolling security of the system recovery.
4. Will system recovery reduce system performance?
No. System recovery does not significantly affect system performance when monitoring system operating conditions. Creating restore points is a very fast process and usually takes only a few seconds. Regular system status checks (default is every 24 hours) are also only performed during system idle time without interfering with the operation of any user program.
5. Who has the right to use system recovery?
Only users with administrator privileges can use system recovery to restore past system status, or adjust system recovery parameter settings. However, the creation of a restore point is not related to whether the administrator is logged in. For example, when a non-administrator's other user uses the machine, System Recovery will still create a system checkpoint and an event-driven checkpoint, but the user cannot use the restore function, and only users with administrator privileges have the right to restore the machine state.
6. Does the system restore and protect user personal data files such as Word documents and emails?
No. System recovery does not monitor changes to user personal data files such as documents, graphics, emails, etc., and therefore cannot restore these files.
7. System recovery monitoring which files?
System recovery only monitors a set of core system files and certain types of application files (such as file suffixes exe and dll, etc.), record the status of these files before the system changes . For a list of all protected file types, see "Monitored File Suffixes" in the Recovery section of the Platform SDK.
8. How does the system recover passwords?
Passwords that are not restored:
1) Windows XP password and password problems are not restored. This is to prevent the restore point from including an old password that the user has not remembered, thereby causing confusion and inconvenience to the user.
2) IE and Content Advisor password and password problems are not restored. The reason is the same as above.
Recovered password:
1) Restore web server-based application passwords such as Windows Messenger, AOL Messenger, QQ, etc. Restoring these old passwords will not bother the user, because only the password backup is stored in the machine, and the actual password is stored in the web server. System recovery simply restores the old password stored locally by the application without actually changing the program password. The user still needs to log in to the server with the current password.
2) Domain and host passwords are similar to the above. Once the host reconnects with the domain, the old password in the cache is upgraded to the current password.
9. If the system recovery is automatically uninstalled before reverting to an application installation,
System Recovery will not completely uninstall the application. Because system recovery only monitors and restores changes to specific types of files, such as system file changes caused by installing the program, etc., if you want to completely remove all changes caused by installing an application and completely uninstall the application, the user first needs Use the Add or Remove Programs option in Control Panel to remove the program. What the system restores is to restore the system changes caused by the installation, including:
1) Delete the monitored files added during installation
2) Restore the changes of the monitored system files
3) Restore Registry (Note: retain some of the registry current value)
4) Installation of added or modified non-monitored files and other files are not recoverable, will not be deleted, such as will not delete the application's new graphics file and Text files will not be restored to existing ones.
10. Why do some downloaded executables be deleted when recovering?
If the downloaded file suffix belongs to the monitored file type, then these files will be lost if the restore point is downloaded. If you don't want to lose these files, you can move them to the My Documents folder or other unmonitored hard drive area. In case the useful download files are deleted during recovery, you can also re-acquire these files by undoing this recovery.
11. When will the restore point be created?
The user can manually create a restore point at any time using the system recovery wizard. In addition, the system will automatically create a restore point under the following conditions:
1) Install the device driver
2) Install the application with Windows Installer, or Install ShIEld Pro 7.0 and above
3) Use automatic Upgrade for Windows XP upgrade
4) Perform system recovery operation (when performing system recovery operation, restore point will also be created, so users can cancel this recovery process if necessary)
5) Use backup tool to backup from backup Recovering data in media
6) Creating a daily restore point every 24 hours
12. Can I keep a permanent restore point?
No. This feature is not supported by current system recovery systems. Each restore point only saves system changes since the last restore point was created, which minimizes space usage and improves performance. All restore points are related to each other. Therefore, to restore the machine from its current state to a previous state, all restore point records between the two restore points are required. For example, when a user attempts to restore the machine state from point D to point A, system recovery requires the use of all change records for points C, B, and A.
If you want to set a restore point as a permanent restore point, you need to spend a lot of space to store the entire restore point chain. For now, this is very unrealistic. System Recovery has an "automatic restore point space management" function that automatically clears the oldest restore point and frees up the occupied space. By default, restore points have a retention time of up to 90 days.
13. How much hard disk space does the system need to recover?
1) Hard disk larger than 4G, by default, the system recovers 12% of the hard disk space
2) Less than 4G hard disk, by default, System recovery only takes up 400M space
3) Users can adjust the space for system recovery at any time.
