Restore Points

This function is available in the Restore Points dialog box which is invoked by clicking the Restore Points button in the Cool Tools tab of the main window.

Every time you perform a clone operation (in any of the four operation modes: /backup1, /backup2, /backup3, /backup0), XXCLONE saves the current state of the system registry as a Restore Point (in %SystemRoot%\xxclone.arc\ in the Source volume itself).  Each Restore Point is represented by a directory with a date-encoded name.

This dialog box provides two distinct functions that are related to the Restore Points.

      1. Setting the retaining schedule of restore points.
      2. Performing a system restore operation from a restore point.

Restore Points Retaining Schedule

  • In order to keep the consumption of the disk space by Restore Points within a reasonable limit, XXCLONE trims the number of Restore Points according to a retaining schedule settable by the user.

    The retaining schedule classifies the collection of Restore Points into four series (Daily, Weekly, Monthly, and Yearly) with four corresponding parameters that set the maximum number of Restore Points to retain in each category.

  • For example, the default setting (7 days, 4 weeks, 12 months, and 5 years) maintains 7 daily restore points, 4 weekly restore points, and so on.  A daily restore point that has become 8 or more days old will be automatically reclassified into the weekly series.  A 5-week old one in the weekly series will also re-classified into the monthly series, and so forth.
  • For most users, the default settings should strike a good balance of the availability of the restore points for recent days and the storage requirement for older data.
  • When two or more clone operations are made in one day, all of the restore points of the day will be kept until midnight.  When multiple restore points from a previous day are found, XXCLONE will discard all but the newest one in the group.
  • When you modify the restore point schedule, the change will be effective at the next clone operation.

System Restore Operation

  • The system restore operation using a restore point is carried out by first highlighting a restore point of choice and then clicking the Restore Target Registry Now button.  A system restore operation consists of retrieving the system registry files from the specified restore point directory in the Source and copying them into the proper locations in the Target volume.  No other files will be restored since that is not within the scope of the Restore Point design.
  • A volume-wide restoration for a given volume can only be achieved by cloning the volume from its backup volume (using XXCLONE's clone feature).  You may also copy files or directories from a cloned volume manually using any appropriate tool as needed.
  • The list of the restore points shown in the box are those available in the Source Volume selected immediately before you entered in the dialog box. Similarly, the target of the restore operation is the Target volume you selected immediately before you entered the dialog box.  Unlike the cloning operation, for the system restore operation, you may choose the current system volume (typically C:) both as the Source volume and the Target volume at the same time.  In fact, we recommend it as the preferred choice.
  • When you complete a system restore operation with the current Windows system volume as the Target, then, the effect of the restoration will become effective after the next reboot.  We strongly suggest that you perform a system reboot immediately after the current system volume is restored.  On the other hand, if a system restore is performed on a Target volume other than the current windows system volume, then, no further action (nor a reboot) will be necessary.
  • Since the contents of the Source volume is typically backed up into the Target volume in the course of a periodic backup, the restore points data for a given volume is stored both in the originating volume itself and its backup (clone target) volume.  Although you will find restore points for a given volume in its cloned volume, we suggest that you restore the registry of Volume X: from the restore points archived in itself (also Volume X:) in principle. But, if the restore points in the volume itself is either absent, corrupted, or having trouble in restore operation, then, you may use an alternate copy saved in another volume.
  • In short, the System Restore function is quite flexible as to the choice of the Source and the Target volumes. 

    For example, you may use this feature to even repair a volume on a USB-attached disk that belongs to another computer (e.g, with a serious boot problem) by restoring its system registry from one of the restore points saved on itself.

    Howerver, it will be the user's responsibility to make sure that the restore point selected in the Source indeed corresponds to the Target volume when you are dealing with a volume that belongs to a computer other than the current host computer.
