Windows 7 Understanding the Importance of C:\Boot\BCD and C:\Boot\BCD.log in Windows XP Backup

[seekermeister]

I'm in the process of testing PCClone EX Lite, that came bundled with my docking station on W7, but what I'm more interested in is using it on XP, because I don't want the expense of buying another license for True Image for it.

During the backup, it lists a number failed operations, either because the files were already in use or because of access being denied. I suppose that could be worked around by backing up the drive when it isn't in use, but that's not practical on my XP machine, because it is only single boot.

Not sure how it applies to XP at the moment, but the two failures that I'm most curious about are for C:\Boot\BCD and C:Boot\BCD.log. Even though my desktop is a multi-boot system, and I always install OSs with all other drives disconnected, so there is no boot screen involved, other than the BIOS Boot Menu, I'm wondering just how essential those two files are to what in essence is a single boot machine?

The files "C:\Boot\BCD" and "C:\Boot\BCD.log" are essential system files related to the boot configuration in Windows operating systems. Here's a breakdown of their importance and how they relate to your single boot XP machine:

1. Boot Configuration Data (BCD):
   • The BCD file contains boot configuration parameters and controls the operating system's startup process.
   • In a multi-boot system, the BCD file is crucial because it stores information about each installed operating system on the machine.
   • Even in a single boot setup, the BCD file is still critical for the proper functioning of the Windows operating system.
   []BCD.log:
   • The BCD.log file is a log file that tracks changes to the Boot Configuration Data store.
   • It records changes made to the BCD store, providing a history of modifications.
   • It can be helpful for troubleshooting boot-related issues.

     Importance in a Single Boot System:​

     In a single boot XP machine scenario, these files are still important for the following reasons:
     • System Integrity: The BCD file is crucial for the system's overall integrity during the boot process.
     • Error Recovery: Both files aid in error recovery and troubleshooting boot-related issues.
     • Backup Considerations: While backing up these files may encounter errors due to their in-use status, finding a way to include them in your backup routine is advisable for system recovery purposes.

     Recommendations:​

   []Backup Strategy:
   • Try to back up these files when the system is not actively using them. This might involve scheduling backups during system idle times or using backup software that can handle in-use files effectively.
2. Monitoring Changes:
   • Keep an eye on changes to these files, especially if you encounter boot issues in the future. The BCD.log can provide insights into modifications that could impact the system's boot process.

     Testing PCClone EX Lite on Windows XP:​

     As you are testing PCClone EX Lite on Windows XP, consider the following points:
     • Compatibility: Ensure that the backup software is compatible with Windows XP and can handle system files effectively.
     • Backup Verification: After running backups, verify that critical system files like the BCD and BCD.log are included and accessible in the backup sets.

Given the critical role of these files in the boot process and system integrity, it's recommended to address any backup failures related to them to ensure a robust backup solution for your XP machine.
