Writes to a storage device of a protected computer system are tracked in a manner that accounts for those writes that may occur during a system reboot process when the file system is not available. During the shutdown process, write tracking data is maintained in system memory and is written into storage locations allocated to the tracking file after the file system has been dismounted so that any writes that may occur during the file system dismount can be captured. During the boot process, temporary write tracking data is maintained in system memory even before the file system is mounted so that any writes that may occur immediately after the file system mount can be captured. The temporary write tracking data is later merged with the tracking data contained in the tracking file and the merged tracking data is used to track further writes to the storage device.
In a computer system having a processing unit, system memory, and a storage device, the computer system being configured with a file system and a bitmap driver for tracking writes to the storage device by updating tracking data stored in the system memory, a method of tracking writes to the storage device during a shutdown process of the computer system which includes dismounting of the file system, said method comprising:
