Incremental Backup of BFS File Spaces

When performing an incremental backup, CA VM:Backup determines whether changes have occurred since a previous backup by computing a special hash value based on the timestamp values for data changes and file attribute changes. CA VM:Backup computes this hash value regardless of the type of change detection the system administrator specifies in the backup job template file.
