There are some default rules including size that decide the files that will be considered for the Continuous Data Protection operation. To minimize the impact of CDP on your normal PC functions at regular hours, the operation is executed only for files less than 500 MB. This usually covers most office and other documents that you work on during the day. The remaining files (in the Backup set) are considered during the normal Scheduled / Interactive backups. Temporary files, system files and mapped drives are excluded from the Continuous Data Protection operation.
Please forward us the logs using "send error report" option in the application. Our Tier 2 technical support team will review the logs and will contact you with an update.
