Hi,

This Error can be caused by a multitude of things. Here are some of the basics

1. The drive had alot of disk activity, so df2k (our driver) was unable to freeze the drive.

2. antivirus was running a scheduled scan during the time of backup.

3. there is other backup software on the system, and there is a driver conflict.

4. There might be an issue with the hardware, please run chkdsk /r

If you are still having issues, please contact our support team @ 425-644-6000 or at support@ultrabac.com

Thanks!

Another common cause for this is (on a brand new installation) is to forget to reboot the server prior to the backup. During install, a boot-time driver called DF2K is installed (this is the driver that lets UB freeze the volumes) and the reboot allows the driver to activate. I think though that the error message in this case specifically states this, so I doubt that this is your particular problem.

Another increasingly common cause for this problem is when attempting to freeze large partitions (eg 500GB+) which have very small allocation-unit (cluster) size (eg 512byte). The design of DF2K requires a large amount of "non paged pool" which is a limited resource, and the large size/small-clusters can cause DF2K to need more than is available. Future versions of UB (8.3) will utilize a completely new driver architecture called UBFD that drastically reduce the amount of non-paged pool required during freeze.
