Limitations and Considerations with CrashPlan PROe

Appropriate use

CrashPlan PROe is meant to protect laptops and desktops over any internet connection, for faculty and staff within the Clark School of Engineering and the College of Mathematics and Natural Science. The CrashPlan PROe backup is intended to provide a measure of security when files are accidentally deleted, a hardware component fails, or a computer is lost or stolen.


Computers on campus will be able to take advantage of fast internet networking for superior performance; whereas home users, with slow internet upload speeds will see reduced performance.

For optimal results, during the initial backup it is best to use a wired, Ethernet connection and prevent your computer from going to sleep.

CrashPlan PROe will perform best with computers having less than 2 TB of data or several million files. Actual performance will vary depending on network throughput, the amount of physical RAM, disk speeds, and CPU capability. Please review this support article if CrashPlan PROe is running out of memory and crashing due to large file systems.

Other considerations

Users should not use cellular data networks i.e. “tethering” for network connectivity in conjunction with CrashPlan PROe. Avoid this combination to prevent incurring costly data plan overages. Consult the CrashPlan PROe network configuration documentation to learn how to adjust client network settings.

Archives are encrypted using an algorithm based on a person's LDAP credentials and cannot be transferred to another user. 

Never back up virtual machine files created on your computer using applications like VMware Fusion or Parallels. Instead, install CrashPlan PROe inside the virtual machine itself.
