Considerations and Limitations when using CrashPlan for backup at UMD.
Most computers on campus will take advantage of Internet2 networking for enhanced performance. Home users with slow internet upload speeds will find reduced performance. For best results, especially during the initial backup, use a wired network connection and temporarily prevent your computer from falling asleep.
As a general rule, CrashPlan may not perform as expected on computers with more than 1 TB data or several million files. Actual performance depends on the amount of physical RAM, network throughput, disk speeds, CPU efficiency, and other factors. Review this support article if CrashPlan is running out of memory and crashing due to large file systems.
Users who depend on cellular data networks (“tethering”) for network connectivity should configure CrashPlan to avoid using their mobile hotspot to avoid costly plan overages. See CrashPlan network configuration documentation to learn how to adjust client network settings.
Microsoft Outlook users must take extra precautions to make sure their data is properly protected. CrashPlan has separate support articles for backup and restore.
Special considerations should be taken when backing up certain types of open files, like databases. See CrashPlan support documentation for more information.
Do not back up virtual machine files created on your computer using applications like VMware Fusion or Parallels. Instead, install CrashPlan inside the virtual machine itself.
