Adjusting Memory Allocation to Code42 CrashPlan

Adjusting the memory allocation

Code42 CrashPlan (formerly CrashPlan PROe) might run out of memory and crash when de-duplicating and backing up large file systems greater than 1TB or one million files. You can experiment raising maximum amount of of RAM that CrashPlan can use to prevent incomplete backups. 

Step 1: Launch the Code42 CrashPlan application.

Windows 7

At the start menu, go to the Search box and begin typing “crash…"  The system will bring up the shortcut to the CrashPlan PROe application.  Click it.

Windows 10

At the start menu, go to the Search box and begin typing “crash…" The system will bring up the shortcut to the CrashPlan PROe application. Click it.
 

OS X

Navigate the Finder to the Applications folder and double-click the CrashPlan icon.

Step 2: Launch the command line interpreter.

Double click the building icon on the top right-hand side (authentication is not necessary.)

A command line interpreter window appears. In this example, we're allowing CrashPlan to use a maximum of 1.5 GB (1536 MB) of RAM. Type the following command and press ENTER.

CrashPlan won't use all this memory all the time. This is the ceiling of how much it can use when performing certain tasks. For most users, the default 1024 MB ceiling strikes the right balance. For exceptionally large amounts of data, experiment with different values based on how much physical RAM your computer has or how many  applications you run simultaneously. Importantly, only use increments like 1024, 1280, 1536, 2048, 2560.
