Method 2;-

Go to CrashPlan configuration directory in Linux : /usr/local/crashplan/conf/ (sorry for the Windows and Mac users)

Open my.service.xml file and find the following lines.

  • <dataDeDupAutoMaxFileSize>1073741824</dataDeDupAutoMaxFileSize>
  • <dataDeDupAutoMaxFileSizeForWan>0</dataDeDupAutoMaxFileSizeForWan>

0 is a meta value which refer unlimited.

Change it to 1.


Then restart CrashPlan engine (/etc/init.d/crashplan).

It will decrease high CPU usage and increase upload speed.

Note : If you face any issue, change the value back to 0.
