Proper CrashPlan Memory Allocation

Below are the instructions for allocating additional memory for CrashPlan Clients. This becomes necessary as the client is expected to backup larger datasets. This holds true for all versions of the client (Plus, PRO, PROe). Please reference the chart below for the values you should be setting.

+--------------------------------+
|  BACKUP SIZE  |  RAM REQUIRED  |
|---------------|----------------|
|    <=500 GB   |      512 MB    |
|---------------|----------------|
|   .5-1 TB     |      768 MB    |
|---------------|----------------|
|    1-3 TB     |     1024 MB    |
|---------------|----------------|
|    3-5 TB     |     2048 MB    |
|---------------|----------------|
|    >=5 TB     |     2560 MB    |
+---------------|----------------+

1.  Stop the backup engine by typing this into the Terminal application:

sudo launchctl unload /Library/LaunchDaemons/com.crashplan.engine.plist
2.  Run this command to edit the backup engine:
sudo nano /Library/LaunchDaemons/com.crashplan.engine.plist

3.  In /Library/LaunchDaemons/com.crashplan.engine.plist, find this line:

-Xmx512m
4.  Edit that line to something larger (the value from the chart above) E.g.:
-Xmx1024m
5.  Hold the Control key and tap the x key to exit. Choose “y” to confirm it.

 

6.  You’ll see the prompt “File Name to Write.” Hit enter to save to the existing location.

 

7.  Start the backup engine by typing:
sudo launchctl load /Library/LaunchDaemons/com.crashplan.engine.plist
