In many cases, the Code42 app's default memory setting supports backing up as much as 1 TB (1,024 GB) of data or as many as 1 million files. However, you may need to assign additional system memory if the Code42 app:
- Does not open when launched
- Opens, but displays the message: Code42 CrashPlan cannot connect to its background service
- Closes abruptly while backing up files
This article describes how to diagnose and fix the problem on a 64-bit system to resume successful backups.
