Who is this article for?
CrashPlan for Small Business, yes.
Code42 for Enterprise, yes.
Link: Product plans and features.
Overview
The amount of available memory needed to use the Code42 app increases with the size of your archive or backup file selection. If your Code42 app crashes frequently, you may benefit from increasing the available memory (or adjusting backup settings to require less memory) if the following conditions apply:
- Your Mac or Linux device's backup selection exceeds 1 TB of storage or 1 million files.
- Your Windows device's backup selection exceeds 4 TB of storage or 4 million files.
Considerations
This article assumes you have the ability to edit your backup settings. Your administrator may prevent editing of these settings.
Additional memory considerations:
Recommended solution
You can increase the amount of memory available to the Code42 app using command-line interface (CLI) commands.
You shouldn't need to increase memory unless you are experiencing frequent crashes of the Code42 app and your backup files exceed 1 TB of storage or 1 million files on Mac or Linux or exceed 4 TB of storage or 4 million files on Windows. If you have questions about whether adjusting memory may help resolve crashes of the Code42 app, contact our Customer Champions .
Video
Watch the brief video below for instructions on increasing the amount of memory available to the Code42 app.
Although this video demonstrates how to increase memory allocation using CrashPlan for Small Business, the same process applies to Code42 for Enterprise.
Alternative solution
The Code42 app only uses the maximum memory allotted if it is needed. However, if the maximum memory supported by your device does not accommodate the size of your backup file selection, there are several alternative ways to reduce memory usage.
Remove system and application files from your backup selection
The Code42 app is designed to back up user files (photos, documents, etc.). It is not designed to back up your operating system or application files. When system and application files are included in your backup file selection, the Code42 app uses more resources, like memory, backing up these files. Review our guidelines for choosing what to back up for more information.
Reduce backup frequency
The Code42 app monitors changes to files in real time based on your backup frequency and versions settings. More frequent backups or large numbers of files require the Code42 app to use more system resources to process your backup. You can reduce the frequency of the New Versions scan to conserve memory.
Reduce CPU allocated to the Code42 app
You can control the amount of CPU processing time the Code42 app is allowed to use both when you are present (working on your device) and away. Most modern devices can support allowing the Code42 app to use a high percentage of CPU time without experiencing any performance issues, but you may want to adjust these settings for older devices. You can adjust these settings from the Code42 app.
- Sign in to the Code42 app.
- Navigate to Device Preferences:
- Click Usage.
- Reduce the percent of time CPU is allowed to use when the user is both away and present.
Schedule backup
Finally, if you are still experiencing performance issues related to memory, you can configure the Code42 app to back up only at specified times. However, be careful to set a schedule that allows the Code42 app to run while your device is on and not in standby mode. You can adjust your backup schedule from the Code42 app.
- Sign in to the Code42 app.
- Navigate to Backup Set Settings.
- Next to Backup Schedule, click Change.
- Select Only run between specified times.
- Select the days and hours when the Code42 app is allowed to back up.
- Click Save.
Reduce your file selection
If you experience issues related to the Code42 app's memory usage after adjusting the settings described above, you may need to remove files from your selection to reduce the amount of memory needed to run the Code42 app.
Deselecting files from your backup file selection permanently deletes them from your backup archive. You cannot download files that have been removed from your backup file selection.
