If you have a large amount of data to back up the cloud, you may notice that CrashPlan is uploading files slower than you expect, even if you have plenty of bandwidth. As a general estimate, CrashPlan users can expect to back up about 10-30 GB of information per day on average if their computer is powered on and not in standby mode. We are a shared service, which means that upload and download speeds depend on the number of users connected at any given point. CrashPlan estimates the total time that it will take to upload your data based on your current network speeds. This estimation will fluctuate over the time of your initial backup.
There are several things you can adjust to complete your initial backup sooner:
- Refine your file selection
- Increase CPU percentage available for CrashPlan to use.
- Prevent your computer from going to sleep so that CrashPlan can work all day and night.
- Extend the default backup frequency time
Refine your file selection
If you select your entire hard drive, including system and application files, CrashPlan may not back up your personal files efficiently. Your computer creates new system and application files frequently, which are small. Because CrashPlan prioritizes its to-do list based on file size and creation date, this data is backed up before other files in your backup selection.
Increase CPU available to CrashPlan
CrashPlan requires system resources to encrypt, compress, and de-duplicate your files before sending. You can increase the amount of CPU CrashPlan can dedicate to these activities, which will usually improve the speeds CrashPlan can upload at.

Prevent your computer from going to sleep
CrashPlan doesn’t run and can't upload data if your computer is asleep or turned off. CrashPlan only runs when the computer is on and the hard drive is powered on. Check your system settings to ensure your device is not regularly going to sleep and interrupting backups.
Extend the default backup frequency time
CrashPlan assumes that what you're working on now is most important so prioritizes your most recently changed files and backs them up first.
The default setting is to back up new information every 15 minutes. This offers great protection for backing up your files right away and allows you to easily revert to a previous version of a file. However, it also means that CrashPlan uses some resources to back up frequent versions of your files as you work.
Extending the default backup frequency time allows CrashPlan to work through your files without the the additional workload of backing up multiple versions of your files. The trade off to extending the backup frequency time is that your new files and changes won't be backed up as quickly. To change this setting:
