Designed to make minimal demands on your computer's resources, CrashPlan's default settings favor quiet, background operation over outright speed. There are times, however, such as during your initial backup or after adding a large number of files to your backup selection, when you may decide speed is more important.
This article outlines some temporary adjustments that allow backups to be completed more quickly, as well as some items to consider before changing any settings.
If you are experiencing upload speeds that are slower than you expect, there are several things you can adjust in the CrashPlan app to attempt to improve upload speeds. By default, CrashPlan has limits in place to prevent it from using too many system resources. Changing these settings to increase the system resources available to CrashPlan can help speed up your backup.
CrashPlan assumes that what you're working on now is most important so prioritizes your most recently changed files and backs them up first.
For CrashPlan for Home subscribers, 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 increase the time between backups:
Advanced users only: Increase the sending message buffer size. Do not adjust the message buffer size if you are on a WAN.
