Reassigning Cache Folder To A Different Directory

  • CrashPlan for Home
Need enterprise or small business documentation?
This article is intended for CrashPlan for Home users. For Code42 CrashPlan and CrashPlan PRO documentation, read this page on our enterprise support site.

Overview

CrashPlan stores a cache of temporary information on your computer, including information about your destinations, the data you have on your computer, and a number of settings that help CrashPlan run fast. If your cache becomes large, we recommend clearing it to resolve the issue.

Alternatively, you can move the cache to a drive with more storage as described in this article; however, please note that this is an unsupported process.

Unsupported Process
The information presented here is intended to offer information to advanced users. However, Code42 does not design or test products for the use described here. This information is presented because of user requests.

Our Customer Champions cannot assist you with unsupported processes, so you assume all risk of unintended behavior. You may want to search our support forum for information from other users.

Recommended solution

  1. Stop the CrashPlan service
  2. Find my.service.xml
    If you used the default install location, then the file is located in the following directory:
    • Windows Vista, 7, 8, 10, Server 2008, and Server 2012: C:\ProgramData\CrashPlan\conf
      To view this hidden folder, open a file browser and paste the path in the address bar. If you installed per user, see the file and folder hierarchy for file locations.
    • Windows XP: C:\Documents and Settings\All Users\Application Data\CrashPlan\conf
      To view this hidden folder, open a file browser and paste the path in the address bar. If you installed per user, see the file and folder hierarchy for file locations.
    • OS X: /Library/Application Support/CrashPlan/conf/
      If you installed per user, see the file and folder hierarchy for file locations.
    • Linux: /usr/local/crashplan/conf
  3. Open the file in a text editor as an administrator (Windows) or with an editor that has root permissions (Mac)
    See External Resources for more information
  4. Find the line enclosed by <cachePath>...</cachePath>
  5. Change the file path inside the <cachePath> section to the file path where you want to move the cache
    For example: D:\Programs\CacheStorage
  6. Save the changes
  7. Restart the CrashPlan service
  8. Navigate to the appropriate directory below and delete the cache folder:
    • Windows Vista, 7, 8, 10, Server 2008, and Server 2012: C:\ProgramData\CrashPlan\cache
      To view this hidden folder, open a file browser and paste the path in the address bar. If you installed per user, see the file and folder hierarchy for file locations.
    • Windows XP: C:\Documents and Settings\All Users\Application Data\CrashPlan\cache
      To view this hidden folder, open a file browser and paste the path in the address bar. If you installed per user, see the file and folder hierarchy for file locations.
    • OS X: /Library/Caches/CrashPlan
      If you installed per user, see the file and folder hierarchy.
    • Linux: /usr/local/crashplan/cache

Deleting the cache does not impact the data stored in your backups or change your settings. CrashPlan will rebuild your cache in the new location.

Alternative solution

Alternatively, if you are comfortable with creating soft links (also know as symbolic links or symlinks), you can use a soft link to redirect data from the original cache folder to an alternative location.
