Problem
When the Actifile agent is running, your computer experiences significant slowdowns due to 100% processor usage, particularly by OneDrive, SharePoint, or Dropbox. You might notice these apps continuously syncing files even when you’re not actively accessing them.
Root Cause
When OneDrive, SharePoint, or Dropbox is set to Always decrypt in Actifile’s Decryption Allowlist (formerly Application Whitelist), it can result in an encrypt-decrypt loop.
Here’s how it happens:
- A cloud app initiates a sync for a file.
- Actifile decrypts the file, which is uploaded to the cloud app.
- Actifile re-encrypts the file.
- The re-encryption triggers another sync by the cloud app.
This repetitive loop consumes system resources and causes high CPU usage.
Solution
To resolve this issue, ensure that desktop-synced cloud applications like OneDrive, SharePoint, or Dropbox are not set to Always decrypt in your Decryption Allowlist. The default value for these applications is Keep Encrypted.
If Decrypted Access Is Required:
Agent version 105 and earlier:
Step 1. Log in to app.actifile.com and head to Deployment > Policies > Classifiers > Add.
Step 2. Select the classification type by file source or by folder to identify the cloud-synced files requiring decrypted access.
Step 3. Set encryption to disabled, check the Override other rules box and save the new classifier.
Agent version 106 and later:
Step 1. Log in to my.actifile.com and head to Deployment > Classifiers > Add New.
Step 2. Create a classifier based on a storage platform or folder to identify the cloud-synced files requiring decrypted access.
Step 3. Once the classifier is created, click its name to open its settings.
Step 4. Navigate to the Actions screen and find the Manage Encryption section. Keep the Encrypt Data box unchecked and select Override other classifiers' encryption settings.
The selected cloud application will now access the decrypted version of your sensitive files.
