Does Smart Cache Work in Offline Mode and Service its Users if it is not Connected to Cloud?
Smart Cache can operate even when it loses network connection with the cloud. Desktop App users can continue to open and modify files on the Smart Cache device and all their file operations will get saved. Smart Cache in Offline Mode serves lock requests locally so that it allows only one user to modify a file at a time. File and folder modifications are synchronized with the cloud when network connectivity to the cloud is restored. This option is only applicable for folders served by Sync, but not for folders served by Cache.
Smart Cache supports up to 7 days of offline access for end users connected through the Desktop App.
Can I Use Smart Cache as a Migration Tool to Move Data from On-Premise Servers to the Cloud?
No, we don’t recommend using Smart Cache as a migration tool; instead, try out the Egnyte Migration App.
Do I Need a Special License for Smart Cache?
Yes, Smart Cache requires a hybrid license. To verify if your plan includes it, navigate to the Plan Details page under Settings where it will be listed as 'Smart Cache or Storage Sync'. If the plan does not include this license, contact the Egnyte Sales Team or your Account Manager for assistance.
How Do I Purchase Smart Cache?
Some plans include a hybrid license. It will be listed as Smart Cache or Storage sync in the Plan Details page under Settings. If this option is not available, contact the Egnyte Sales Team or your Account Manager for assistance.
How Do I Deploy And Enable Smart Cache?
To deploy Smart Cache, ensure the required hardware is available in your network. For guidance on setting up the Smart Cache device, refer to the instructions provided in the Smart Cache Setup and Configuration Overview article.
To enable Smart Cache in the Egnyte domain:
1. Log in to the WebUI and click on Settings.
2. Click on Configuration and then on Applications.
3. Enable the option Allow users to access folders stored on Smart Cache device.

How Do I Determine The Right Size For The Data Disk?
IT administrators are recommended to determine: -
- The amount of data that users are expected to access and
- The amount of new data that users are expected to create over a period of 90 days.
Smart Cache will retain both accessed and new data for a minimum of 14 days. However, the duration of data retention in the cache may vary in the future, necessitating a reassessment of disk size requirements. Additionally, Smart Cache requires storage for caching metadata and internal operations. We recommend provisioning double the estimated storage mentioned above to ensure optimal performance.
Sizing the disk is an extremely important consideration for Smart Cache. Provisioning a disk that is too small can lead to aggressive eviction of data from the cache and may result in occasional sync failures and errors.
The 2x recommendation is over and above any storage needed for folders that may have been selected for synchronization.
Are There Any Policies Available For Smart Cache?
As of now, there are two user-defined policies available for Smart Cache:
- Storage policy
- Persistence policy.
Users get more information under the section Set Up Custom Policies in the product guide.
Smart Cache manages data eviction and storage optimization based on the frequency of data being accessed and the least recently used principle.
Can I Pin Folders with Smart Cache?
This functionality is not yet available in Smart Cache's Cache warming feature. However, it can be achieved through the Folder Synchronization feature, where the user can select the folder(s), and it always stays on the disk and is never evicted.
Does Smart Cache Support Offline Mode?
Smart Cache supports offline mode through Desktop App collaboration mode and all synced files will be available when the device is offline. However, if certain folders need to be available in offline mode, users can select them for syncing(Refer to Folder Synchronization for Offline access section in the product guide).
How do I check the status of the Smart Cache Device?
For Smart Cache devices, the cloud device dashboard settings should show the device status as Healthy, as shown in the screenshot below.
How Many Users Does Smart Cache Support?
Currently, Smart Cache supports up to 300 users on a single device.
How Do I Add More Users to a Smart Cache Device?
Adding users to use a particular device can be done by creating the user in the Web UI and adding it to a group associated with that device. Refer to the Product Guide for more details on the steps to create and attach the group to the Smart Cache device.
How Do I Shutdown or Restart the Smart Cache Device?
Smart Cache can be shut down and restarted from the console by selecting specific options.
For instructions on how to perform these operations, refer to the Shutdown or Reboot Smart Cache Device section in the Product Guide.
How Does the Egnyte Desktop App Decide Which Smart Cache Device to Connect With?
Egnyte Desktop App uses an auto-discovery mechanism to look for all Smart Cache devices in the network that the user has permissions for, compares the latency to each device, and identifies the optimal Smart Cache device to connect.
Listed below is a high-level sequence of steps of the discovery process:
- Get a list of all Smart Cache devices in the domain.
- Check which Smart Cache device the user is authorized to connect.
- Check if those Smart Cache devices are healthy.
- Compare the latency between the cloud and healthy Smart Cache devices.
- Connect to the optimal device (or fall back to the cloud connection if it can’t connect).
Will Users Lose Access to the Shared Folders if a Smart Cache Device Fails?
Smart Cache uses the Egnyte Desktop App as a single interface for users, so if a device fails, the Desktop App automatically identifies this and services all requests directly to the cloud without any user impact.
However, if the Smart Cache device fails to connect to the cloud in scenarios where the network connectivity is disrupted between the Smart Cache and the cloud, Desktop App users remain connected to the Smart Cache device in offline mode.
How can I modify The Enhanced Security Feature Settings (SMB Signing Or Encryption) that are available in SMB Collaboration Mode?
Enhanced security feature settings (SMB signing or encryption) are only available during Smart Cache installation, and the only way to modify those options is to factory reset the device from the Smart Cache command prompt. Refer to the section Reset Configuration or Perform Factory Reset in the product guide for more information. Contact the support team for assistance, as it requires root access.
