Connecting to IDrive® e2 with HybridMount
- Go to QNAP App center and install HybridMount.
- Launch the HybridMount application.

- Click Create Remote Mount and click Create File Cloud Gateway.

- Select S3 Compatible from Cloud service drop-down, input the access keys and endpoints, then click Next.

- Create a cache space: Select the pool, specify the volume capacity and click Create.

- Once the HybridMount file cloud gateway is created, you can manage your data on IDrive® e2 from QTS File Station or using your computer after mounting the NAS as a network drive.

Note: If you receive an error while configuring S3 Compatible storage in QNAP HBS 3, specify the server address in the format <endpoint>:443 (for example, s3.us-east-1.idrivee2.com:443). This is currently required due to a known issue in QNAP HBS 3, which requires the HTTPS port (443) to be explicitly specified.
Due to this issue, using Signature Version 4 (v4) may result in an "Authentication error. Cannot connect to cloud service."
As a temporary workaround, configure the connection using Signature Version 2 (v2).
If the issue persists, verify the same IDrive E2 credentials using another S3-compatible client (such as AWS CLI or S3 Browser). If the credentials work successfully, please contact QNAP Support for further assistance with the Signature Version 4 compatibility issue.
Note: Data restoration is handled by your specific backup solution provider and is affected by multiple variables that are unique to your environment. For application-related enquiries/support, it is strongly recommended you seek guidance from the technical team of your backup solution provider.
