For WHMCS installations with a high volume of attachments, managing these files directly on the server can lead to performance issues and inode overuse. To address this, we recommend integrating an S3-type storage solution, such as Amazon S3, Wasabi, or iDrive E2. This approach not only streamlines file management but also offers cost-effective storage options.

Step 1: Choose Your S3-Type Storage Provider

Select a storage provider that meets your needs in terms of pricing, features, and reliability. Providers like Amazon S3, Wasabi, and iDrive E2 offer scalable solutions suitable for WHMCS attachments. 

Step 2: Configure Your Storage Provider in WHMCS

Follow the guide provided by WHMCS to configure your chosen S3 storage provider: Configuring an Amazon S3 Storage Provider in WHMCS

Step 3: Migrate Existing Attachments to S3 Storage

Once your S3 storage is configured, migrate your local files using the steps outlined by WHMCS: Migrating from Local File Storage to Amazon S3

Step 4: Consider File Retention and Costs

By moving to S3 storage, you can benefit from cost-effective pricing models, such as those offered by iDrive E2, which can be as low as $15 per year, depending on storage requirements. Review the pricing details for iDrive E2 here: iDrive E2 Pricing

By following these steps, you can efficiently manage your WHMCS attachments, ensuring better performance and scalability for your hosting environment.
