  • Features

    The following table lists the specifications of the express synchronization and remote sync features. You can select the features based on your business requirements.

    Features Number of files Metadata synchronization rate File synchronization frequency Monthly cost
    Express synchronization > 5,000,000 Maximum synchronization rate: 1,000 incremental files per second. Less than one second. The maximum update interval is the refresh interval of the NFS/SMB client cache. Fixed. If the number of API calls is less than 20,000,000 per month (30 days), the cost is calculated by using the following formula: (2+0.5 × number of shares) × 30.
    Remote sync < 5,000,000 The synchronization rate depends on the time consumed for data scanning and matching. More than 15 seconds. The maximum update interval is two times the remote sync interval. Costs are based on the scanning interval and total number of files.
