Recommended scenarios
Sharing and storage of a small volume of logs and data. Small websites and user-created FTP sites.
Sharing and storage of logs and data. Sharing data across multiple regions. Share directories, user-created FTP sites, small-sized websites, data archives, and data warehouses.
Unified storage of data and logs. Archiving of large amounts of data. Data sharing among multiple regions. Medium-sized websites, virtual desktop infrastructure (VDI)-based share directories, code libraries, and data warehouses.

Features
The following table lists the specifications of the express synchronization and reverse synchronization 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.
Reverse synchronization
< 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 reverse synchronization interval.
Costs are based on the scanning interval and total number of files.
