Features
The following table describes the express synchronization and reverse synchronization features.
Feature
Number of files
Metadata synchronization rate
File synchronization interval
Monthly cost
Express synchronization
> 5,000,000
Maximum synchronization rate: 1,000 incremental files per second.
Subseconds. The maximum update interval equals the interval at which the cache of the NFS or SMB client is refreshed.
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 comparison.
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.
