Application Scenarios
After a file system is unsubscribed, the data stored in the file system cannot be recovered. To avoid data loss, make sure that all files stored on the file system are backed up before unsubscribing.
Precautions
When unsubscribing a file system, all the file system data is deleted. Please operate with caution.
Unsubscribed file systems are not recoverable. Please operate with caution.
The Annual/Monthly Package file system supports unsubscribing.
To unsubscribe from a file system, you must unbind all VPCs.
Procedure
You can unsubscribe resources that have been newly purchased with an Annual/Monthly package in full amount within seven days after subscription without specific reason (Please note that this does not apply to the instances that have undergone capacity expansion and renewal operations). To unsubscribe non-newly purchased resources with an annual/monthly subscription, certain conditions must be met. For details, see Unsubscribing Rules.
1. Log in to the eSurfing Cloud Console, click 
in the upper left corner of the console, and select a region.
2. Select Storage Console > Scalable File Service. Go to the Scalable File Service page and find the destination file system that you want to delete in the file system list.
