Billing

Billing Items

Pay-per-use billing is preset by default. You can create a general-purpose file system for free and pay only for the used storage space based on for how long you use the file system. You will be billed for the file system by the hour, and there is no minimum cost. Any usage period of less than an hour is rounded up to an hour.

Overdue Payment

Possible causes of overdue payment:

If the usage of your expenditure quota reaches or exceeds 100% and you do not make payments in a timely manner, a grace period starts.

Service status and operation restrictions when an account is in arrears:

Your general-purpose file systems are retained after your account is in arrears and file systems enter a retention period, but you cannot use the file systems. If the outstanding payment is not cleared before the retention period ends, data stored in the file systems will be deleted and cannot be recovered.

For details about the retention period, see Resource Suspension and Release.
