This topic describes the causes of overdue payments in Apsara File Storage NAS and the service status changes that are caused by overdue payments.

Causes

An overdue payment occurs due to the following reasons:
  • General-purpose NAS file systems
    • The occupied storage space of a General-purpose NAS file system exceeds the capacity limit of the storage plan that is bound to the file system and your account balance is insufficient.
    • The storage plan that is bound to a General-purpose NAS file system expires and your account balance is insufficient.
    • No storage plan is bound to a General-purpose NAS file system and your account balance is insufficient.
  • Extreme NAS file systems

    The pay-as-you-go billing method is used for an Extreme NAS file system and your account balance is insufficient.

Service status changes

An overdue payment results in the following service status changes:

  • General-purpose NAS file systems
    • To ensure service continuity, you must settle the overdue payment within 15 days.
    • If you do not settle the overdue payment within 15 days, the file systems become unavailable. You are still charged for the storage space. Therefore, the overdue amount continues to increase. If you settle the overdue payment within 22 days, the file systems become available again.
    • If you do not settle the overdue payment within 22 days, Alibaba Cloud assumes that you no longer need NAS. Your data stored in NAS is deleted and you cannot restore the data. Before your data is deleted, you are still charged for the storage space. If you no longer need NAS, we recommend that you delete all data from NAS.
  • Extreme NAS file systems
    • To ensure service continuity, you must settle the overdue payment within 7 days.
    • If you do not settle the overdue payment within 7 days, Alibaba Cloud assumes that you no longer need NAS. Your data stored in NAS is deleted and you cannot restore the data. If you no longer need a file system, we recommend that you delete the file system. Otherwise, you are still charged for the file system.
