This topic describes overdue payments for Apsara File Storage NAS and how the status of NAS changes when overdue payments occur.

Causes

An overdue payment occurs due to one of 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 system
    • To ensure service continuity, you must settle overdue payments in 15 days.
    • If you do not settle overdue payments in 15 days, NAS becomes unavailable. You are still charged for the storage space. Therefore, the overdue amount continues to increase. If you settle overdue payments in 22 days, NAS becomes available again.
    • If you do not settle overdue payments in 22 days, Alibaba Cloud assumes that you no longer require NAS. Your data stored in NAS is deleted. You cannot restore your data. Before your data is deleted, you are still charged for the storage space. If you no longer require NAS, we recommend that you delete all data from NAS.
  • Extreme NAS file system
    • To ensure service continuity, you must settle overdue payments in 15 days.
    • If you do not settle overdue payments in 7 days, Alibaba Cloud assumes that you no longer require NAS. Your data stored in NAS is deleted. You cannot restore your data. If you no longer require NAS, we recommend that you delete all NAS file systems. Otherwise, you are still charged for the storage space of your file systems.
