EVS recycle bin is disabled by default. You need to manually enable it before you can use it.

If the recycle bin is enabled, EVS disks will be moved to the recycle bin upon deletion. This can help protect your disk data from accidental deletions.

To learn when deleted disks will be moved to the recycle bin, see Recycle Bin Rules for Deleted EVS Disks.

You can configure a recycle bin policy to define when to move deleted disks to the recycle bin.

NOTE:

See the EVS recycle bin region availability in Function Overview.

Notes and Constraints

When you delete a disk, regardless of whether the disk will be moved to the recycle bin or not, legacy snapshots of the disk will always be deleted permanently.
There are no limits on the capacity and quantity of disks in the recycle bin.
Separately deleted disks are stored in the recycle bin for a maximum of seven days. During this period, you can recover or permanently delete the disks. After the disks expire, they are permanently deleted and cannot be recovered.
If you have disks already in the recycle bin and then your account goes in arrears, the disks will enter a grace period and then a retention period, and may be kept for less than 7 days before they are deleted permanently by the system.

Billing Description

EVS disks in the recycle bin are billed on a pay-per-use basis. For details, see Billing for EVS Recycle Bin.

Recycle Bin Rules for Deleted EVS Disks

When will EVS disks be moved to the recycle bin?

You first have to configure a recycle bin policy to define when to move deleted disks to the recycle bin. Then, disks will be moved there if:

You delete pay-per-use disks or unsubscribe from yearly/monthly disks before they expires.
You delete the cloud service resources that use the disks. The cloud services include ECS, BMS, CCE, and MRS.
You reinstall the ECS OS, and the system automatically creates a new system disk and deletes the old system disk.

EVS disks will not be moved to the recycle bin if:

Your account is restricted or frozen.
The number of days elapses since the disk creation is less than what you specified in the recycle bin policy.
The pay-per-use disks you deleted or yearly/monthly disks unsubscribed from are already in a grace or retention period.
The system permanently deletes the pay-per-use disks or yearly/monthly disks whose retention period has expired.

Recycle Bin Policy Configuration Suggestions

When using the recycle bin, you need to configure a recycle bin policy. For details, see Configuring a Recycle Bin Policy.

Both ECS and EVS support the recycle bin function, and their recycle bin policies can be configured separately. If you use both recycle bins, you are advised to configure the same minimum number of days for moving ECSs and EVS disks to the recycle bins to avoid issues brought by different lifecycles.

In special cases, you may need to configure different recycle bin policies for ECS and EVS. For details, see Table 1.

Assume that an ECS (including a system disk and a data disk) was created 8 days ago. If you delete or subscribe from the ECS, the results would be as follows.
