Description

The HCI residual information protection function allows users to completely erase existing data during resource recycling. Equal protection or secret-related scenarios require that the storage space supports data erasure during recycling to ensure important data security. Users can customize the number of overwrites according to regulatory requirements or business needs and choose to completely erase existing data during resource recycling.

Precautions

1. CPU and IO resources will be occupied when using the data erasure function. Therefore, the erasing process will take a certain amount of time, so performing it when the business is idle is recommended.
2. After erasing, the data cannot be recovered.
3. After the erasure rate is modified, it will take effect for all data erasure tasks. The actual rate will be dynamically adjusted according to the storage IO performance and busyness.

Steps

1. Enter the System > Recycle Bin interface, and click Settings to configure the data erasing rate and erasing speed.
2. If Data Erasure is enabled, when deleting virtual network devices, virtual machines, shared disks, residual directories in the recycle bin, and deleting virtual disks of virtual machines, the data will be erased at the same time. Keep data safe.

3. Click the Virtual Machines tab. Select the virtual machine and click Delete or click Empty. The operation will prompt the option: Delete the backups of the virtual machine. Backups will be stored in Recycle Bin for 30 days before being permanently deleted.  Check this checkbox and enter the HCI administrator password to completely erase the virtual machine's data.
