During a backup process, the data in the memory will not be automatically written onto EVS disks, resulting in data inconsistency between EVS disks and their backups.
You can create snapshots of the BMS system disk on the EVS console periodically. To restore the system disk data, mount the target system disk to the sda mount point. Power off the BMS. Log in to the management console. Under Computing, click Bare Metal Server.

A FlexusL instance is a package of resources that include cloud servers, EVS disks, EIPs, CBR vaults, and HSS. Resources in the package are created and managed as a whole. FlexusL instances provide various images to help you quickly set up service environments.

Specifically, use ECS or BMS for server computing resources, and EVS and SFS for storage. For the deployment solution design, refer to section Deployment Plan.
A FlexusL instance is a package of resources that include cloud servers, EVS disks, EIPs, CBR vaults, and HSS. Resources in the package are created and managed together.
Cloud Eye collects ECS and EVS disk data every 4 minutes (5 minutes for KVM ECSs). In contrast, the data is collected in ECS every second. The larger the sampling period, the greater the data distortion in the short term.
If you have added an EVS disk after backup, using the backup to restore data will not change the data on the EVS disk. If you have deleted an EVS disk after backup, using the backup to restore data will not include the data on the EVS disk. Parent topic: About Restoration

Use the API described in Querying Details About an EVS Snapshot (OpenStack Cinder API v2). URI GET /v2.1/{project_id}/os-snapshots/{snapshot_id} Table 1 describes the parameters in the URI.
You can also choose to delete the EVS disks and EIPs together with the selected ECSs. If you do not delete them, they will be retained. If necessary, you can manually delete them later. To delete selected ECSs, perform the following operations: Log in to the management console.
NOTE: When creating a backup for an EVS disk through VBS, a snapshot will be created and named with prefix autobk_snapshot_. The EVS console has imposed operation restrictions on snapshots with prefix autobk_snapshot_.

ECS Overview An ECS is a basic computing unit that consists of vCPUs, memory, OS, and EVS disks. After creating an ECS, you can use it like using your local computer or physical server, ensuring secure, reliable, and efficient computing.
