Copia de respaldo de EVS

¿Qué es copia de respaldo de EVS?

Cloud Disk Backup proporcionado por Cloud Backup and Recovery (CBR) le permite crear copias de seguridad para sus discos EVS mientras servidors se están ejecutando. Si se producen pérdidas o daños de datos debido a invasiones de virus, eliminaciones accidentales o fallos de software/hardware, puede utilizar copias de seguridad para restaurar los datos, garantizando la integridad y seguridad de sus datos.

Cloud Disk Backup es una función ofrecida por CBR. Para obtener más información sobre CBR, consulte Arquitectura de productos CBR.

CBR Architecture

CBR involves backups, vaults, and policies.

Backup

A backup is a copy of a particular chunk of data and is usually stored elsewhere so that it may be used to restore the original data in the event of data loss. There are the following types of backups:

• Cloud disk backup: provides snapshot-based backups for EVS disks.
• Cloud server backup: uses the consistency snapshot technology to protect data for ECSs and BMSs. Backups of non-database servers are non-database server backups, and those of database servers are application-consistent backups.
• SFS Turbo backup: backs up data of SFS Turbo file systems.
• Hybrid cloud backup: protects data of on-premises OceanStor Dorado storage systems and VMware VMs by storing their backups to the cloud. You can manage the backups on CBR Console.
• File backup: backs up data of a single or multiple files, instead of the entire cloud servers or on-premises hosts.

Vault

CBR stores backups in vaults. Before creating a backup, you need to create at least one vault and associate the resources you want to back up with the vaults. Then the resources can be backed up to the associated vaults.

Vaults can be either backup vaults or replication vaults. Backup vaults store resource backups, and replication vaults store backup replicas.

Different types of resources must be backed up to different types of vaults. For example, cloud servers must be backed up to server backup vaults, not disk backup vaults or any other types of vaults.

Policy

There are backup policies and replication policies.

• A backup policy defines when you want to take a backup and for how long you would retain each backup.
• A replication policy defines when you want to replicate from backup vaults and for how long you would retain each replica. Backup replicas are stored in replication vaults.
