CBR Concepts

CBR stores backups of a variety of resources in vaults, which are classified into the following types:

• Server backup vaults: store backups of non-database servers or database servers. You can associate servers with a vault and apply a backup policy. You can then use the backups for restoration.
• Disk backup vaults: store only disk backups. You can associate disks with a disk backup vault and apply a backup policy to schedule automatic backups.
• SFS Turbo backup vaults: store only backups of SFS Turbo file systems. You can associate file systems with an SFS Turbo backup vault and apply a backup policy to schedule automatic backups.

A backup is a copy of a particular chunk of data and is usually stored elsewhere so that it can be used to restore the original data in the event of data loss. It can be generated either manually by a one-off backup task or automatically by a periodic backup task.

A one-off backup task is manually created and is executed only once. Periodic backup tasks are automatically executed based on a user-defined backup policy.

• One-time backup names can be user-defined or assigned automatically by the system. System-generated names follow the manualbk_xxxx format.
• A periodic backup is automatically named autobk_xxxx by CBR.

A backup policy is a set of rules that define the schedule and retention of backups. After you apply a backup policy to a vault, CBR automatically backs up data and retains backups based on that backup policy.

Instant Restore restores data and creates images from backups, much faster than a normal restore.

Instant Restore is an enhanced function of CBR and requires no additional configuration. After Instant Restore is provided, you take less time to restore server data or create images.

Enhanced backups are backups generated after Instant Restore is provided. Enhanced backups make it faster to restore server data or create images. If Instant Restore Support is Yes in the backup details, the backup is an enhanced backup. Otherwise, the backup is a common backup.

Before providing Instant Restore, CBR generates common backups. After providing Instant Restore, CBR first performs a full backup for each associated resource and then generates enhanced backups. CBR only generates enhanced backups for new resources currently.

For the same resource, an enhanced backup and a common backup have the same backup content and size. They only differ in the restoration speed.
