1 Step 1: Purchase a Vault

1.1 Purchasing a Server Backup Vault

1.2 Purchasing a Disk Backup Vault

1.3 Purchasing a File System Backup Vault

1.4 Purchasing a Hybrid Backup Vault

1.1 Purchasing a Server Backup VaultThis section describes how to purchase a server backup vault.

Procedure

Step 1 Log in to CBR Console.

1. Log in to the management console.

2. Click in the upper left corner and select the desired region and project.

3. Click and choose Storage > Cloud Backup and Recovery >Cloud Server Backup.

Step 2 In the upper right corner of the page, click Buy Server Backup Vault.

Step 3 Select a billing mode.● Yearly/monthly is a prepaid billing mode. You will be charged based on the

subscription duration you specify. This billing mode is ideal when the resourceuse duration is predictable. This mode provides a more favorable price thanthe pay-per-use mode.

● Pay-per-use is a postpaid billing mode. You will be charged based on actualuse and can purchase or delete resources at any time. Fees are deducted fromthe account balance.

Step 4 Select whether to enable the database backup function.● If the database backup function is enabled, the vault can be used to store

database backups. Backing up memory data through database backupensures application system consistency, which is suitable for ECSs containing

Cloud Backup and RecoveryGetting Started 1 Step 1: Purchase a Vault

MySQL or SAP HANA databases. If a database backup task fails, the systemautomatically performs server backup for the server. The server backups arealso stored in the database backup vault.

● If the database backup function is disabled, only common server backup isperformed on associated servers, which is usually used for ECSs that do notcontain databases.

Step 5 (Optional) In the server list, select the servers or disks you want to back up. Afterthe servers or disks are selected, they are added to the list of selected servers, asshown in Figure 1-1. You can associate selected disks on the server to the vault.

NO TICE

To ensure post-restoration data consistency, you are advised to back up the entireserver.If you want to back up only some disks to reduce costs, ensure that data on thesedisks is independent from the rest. Otherwise, data inconsistency may occur.For example, data of the Oracle application is scattered across different disks. Ifonly some of the disks are backed up, restoration restores only the data of thedisks that have been backed up, with the rest of the data unchanged. As a result,data inconsistency occurs and the application cannot be started.

Figure 1-1 Selecting servers

● Only Running or Stopped servers can be selected.● You can associate desired servers with the vault you created later if you skip this step.

Step 6 Specify the vault capacity. The minimum value of a vault capacity is the totalcapacity of the associated servers and the maximum value is 10,485,760 GB. Youneed to properly plan the vault capacity, which cannot be less than that of theserver to be backed up. Also, note that after automatic association is enabled anda backup policy is bound, the required capacity is larger. You can expand the vaultonce the capacity becomes insufficient.

Step 7 Select whether to configure automatic backup.● If you select Configure, you must then select an existing or create a backup

policy. After the vault is created, the system associates the vault with this



backup policy, and all servers associated with this vault will be automaticallybacked up based on this policy.

● If you select Skip, servers associated with this vault are not automaticallybacked up.

Step 8 If the Enterprise Project Management (EPS) service is subscribed, you can add thevault to an existing enterprise project.

EPS provides a unified method to manage cloud resources by project, allowing youto manage resources, users, and user groups in your projects. The default project isdefault.

Step 9 (Optional) Add tags to the vault.

A tag is represented in the form of a key-value pair. Tags are used to identify,classify, and search for vaults. Tags here are used to filter and manage vaults only.A vault can have a maximum of 10 tags.

Table 1-1 describes parameters of a tag.

If you have associated servers, file systems, or disks when purchasing a vault, skipthis section.

After a server backup vault, a file system backup vault, or a disk backup vault iscreated, you can associate servers or disks with the vault for backup.

After a hybrid cloud backup vault is created, servers and disks cannot beassociated with the vault, but you can synchronize backups for on-premisesservers and storage devices to the cloud. For details, see Hybrid Cloud Backup.

Prerequisites● The servers to be associated must be in the Running or Stopped state.● The disks to be associated must be in the Available or In-use state.● The file systems to be associated must be in the Available or In-use state.● At least one disk is attached to the server.● The total capacity of the resources to be associated cannot be greater than

the capacity of the vault.

Procedure




3. Click and choose Storage > Cloud Backup and Recovery.

Step 2 On the backup page, locate the target vault and click Associate Server, AssociateFile System, or Associate Disk in the Operation column. See Figure 2-1.

Figure 2-1 Associating a server

Step 3 Click OK. Then in the Associated Servers column in the vault list, you can viewthe number of resources that have been successfully associated.

----End

Automatic Association

Backup vaults support automatic association with resources that are not backedup. After successful association, resources will be backed up according to thebackup policy bound to the vault.

● If multiple vaults are enabled with automatic association, the system scansthe backup policies and associates resources with the vault whose nextscheduled backup time is the earliest.

● When the association capacity of the vault selected by the system is full,resources will be associated with the vault whose next scheduled backup timeis the second earliest.

● If there is more than one vault whose next scheduled backup time is theearliest, the system randomly associates the resources with one of thesevaults.

● If a vault is enabled with automatic association but not bound to any backuppolicy, no resource will be automatically associated with it. You can manuallyassociate resources that have not been backed up with the vault.

● After the automatic association function is disabled for a vault, the vault stopsautomatically scanning for resources that have not been backed up. Theassociated resources are not affected.




3. Click and choose Storage > Cloud Backup and Recovery.

Step 2 Select Cloud Server Backup or Cloud Disk Backup from the navigation tree onthe left and find the target vault.



Step 3 Choose More > Enable Automatic Association in the Operation column of thevault. See Figure 2-2.
