As a global concept, backup storage refers to the back-end storage space for use by the eBackup backup management system, which consists of storage units, storage pools, and repositories.

Failure to access the eBackup storage plane
Security of the eBackup has been hardened. By default, only those external systems which are in the same network segments as the eBackup network planes can access eBackup servers. Therefore, you need to configure other network segments or IP addresses that need to be connected to the storage plane (including the production storage plane and the backup storage plane). Configure routes and firewalls in sequence.

Capacity of shared storage when the backup policy of the eBackup management data is daily backup
If the backup policy of the eBackup management data backup is set to Daily Backup, capacity of shared storage for storing backup management data = [(Number of yearly backup copies + Number of monthly backup copies + Number of weekly backup copies + Number of daily backup copies + 1) x 10 + 15] GB. For example, when the default retention policy is used, the capacity of shared storage for storing backup management data = [(0 + 1 + 1 + 1 + 1) x 10 + 15] GB = 55 GB. When Yearly Backup is set to Permanent, planned capacities depend on the number of years for saving backup copies. The capacity of shared storage for storing backup management data = [(Number of planned yearly backup copies + Number of monthly backup copies + Number of weekly backup copies + Number of daily backup copies+ 1) x 10 + 15] GB.

Capacity of shared storage when the backup policy of the eBackup management data is hourly backup
If the backup policy of the eBackup management data is set to Hourly Backup, capacity of shared storage for storing backup management data = [(Number of yearly backup copies + Number of monthly backup copies + Number of weekly backup copies + Number of daily backup copies + Number of hourly backup copies + 1) x 10 + 15] GB. For example, when the default retention policy is used, the capacity of shared storage for storing backup management data = [(0 + 1 + 1 + 1 + 1 + 1) x 10 + 15] GB = 65 GB. When Yearly Backup is set to Permanent, planned capacities depend on the number of years for saving backup copies. The capacity of shared storage for storing backup management data = [(Number of planned yearly backup copies + Number of monthly backup copies + Number of weekly backup copies + Number of daily backup copies + Number of hourly backup copies + 1) x 10 + 15] GB.

Storage locations of backup files in a FusionInsight HD environment
Databases and configuration files for the Manager component, user information, DBService metadata, and HDFS metadata files can be downloaded through the backup management page of FusionInsight Manager. The storage locations of HBase user service data and HDFS user service data are user-defined.
