5 Dell EMC PowerProtect Data Manager: File System Backup and Recovery | H18659.4 Architecture

2 Architecture

2.1 Block-Based Backup Technology: PowerProtect Data Manager performs file system level full and incremental backup using block-based backup (BBB) technology. During the backup, the application agent scans a volume or a disk in a file system and backs up all the blocks that are in use in the file system. Unlike the traditional file system backup, BBB supports high-performance backups with a predictable backup window.

Block-based backups provide instant access to the backups. The block-based backups enable to the backups by using the same file systems that used to backup the data.

The File System agent's block-based backups support the following capabilities:

- Mounting of a backup as a file system - Mounting of an incremental backup - Sparse backup support - Backups of operating system-deduplicated file systems as source volumes on Windows - Forever virtual full backups to Dell EMC PowerProtect DD series appliances - Data Domain retention lock - Recoveries from DD series

Block-based backups are useful for datasets that are under 10 TB with a single volume under 5 TB, and a daily change rate under 5%.

Figure 1 : Block-Based Backup

6 Dell EMC PowerProtect Data Manager: File System Backup and Recovery | H18659.4 Architecture

2.2 File-Based Backup Technology: File-based backups traverse through the entire of the file system to back up all the files in each directory of the file system. File-based backups provide capabilities such as exclusion, these backups take longer to complete when compared to block-based backups. The file system agent performs file-based backups of the protected assets when an exclusion filter is applied to a protection policy.

Figure 2 : File-Based Backup

2.3 PowerProtect Data Manager enhanced models for file system protection and recovery: Filesystem protection data zone components include PowerProtect Data Manager server, PowerProtect file system agents, host and storage. PowerProtect Data Manager for file system protection has been built with two service model features,

a) Self-service file system protection and recovery b) Centralized file system protection and recovery

7 Dell EMC PowerProtect Data Manager: File System Backup and Recovery | H18659.4 Architecture

Figure 3 : PowerProtect Data Manager enhanced models for file system protection and recovery

a) Self-service file system protection and recovery:

• File system admin or can utilize self-service CLI commands to perform self-service backup or restore

• For a host with file system agent installed, a PowerProtect Data Manager server is required to backup file systems. However, a backup administrator or file who wants to back up file systems manually uses PowerProtect Data Manager only for compliance purposes can register the host to PowerProtect Data Manager and create a self-service protection policy to configure only the retention policy instead of a complete backup schedule

• Once a host is registered with PowerProtect Data Manager and assets are added to a self-service protection policy, self-service or manual backups can be performed on the host's file system assets by using the (ddfssv) command

• Self-service restore can restore from backups that were centralized or self-service and can be done to a local or remote server

Note: To enable self-service protection, self-service protection option is selected when creating the file system protection policy in the PowerProtect Data Manager.

b) Centralized file system protection and recovery:

• Centralized file system model is built for backup administrators to perform policy-based file system backup, recovery, , and long-term retention of copies. With centralized protection feature PowerProtect Data Manager manages the entire file system backup workflow including the schedule

• Centralized protection is supported through protection policy. Once the file system agent is installed on client the client is auto- discovered on PowerProtect Data Manager and enables administrator to approve the client
