How Harbor Enterprise NSM works

Harbor Enterprise NSM Architecture
Harbor Enterprise NSM on z/OS consists of a highly scalable backup server and a policy server hosted on the z/OS platform. Harbor Enterprise NSM Backup Clients are installed on each open-systems platform, and Harbor Enterprise NSM Backup Agents are installed on each database and email server.

Each backup server supports multiple clients and agents, which work with the backup server to provide backup/restore and archive/retrieve functions. Backup servers as well as backup jobs are governed by enterprise-wide policies stored on the policy server and managed via the administration console. The Harbor Enterprise NSM administrator defines the backup and storage policies that will be applied to every backup job, such as whether to do full or incremental backups, how many versions to retain, or what storage class to use.

How Backups Work
Backup jobs are automatically initiated to an established schedule. Each client forwards a list of candidate backup files, which the backup server trims according to the appropriate retention and exclusion policies. The reduced file list is returned to the client. The client first compresses, if configured to utilize compression, and then transmits only the files left on the list. LAN-less backups utilize ESCON/FICON channels for ultra-fast data transmission.

Harbor Enterprise NSM manages a multitude of backup jobs simultaneously, forwarding the data from each job to storage according to the appropriate storage policy. As jobs complete, queued up backup jobs are released for data transmission. During non-backup times, Harbor Enterprise NSM consolidates backup data into condensed packages, enabling best possible restore times. Duplicate backup data tapes are sent, electronically or physically, to the corporate disaster recovery site.

Harbor NSM Solution Implementation
Harbor Enterprise NSM integrates a mainframe-hosted backup server to provide a seamless backup and recovery solution throughout the enterprise. With its central policy server and single point of administration, Harbor Enterprise NSM manages the entire enterprise regardless of whether data is backed up. Harbor Enterprise NSM provides the ability to manage data remotely and the flexibility to set policy globally across the organization or according to the needs of the regional office.
