OSB Terminology (**):
Admin domain:A group of computers on your network that you manage as a common unit to perform backup and restore operations. An administrative domain must include one and only one administrative server. It can include the following:• One or more clients• One or more media serversAn administrative domain can consist of a single host that assumes the roles of administrative server, media server, and client.
Client:Any computer or server whose files Oracle Secure Backup backs up or restores.
Media Server:A computer or server that has at least one tape device or disk pool connected to it. A media server is responsible for transferring data to or from the devices that are attached to it.
OSB Terminology, cont..:
Disk Pool: A file-system directory that stores backups. Disk pools can be accessed concurrently by multiple backup or restore jobs.
Dataset:The contents of a file-system backup. A dataset file describes a dataset. For example, you could create the dataset file my_data.ds to describe a dataset that includes the /home directory on host myhost2.
Media Family:A named classification of backup volumes that share the same volume sequence file, expiration policy, and write window.

OSB Integration with OEM:
After installing admin domain, add OSB as a target to OEM

Oracle Cloud Infrastructure Storage Software Appliance – Cloud Distribution+ Oracle Secure Backup+ OEM
High Level Steps:
1. Download Appliance Image from http://www.oracle.com/technetwork/topics/cloud/downloads/index.html2. Upload image to Compute -> Images and associate Image3. Complete all networking setup 4. Provision VM using the private image (either using the provisioning tool or through the web service console)5. Login to Appliance Console through browser6. Create filesystem7. Mount NFS on VM you want to backup8. Use OEM/RMAN to backup the database to NFS9. Use OEM/OSB to backup filesystems
IaaS: Backups
After provisioning the appliance, create a filesystem using the console:

Oracle Public Cloud Backups
• IaaS
• DBCS
IaaS: Backups
There are multiple options – all managed through OEM:
Database backups:1. Backup to local storage on the IaaS host2. Use the Oracle Cloud Infrastructure Storage Software Appliance (Cloud) to mount an NFS and backup the
database to the NFS3. Use Oracle Database Backup Service
OS backups:1. Snapshots (point in time)2. OSB combined with OEM and Oracle Cloud Infrastructure Storage Software Appliance (Cloud)

Integrating OEM with Cloud hosts:
Steps:
1. Configure an on-premise management agent as a Gateway agent2. Validate connectivity and ssh key setup between the gateway agent host and the cloud host(s)3. Define credentials in OEM4. Deploy agent to cloud host(s)
