Avamar system overview
An Avamar system is a client/server network backup and restore solution.
An Avamar system consists of one or more Avamar servers and the network servers or desktop clients that back up data to those servers. The Avamar system provides centralized management through the Avamar Administrator graphical management console software application.
Avamar server
Avamar is a hard disk based IP network backup and restore solution. Avamar servers use internal hard disk storage. An Avamar server is a logical grouping of one or more nodes that is used to store and manage client backups.
Hardware manufacturers typically call their equipment servers (for instance, the Dell PowerEdge 2950 server). In the context of an Avamar system, this equipment is called a node. An Avamar node is a self-contained, rack-mountable, network-addressable computer that runs Avamar server software on the Linux operating system.
Avamar ensures fault tolerance by managing disk drive space in units of space called stripes.
In the Avamar system, an object is a single instance of deduplicated data. Each Avamar object inherently has a unique ID. Objects are stored and managed within stripes on the Avamar server.
