Term 
+++ Description
Backup Server 
+++ The backup server is a computer that receives backup data
from client computers on the network. The data is indexed and stored in a
media database and then sent to a backup storage device (usually a tape).
The backup server also facilitates future data recovery.
Backup Client 
+++ The backup client is any computer on which backup software
installed that allows the backup server to back up its data. A backup
client does not have to be the same platform or operating system as the
backup server.
Storage Node 
+++ A storage node is a computer connected to one or more
storage devices, such as tape libraries and tape drives, that are used in
backup and recovery operations. The backup server  (or multiple backup
servers) controls the storage node.
Catalog 
+++ Backup catalogs are databases that reside on the backup server that
track the files that backed up from the backup clients. In addition,
catalogs track the volume on which the data resides as well as the date and
time the files were backed up.
Data Set 
+++ The data set is typically the set of files or file systems that
are backed up from a backup client to a backup server (or backup storage
node).
Media Duplication 
+++ Backup servers can make duplicates, or clones, of
complete volumes of stored data as well as individual data sets. This
allows for secure offsite storage, easy transfer of data from one location
to another and verification of backups.
Staging 
+++ The staging process captures files or directories, as they exist at
a specific time, and writes the data to special staging storage volumes.
After the staging process completes, you can delete (groom) the original
files from the disk to conserve space.
Database Agent 
+++ Database agents are software installed on backup clients
that contain databases to be backed up such as Oracle, Sybase, MS-Exchange,
MS-SQL, Informix, etc. The database agents allow hot backups of the various
databases previously mentioned thus preventing the databases to be shutdown
prior to the backups of the databases occurring.
