firewall
Glossary-6
firewall
A system designed to prevent unauthorized access to or from a private network.
full backup
An operation that backs up all of the files selected on a client. Unlike in an
incremental backup, files are backed up whether they have changed since the last
backup or not.
heterogeneous network
A network made up of a multitude of computers, operating systems, and applications
of different types from different vendors.
host authentication
The initialization phase of a connection between two hosts in the administrative
domain. After the hosts authenticate themselves to each other with identity
certificates, communications between the hosts are encrypted by Secure Sockets
Layer (SSL). Almost all connections are two-way authenticated; exceptions include
initial host invitation to join a domain and interaction with hosts that use NDMP
access mode.
identity certificate
An X.509 certificate signed by the Certification Authority (CA) that uniquely
identifies a host in an Oracle Secure Backup administrative domain.
incremental backup
An operation that backs up only the files on a client that changed after a previous
backup. Oracle Secure Backup supports 9 different incremental backup levels for
file-system backups. A cumulative incremental backup copies only data that changed
since the most recent backup at a lower level. A differential incremental backup,
which is equivalent to a level 10 backup, copies data that changed since an incremental
backup at the same or lower level.
An incremental backup contrasts with a full backup, which always backs up all files
regardless of when they last changed. A full backup is equivalent to an incremental
backup at level 0.
job list
A catalog created and maintained by Oracle Secure Backup that describes past,
current, and pending backup jobs.
job summary
A text file report produced by Oracle Secure Backup that describes the status of
selected backup and restore jobs. Oracle Secure Backup generates the report according
to a user-specified job summary schedule.
job summary schedule
A user-defined schedule for generating job summaries. You create job summary
schedules with the mksum command in obtool.
location
A location is a place where a volume physically resides; it might be the name of a tape
library, a data center, or an off-site storage facility.
