public key
Glossary-10
root
user identity. On Windows systems, the backup runs under the same account
(usually
Local System
) as the Oracle Secure Backup service on the Windows client.
public key
A number associated with a particular entity intended to be known by everyone who
must have trusted interactions with this entity. A public key, which is used with a
corresponding
private key , can encrypt communication and verify signatures.
Recovery Manager (RMAN)
A utility supplied with Oracle Database used for database backup, restore, and
recovery. RMAN is a separate application from Oracle Secure Backup. Unlike RMAN,
you can use Oracle Secure Backup to back up any file on the file system—not just
database files. Oracle Secure Backup includes an
SBT interface that RMAN can use to
back up database files directly to tape.
retention period
The length of time that data in a volume set is not eligible to be overwritten. The
retention period is an attribute of a time-managed media family . The retention period
begins at the write window close time . For example, if the write window for a media
family is 7 days, then a retention period of 14 days indicates that the data is eligible to
be overwritten 21 days from the first write to the first volume in the volume set .
rights
Privileges within the administrative domain that are assigned to a class . For example,
the
perform backup as self
right is assigned to the
operator
class by default.
Every Oracle Secure Backup user that belongs to a class is granted the rights
associated with this class.
roles
The functions that hosts in your network can have during backup and restore
operations. There are three roles in Oracle Secure Backup:
administrative server ,
media server , and client . A host in your network can serve in any of these roles or any
combination of them. For example, the administrative server can also be a client and
media server.
SAN
See Storage Area Network (SAN)
SBT interface
A media management software library that Recovery Manager (RMAN) can use to
back up to tertiary storage. An SBT interface conforms to a published API and is
supplied by a media management vendor. Oracle Secure Backup includes an SBT
interface for use with RMAN.
scheduled backup
A file-system backup that is scheduled through the
mksched
command in obtool or
the Oracle Secure Backup Web tool (or is modified by the
runjob
command). A
backup schedule describes which files should be backed up. A trigger defined in the
schedule specifies when the backup job should run.
scheduler
A daemon (obscheduled) that runs on an administrative server and is responsible for
managing all backup scheduling activities. The scheduler maintains a job list of
backup job operations scheduled for execution.
