Overview
Archive Configuration
Archiving is managed by one or more archive device objects which are configured
in the Node Administration structure. An archive device is a logical entity that
defines where and how archive data is written. Every MO or disk drive used for
archiving must have at least one archive device aspect configured for it. A single
drive may have several archive devices configured for it to satisfy different archive
requirements. For example, more sensitive data may be archived through a separate
device which is configured to prevent automatic overwriting of stored data.
Archiving may be scheduled to occur on a periodic or event-driven basis through the
Application Scheduler, or execute manual archive operations on demand. For
manual archives, if the specified time range has no samples, no data will be
archived. For scheduled archives, even if no new samples were collected, at least
one sample (the last valid point) will be archived. Each archive operation is referred
to as an archive entry.
Scheduled archiving is implemented through archive groups. These are user-defined
groups of logs which are archived together as a single unit. Scheduling instructions
for archive groups are specified in job description objects created in the Scheduling
structure. The schedules are associated with their respective archive groups through
an Archive Action aspect attached to the job description object. Manual archiving
may be done on an archive group basis, or by selecting individual logs.
Accessing Archived Data
Archive volumes support viewing of archive data (through the corresponding
archive volume aspect). The MO media has one archive volume. Partition the hard
disk media into any number of archive volumes. Archive volumes are automatically
created for all removable disk drives (DVD and CD drives) to support viewing of
archive data on DVDs and CDs which contain archive files. Further, additional read-
only volumes can be created for reading archive volumes that have been copied to a
mapped network drive, or for viewing archive files that have been copied to the local
drive.

shadow copies as needed.
