nsrmmdbasm - NetWorker module for saving and recovering media databasesSYNOPSIS
nsrmmdbasm [ standard-asm-arguments ]
DESCRIPTION
The nsrmmdbasm is a standard, external ASM (Application Specific Mod-
ule) that assists in the saving and recovering of the NetWorker media
multiplexor's database files.
See uasm(1) for a general description of ASMs and the [standard-asm-ar-
guments]. It is intended that nsrmmdbasm only be invoked by
nsrmmdbd(1) or mmrecov(1) operations.
Features of nsrmmdbasm performance specific to the NetWorker applica-
tion during a save are:
Architecture independence:
The high speed access methods and data structures implemented by
the database code are machine-dependent. This ASM saves only
the records (and not access indexes) in an architecture-indepen-
dent manner. Therefore, NetWorker media databases may be saved
from one machine architecture and recovered to another.
Conservation:
Since only changed records are saved, and not internal indexes,
considerable network bandwidth and tape space are conserved.
The recover operation of this ASM is the inverse of the save operation.
FILES
/nsr/mm/.nsr This directive file causes most files in the direc-
tory to be skipped during normal save operations.
nsrmmdbasm ignores this directive.
/nsr/mm/mmvolume6 The directory which is saved and recovered by this
ASM.
/nsr/mm/mmvolume.r A temporary file that stores the contents of a re-
covered media database until nsrmmdbd(1) has com-
pleted building a new media database.
/nsr/mm/mmvolume.s A temporary file that this ASM reads when backing
up data.
/nsr/mm/volume.tmp A temporary file created when converting an older
media database schema to the present schema during
recovery.
