NSR_LAYOUT(5) Legato NetWorker 4.1.1 NSR_LAYOUT(5)
NAME
NSR Layout - NetWorker file layout
DESCRIPTION
The NetWorker server filesystem has a directory called /nsr that
contains log files, on-line indexes, and configuration information.
This directory can be created in any filesystem with /nsr set up as a
symbolic link to the actual directory (this is determined at
installation time). The format of this directory is as follows:
/nsr/logs
Contains server logging messages. The files in this directory
are in ASCII format.
/nsr/res
Contains the configuration files for various components of the
NetWorker server. For example, the server stores configuration
files in /nsr/res/nsr.res and /nsr/res/nsrjb.res.
/nsr/mm
Contains the media index. Information about the contents of
this index file can be printed with the nsrls(8) command. See
the nsrmm(8) and mminfo(8) manual pages on how to view and
manipulate the media index information.
/nsr/index
This directory contains subdirectories with names that
correspond to the NetWorker clients that have saved files.
Each index directory contains files that allow the NetWorker
server to provide an on-line database of the client's saved
files. The most important file is the db file which contains
the NetWorker save records and access indexes to those
records. This index file grows with the number of files saved
by the NetWorker service. Administrators should plan to use
about 200 bytes per saved file instance placed in this index.
An index may grow to a maximum of 1GB in size, with the first
40KB allocated for internal use.
The format of the db file is subject to change, and is
accessible only through an RPC interface to nsrindexd(8).
However, the command nsrls(8) can be used to obtain some
useful statistics from this file.
The existence of the db.SCAVENGE file indicates that the
associated db file may need to be checked. The nsrck(8)
command is used for checking and rebuilding index files.
While checking is taking place, the db.SCAVENGE file may
contain the save records that will be used to rebuild db. If
the filesystem does not have enough free space to contain
db.SCAVENGE, then the file will be a symbolic link to a
temporary file in some other local filesystem.
The file db.RECOVER is where nsrck ``rebuilds'' a fresh index.

Upon completion this file is renamed to db.
/nsr/cores
Contains directories that correspond to the NetWorker server
daemons and certain executables. Each directory may contain
core files from NetWorker server daemons or executables that
have abnormally terminated.
/nsr/drivers
This directory may contains any device drivers for use with
NetWorker.
/nsr/tmp
This directory contains temporary files used by the Networker
system.
The executables for the NetWorker system are usually installed in the
directories /usr/etc or /usr/bin, though alternate locations may be
chosen when the nsrize(8) installation script is run. Alternate
locations are not available on SCO systems that install with
custom(ADM). See pkgadd(1M) for details on alternate executable
locations for Solaris 2.x.
When executables for more than one architecture are installed, the
non-native architectures are by default put in the directory
/export/exec/arch/etc, where arch refers to a given architecture
name. A different location to install non-native executables can be
chosen at installation time.
FILES
/nsr NetWorker indexes, log files, and configuration
information.
/usr/etc, /usr/bin Where NetWorker executables for the native
architectures are normally installed.
/export/exec/arch/etc
Where NetWorker executables for non-native
architectures are normally installed.
/usr/bin, /usr/sbin, /usr/lib/nsr
Where NetWorker executables for Solaris 2.x are
normally installed.
