NSR_LAYOUT(5) Legato NetWorker 4.0 NSR_LAYOUT(5)
NAME
NSR Layout - NetWorker file layout
DESCRIPTION
The NetWorker server filesystem has a directory called /nsr that con
tains 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 instal
lation 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 corre
spond 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 Net
Worker save records and access indexes to those records. This
index file grows with the number of files saved by the Net
Worker 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 acces
sible only through an RPC interface to nsrindexd(8). However,
the command nsrls(8) can be used to obtain some useful statis
tics from this file.
The existence of the db.SCAVENGE file indicates that the asso
ciated db file may need to be checked. The nsrck(8) command
is used for checking and rebuilding index files. While check
ing 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. Each directory may contain core files from NetWorker
server daemons that have abnormally terminated.
/nsr/sjidriver
This directory contains the jukebox device driver installation
directory.
/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 another location may be cho
sen when the nsrize(8) installation script is run.
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
infromation.
/usr/etc, /usr/bin Where NetWorker executables for the native archi
tectures are normally installed.
/export/exec/arch/etc
Where NetWorker executables for non-native archi
tectures are normally installed.
