nisbackup(1M)
NAME
nisbackup - backup NIS+ directories
SYNOPSIS
nisbackup [-v] backup-dir directory...
nisbackup [-v] -a backup-dir
DESCRIPTION
nisbackup backs up a NIS+ directory object on a NIS+ master
server. Updates to the NIS+ database will be temporarily
disabled while nisbackup is running. The backup-dir is a
UNIX directory that must exist prior to running nisbackup.
The nisbackup command can be used to backup an individual
NIS+ directory object or all ( -a) of the NIS+ directory
objects served by a master server. The NIS+ directory
objects being backed up will be placed into subdirectories
under the backup-dir directory. These subdirectories are
named according to the NIS+ directory object they contain.
nisbackup operates on individual NIS+ directory objects
(for example, org_dir.wiz.com). This allows an administra-
tor to selectively backup specific directories.
The rpc.nisd(1M) process must be running on the master
server with a stable NIS+ database for nisbackup to com-
plete. nisbackup will not attempt to correct any corruption
in the NIS+ database, so it is important that backups be
done regularly as part of the NIS+ administration.
The first synopsis is used to backup a single NIS+ directory
object or a list of NIS+ directory objects. The objects can
be partially qualified or fully qualified. The machine on
which the command is executing must be the master for the
NIS+ directory objects specified.
The second synopsis will backup all of the NIS+ directory
objects that are served by this master. The -a option is
the recommended method of backing up a master server, since
it will backup all NIS+ directory objects that are served by
this master. If this server is a master server for more than
one domain, the backup will include NIS+ directories that
belong to all of the domains served. Individual NIS+ direc-
tory objects can be selected for restoring from a backup-
dir created with the -a option. See nisrestore(1M).
The -a option only includes directory objects for which
this server is the master. It is possible, but not recom-
mended, to configure a master server as a replica for other
domains. The objects belonging to those replicated domains
will not be backed up with the -a option. The backup of
replicated objects must be run on the master server for
those objects.
Do not use the same backup-dir to backup different master
servers. Each master server must have its own backup-dir.
nisbackup will set the rpc.nisd(1M) to read only mode,
which will disable updates to the NIS+ database. This is
neccessary to ensure the consistency of the backup. For
this reason, nisbackup should not be run while large numbers
of updates are being applied to the NIS+ database. Update
utilities such as nisaddent(1M) should not be run simul-
taneously with nisbackup.
OPTIONS
-a Creates a backup of all NIS+ directory objects for
which this server is a master.
-v Verbose option. Additional output will be produced and
sent to syslog(3C) upon execution of the command (see
syslog.conf(4)).
OPERANDS
backup-dir
The directory into which the subdirectories containing
the backed up objects are placed. This must be
created prior to running nisbackup.
directory
The NIS+ directory object(s) being backed up.
EXAMPLES
Example 1: Backup of the org_dir NIS+ directory object of
the domain foo.com on a master server to a directory named
/backup
To backup the org_dir NIS+ directory object of the domain
foo.com on a master server to a directory named /backup:
master_server# nisbackup /backup org_dir.foo.com.
Example 2: Backup of the entire NIS+ domain foo.com to a
directory named /backup
To backup the entire NIS+ domain foo.com to a directory
named /backup:
master_server# nisbackup /backup foo.com. \
org_dir.foo.com. groups_dir.foo.com. \
ctx_dir.foo.com.
Example 3: Backup of an entire NIS+ database to a backup
directory named /backup
To backup an entire NIS+ database to a backup directory
named /backup:
master_server# nisbackup -a /backup
EXIT STATUS
0 Successful completion.
1 An error occurred.

NOTES
NIS+ might not be supported in future releases of the
SolarisTM Operating Environment. Tools to aid the migration
from NIS+ to LDAP are available in the Solaris 9 operating
environment. For more information, visit
