How to ...Back Up with ufsdump (across a network)

Performing a ufsdump across a network may cause network degradation. Check with

your network administrator first prior to attempting the backup.

Files can be backed from one machine in a network to a devices else-

where in network.

1. Follow step 1. through step 4. Place the media into the drive of the

machine that will store the backups. Access the Command Tool on

the machine containing the files to be backed up.

2. Enter the ufsdump command, using the following syntax:

ufsdump <options>f <machine:device> <files_to_dump>

where <options> is a single string of one-letter options (of which f must be used

for network backup), <machine:device> represents the name of the machine and

the device ID on that machine where the files are to be dumped, and

<files_to_dump> specifies either the files, directories, or an entire file system to

back up.

Since ufsdump is normally run by root, the name of the local machine must appear

in the /.rhosts file of the remote machine. The f argument can also be specified as

user@machine:device, in which case ufsdump attempts to execute as the

specified user on the remote machine. In this case, the specified user must have a

.rhosts file on the remote machine, which allows the user invoking the command

from the local machine to access the remote machine.

There are several important options that should be considered when using

ufsdump. The following are not the only options, but can be considered

the most important from the standpoint of backing up Media Processing

Server Series-related information:

Option <argument> Definition

0-9 Dump level of files. This can be used for comparative

purposes during multiple or incremental dumps. A level 0

dump copies the entire file system to the dump file

destination media.

a <filename> Archive file. Creates a dump table of contents in the backup

(archive) file, the name of which must be specified. This

table of contents can later be used by ufsrestore to

determine whether or not a file or directory exists on the

backup. If this option is not used, ufsrestore can still read

the contents of the backup directly from the media rather

than the archive file. It is highly suggested that only Field

Engineers use ufsrestore.
