NAME
backup - (XENIX) perform backup functions
SYNOPSIS
backup [-t] [-p | -c | -f files | -u "user1 [user2]"] -d device
backup -h
DESCRIPTION
The backup command performs backup operations. It accepts the
following options:
-h produces a history of backups. Tells the user when the
last complete and incremental/partial backups were done.
-c complete backup. All files changed since the system was
installed are backed up.
-p partial backup. If an incremental/partial backup was
done, all files modified since that time are backed up.
Otherwise all files modified since the last complete
backup are backed up. A complete backup must be done
before a partial backup.
-f backup files specified by the files argument. file
names may contain characters to be expanded (that is, *,
.) by the shell. The argument must be in quotes.
-u backup a user's home directory. All files in the user's
home directory will be backed up. At least one user
must be specified but it can be more. The argument must
be in quotes if more than one user is specified. If the
user name is "all", then all the user's home directories
will be backed up.
-d used to specify the device to be used. It defaults to a
machine-specific value.
-t used when the device is a tape. This option must be
used with the -d option when the tape device is
specified.
A complete backup must be done before a partial backup can be
done. Raw devices rather than block devices should always be
used. The program can handle multi-volume backups. The
program will prompt the user when it is ready for the next
medium. The program will give you an estimated number of

floppies/tapes that will be needed to do the backup. Floppies
must be formatted before the backup is done. Tapes do not
need to be formatted. If backup is done to tape, the tape
must be rewound.
