Backup(1)							     Backup(1)

NAME    [Toc]    [Back]

     Backup - backup the specified file	or directory

SYNOPSIS    [Toc]    [Back]

     Backup [ -h hostname ] [ -i ] [ -t	tapedevice ]
	  [ directory_name | file_name ]

DESCRIPTION    [Toc]    [Back]

     The Backup	command	archives the named file	or directory (the current
     directory if none is specified) to	the local or remote tape device.  It
     can be used to make a full	system backup by specifying the	directory name
     as	/.

     In	case of	a full backup, this command makes a list of the	files in the
     disk volume header	and saves this information in a	file which is then
     stored on tape.  This file	is used	during crash recovery to restore a
     damaged volume header.  Information about mounted filesystems and logical
     volumes is	also copied to the backup.  The	current	date is	saved in the
     file /etc/lastbackup.

     Full system backups can be	used with the system recovery mechanism	from
     the PROM maintenance mode (the miniroot is	booted with mode 3 in the
     normal way, but recovery is started, instead of installation).  See your
     Owner's Manual for	more information on this procedure.

     The options and arguments to Backup are:

     -h	hostname     If	a tape drive attached to a remote host is used for
		     backup, specify the name of the remote host with the -h
		     hostname option.  For remote backup to successfully work,
		     you should	have a TCP/IP network connection to the	remote
		     host and guest login privileges on	that host.

     -i		     If	a backup of all	files modified since the date
		     specified in the /etc/lastbackup file is desired, specify
		     the -i option.  This option is valid only when doing a
		     complete backup.

     -t	tapedevice   If	the local or remote tape device	is pointed to by a
		     device file other than /dev/tape, specify the device with
		     the -t tapedevice option.

     directory_name  Create a backup of	the directory directory_name.  For
		     this case,	when files are restored, they will be restored
		     in	the root directory, with the leading directory_name
		     stripped off.

     file_name	     Create a backup of	the file file_name.

     The Backup	command	uses cpio(1) to	perform	the backup function.  Older
     versions used bru(1), or tar(1).  The Restore(1) command will handle any
     of	the 3 types of backups.

FILES    [Toc]    [Back]

     /tmp/volhdrlist	 contains the list of the root volume header files
     /etc/lastbackup	 contains the date of last full	backup for incremental
			 backups; the modification time	of this	file is	used

NOTE    [Toc]    [Back]

     Backup constructs a list of file names with find to pipe to cpio.
     Filenames with embedded white space will work this	way, with the
     exception of filenames with embedded newlines, since each filename	in the
     list is terminated	by a newline.  This may	sometimes produce confusing
     error messages.

     The exit status is	0 on success (including	the case where no files	are
     backed up,	but no errors with the tape drive or command occur).

NAME    [Toc]    [Back]

     backup - backup files and directories now,	later, or recurring

SYNOPSIS    [Toc]    [Back]

     /usr/sysadm/privbin/backup	-f device -n [ options ]
     /usr/sysadm/privbin/backup	-f device -l time [ options ]
     /usr/sysadm/privbin/backup	-f device -d time [ options ]
     /usr/sysadm/privbin/backup	-f device -w day:time [	options	]

DESCRIPTION    [Toc]    [Back]

     backup is a privileged command that performs a backup of the entire
     system or of a selected list of files.  The backup	can be performed now,
     once at a later date, or recurring	either daily or	weekly.

     backup uses cpio(1) to write its output.  device would typically be a
     tape device, but can also be a file for backing up	to disk.

     -n	is used	to specify that	a backup occur now, -l is for backups which
     are occur once at a later date, -d	is for daily backups, and -w is	for
     weekly backups.  Backups that occur once at a later date are scheduled
     using at(1), and recurring	backups	are scheduled using cron(1).

     After scheduling a	later or recurring backup, backup prints to its	output
     a string which uniquely identifies	this backup to the system.  This
     string can	be used	to unschedule the backup using unschedBackup(1M).

     backup can	be run by ordinary users without going through runpriv(1M).
     Ordinary users cannot do full system backups, and backups made by
     ordinary users will not be	able to	back up	files that the user does not
     have permission to	read.

     When doing	a full system backup, backup does not back up nfs mounted
     files.  When backing up a selected	list of	files, backup does back	up nfs
     mounted files.

OPTIONS    [Toc]    [Back]

     -f	device Specifies where the backup is to	be written.  Typically this
	       would be	a tape device such as /dev/tape	or
	       user@remotehost:/dev/tape, but can also be a file for backup to

     -n	       Specifies that the backup is to occur now.

     -l	time   Specifies that the backup is to occur at	time.  time is in
	       seconds since midnight Jan 1, 1970.

     -d	time   Specifies that the backup is to occur daily.  time is the
	       number of seconds after midnight	to start the backup.

     -w	day:time
	       Specifies that the backup is to occur weekly.  day is the
	       number of days after after Sunday to start the backup, and time

	       is the number of	seconds	after midnight to start	the backup.

     -i	indentifier
	       identifier is to	be associated with this	backup.	 identifier is
	       displayed in the	BackupAndRestoreManager(1M) along with the
	       icon for	this backup.

     -v	       Output of the backup is to be verbose.  Specifying -v to	backup
	       causes v	to be included as an option to cpio(1).

     -m	email-address
	       For later and recurring backups,	send a backup report to
	       email-address.  If -v was specified, this will include a	list
	       of the files which were backed up.  If this option is not
	       specified, the user that	scheduled the backup will receive mail
	       from cron.

     -s	source source is a file	containing a list of files to be backed	up,
	       one per line.  These can	either be full paths, or can be
	       relative	to the root specified with the -r option.  If the -s
	       option is not specified,	this will be a full system backup.

     -r	root   Specify that the	backup should be relative to root.  This has
	       no effect unless	the paths in source are	relative, and never
	       has an effect on	full backups.

FILES    [Toc]    [Back]

     /var/sysadm/backups/*    File lists for later and recurring backups
			      scheduled	by root.
     $HOME/.saBackupLists/*   File lists for later and recurring backups
			      scheduled	by non-root users.
     $HOME/.saBackupSched/*   Information about	later backups for the
			      BackupAndRestoreManager(1M).  This duplicates
			      information stored by at(1) which	is not
			      readable by non-root users and difficult to
			      parse.  Information about	recurring backups is
			      retrieved	using crontab(1).
