NAME

xbackup − performs backup functions

SYNOPSIS

xbackup [-t] [-p | -c | -f <files> | -u "<user1> [user2]"] -d <device>
xbackup -h

DESCRIPTION

-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.  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 (i.e., ∗, .) by the shell.  The argument must be in quotes. 

-l backup local file systems only.  The default is to backup all file systems, both local and remote. 

-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 there 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 /dev/rmt/ctape1. 

-t used when the device is a tape.  This option must be used with the -d option when the tape device is specified. 

-p used to specify a partial backup.  A complete backup must be done before an incremental backup is made.  The partial backup is always based on the date of the last backup whether complete or partial. 

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, and will prompt the user when it is ready for the next medium.  The program will give you the estimated size in megabytes of how much media will be needed to complete the backup.  Tapes do not need to be formatted, but should be rewound before being used.  A data file, /etc/xBackup, if present on the system, is used by the program to determine which directories or files (specified one per line) should be backed up unconditionally.  It will override the default setting, which is to up everything on the system. Another file, /etc/xIgnore, if present on the system, is used by the program to determine which directories or files should be ignored by the backup (NOTE: /proc is automatically ignored by the program, and does not need to be included in /etc/xIgnore). The use of these data files applies to both complete and incremental backups.  The files will be referenced by the program only if they exist.
