Full Discussion: Problem with ufsdump
Operating Systems Solaris Problem with ufsdump Post 302312664 by choogendyk on Saturday 2nd of May 2009 02:20:39 PM

I'm a little puzzled by the combination of the command you used and the error message you claim. The use of the f option followed by the argument /backup would indicate that you are wanting ufsdump to send its output to the "file" /backup. But, your description indicates that you were intending it to go to another disk, which would imply that /backup is a directory and is the mount point for the other disk/partition. If so, that would be wrong. It should be /backup/todays-backup, where todays-backup is the name of the file you want it to send the backup stream to.

If you tried this a couple of times, once with a directory /dump, and your server were sun1, then I could imagine an error message referring to that. Otherwise, I have trouble figuring out where the "sun1/dump" came from.

Also, the u option will be useless if /var is part of the root partition. /etc/dumpdates is only updated if you backup a complete partition. If you select directories or files within a partition to be backed up, then you get a full backup of those directories or files, and you do not get /etc/dumpdates updated.

backup_help

BACKUP_HELP(8)						       AFS Command Reference						    BACKUP_HELP(8)

NAME

       backup_help - Displays help for backup commands

SYNOPSIS

       backup help [-topic <help string>+] [-admin] [-help]

       backup h [-t <help string>+] [-a] [-h]

DESCRIPTION

       The backup help command displays the complete online help entry (short description and syntax statement) for each operation code specified
       by the -topic argument. If the -topic argument is omitted, the output includes the first line (name and short description) of the online
       help entry for every backup command.

       To list every backup command whose name or short description includes a specified keyword, use the backup apropos command.

OPTIONS

       -topic <help string>+
	   Indicates each command for which to display the complete online help entry. Omit the backup part of the command name, providing only
	   the operation code (for example, specify dump, not backup dump). If this argument is omitted, the output briefly describes every backup
	   command.

       -help
	   Prints the online help for this command. All other valid options are ignored.

OUTPUT

       The online help entry for each backup command consists of the following two or three lines:

       o   The first line names the command and briefly describes its function.

       o   The second line lists aliases for the command, if any.

       o   The final line, which begins with the string "Usage", lists the command's options in the prescribed order. Online help entries use the
	   same symbols (for example, brackets) as the reference pages in this document.

EXAMPLES

       The following example displays the online help entry for the backup dump command:

	  % backup help dump
	  backup dump: start dump
	  Usage: backup dump -volumeset <volume set name> -dump <dump level name>
	  [-portoffset <TC port offset>]  [-at <Date/time to start dump>+]
	  [-append]  [-n]  [-file <load file>]	[-help]
