zfs.roll.snapshot
This script will create (or recreate, if it already exists) a ZFS snapshot, and then use the ZFS "clone" functionality to automatically mount the snapshot in an alternate location. This process prevents you from having to point the backup software at a .zfs/snapshot directory, which is clumsy.By default the script will mount the clone under /zbackup, although this behavior can be changed with options or by editing the script. Because a ZFS clone is created using the same type of copy-on-write pointers as the snapshot itself, it uses additional space only when data changes in the live volume.Read BigAdmin article that describes usage of this script: http://www.sun.com/bigadmin/content/...apshot_zfs.jsp

bb-snapshot.cgi

BB-SNAPSHOT.CGI(1)					      General Commands Manual						BB-SNAPSHOT.CGI(1)

NAME

       bb-snapshot.cgi - CGI program to rebuild the Xymon webpages for a specific point in time.

SYNOPSIS

       bb-snapshot.cgi

DESCRIPTION

       bb-snapshot.cgi	is  invoked as a CGI script via the bb-snapshot.sh CGI wrapper.  It rebuilds the Xymon web pages to the look they had at a
       particular point in time, based upon the historical information logged about events.

       bb-snapshot.cgi is passed a QUERY_STRING environment variable with the following parameters:

	  mon (Start month of the snapshot)
	  day (Start day-of-month of the snapshot)
	  yr  (Start year of the snapshot)
	  hour (Start hour of the snapshot)
	  min  (Start minute of the snapshot)
	  sec  (Start second of the snapshot)

       The "month" parameters must be specified as the three-letter english month name abbreviation: Jan, Feb, Mar ...

       "day" must be in the range 1..31; "yr" must be specified including century (e.g. "2003"). "hour" must be specified using a 24-hour clock.

       All of the processing involved in generating the report is done by invoking bbgen(1) with the proper "--snapshot" option.

OPTIONS

       --env=FILENAME
	      Load environment from FILENAME before executing the CGI.

       bbgen-options
	      All options except "--env" are passed on to the bbgen(1) program building the snapshot files.

ENVIRONMENT VARIABLES

       BBGENSNAPOPTS
	      bbgen options passed by default to the bb-snapshot.cgi script.  This happens in the bb-snapshot.sh CGI wrapper script.

       BBHOME Home directory of the Xymon server files

       BBSNAP Directory where generated snapshots are stored. This directory must be writable by the userid executing the  CGI	script,  typically
	      "www", "apache" or "nobody". Default: $BBHOME/www/snap/

       BBSNAPURL
	      The URL prefix to use when accessing the reports via a browser.  Default: $BBWEB/snap
