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

fssnap(1M)						  System Administration Commands						fssnap(1M)

NAME

       fssnap - create temporary snapshots of a file system

SYNOPSIS

       fssnap [-F FSType] [-V] -o special_options /mount/point

       fssnap  -d [-F  FSType] [-V] /mount/point | dev

       fssnap -i [-F FSType] [-V] [-o special_options] [/mount/point | dev]

DESCRIPTION

       The  fssnap  command creates a stable, read-only snapshot of a file system when given either an active mount point or a special device con-
       taining a mounted file system, as in the first form of the synopsis. A snapshot is a temporary image of a file system intended  for  backup
       operations.

       While the snapshot file system is stable and consistent, an application updating files when the snapshot is created might leave these files
       in an internally inconsistent, truncated, or otherwise unusable state. In such a case, the snapshot will contain these partially written or
       corrupted files.  It is a good idea to ensure active applications are suspended or checkpointed and their associated files are also consis-
       tent during snapshot creation.

       File access times are not updated while the snapshot is being created.

       A path to the virtual device that contains this snapshot is printed to standard output when a snapshot is created.

OPTIONS

       The following options are supported:

       -d		       Deletes the snapshot associated with the given file system.

       -F FSType	       Specifies the file system type to be used. The FSType should either be specified here or be determined by  matching
			       the block special device with an entry in the /etc/vfstab table, or by consulting /etc/default/fs.

       -i		       Displays  the  state of any given FSType snapshot. If a mount-point or device is not given, a list of all snapshots
			       on the system is displayed. When a mount-point or device is specified, detailed information  is	provided  for  the
			       specified file system snapshot by default. The format and meaning of this information is file-system dependent. See
			       the FSType-specific fssnap man page for details.

       -o special_options      See the FSType-specific man page for fssnap.

       -V		       Echoes the complete command line, but does not execute the command.

OPERANDS

       The following operands are supported:

       /mount/point	       The directory where the file system resides.

EXAMPLES

       See FSType-specific man pages for examples.

EXIT STATUS

       The following exit values are returned:

       0	Successful completion.

       >0	An error occurred.

FILES

       /etc/vfstab	       Specifies file system type.

       /etc/default/fs	       Specifies the default local file system type.
