NAME
     fssnap - create temporary snapshots of a file system

SYNOPSIS
     /usr/sbin/fssnap [ -F FSType ]  [ -V ]   -o  special_options
     [ mount-point  | special  ]

     /usr/sbin/fssnap   -d   [  -F   FSType  ]   [   -V   ]    -o
     special_options  [ mount-point  | special  ]

     /usr/sbin/fssnap  -i   [  -F  FSType   ]    [   -V   ]    -o
     special_options  [ mount-point | special ]

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 containing 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.

     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.
