NAME
       fsckpt_restore  - VxFS Storage Checkpoint file system restoration util‐
       ity

SYNOPSIS
       /opt/VRTS/bin/fsckpt_restore [ -n | -y ] [ -l ] device_name [ ckpt_name
       ]

AVAILABILITY
       VRTSvxfs

DESCRIPTION
       fsckpt_restore  restores	 a  VxFS  file	system	on  the	 block	device
       device_name  from   one	 of   its   Storage   Checkpoints   ckpt_name.
       fsckpt_restore  can  operate  interactively  in	a non-interactive mode
       depending on whether the -y or -n option is specified.

       device_name specifies  the  block  device  on  which  the  file	system
       resides.

       ckpt_name  specifies  the  name of the Storage Checkpoint from which to
       restore the file system. If no Storage Checkpoint  name	is  specified,
       fsckpt_restore  lists the Storage Checkpoints found, and in interactive
       mode, prompts for selection and confirmation of	a  Storage  Checkpoint
       from which to restore the file system.

NOTES
       After  restoring a Storage Checkpoint, a file system will be busy after
       it is next mounted until cleanup operations complete.  If  you  try  to
       unmount	the  file  system during this time, a file system busy message
       may be displayed.  Wait until the cleanup operations complete  and  try
       the unmount again, or do a forced unmount.

       The  name  of the Storage Checkpoint is preserved when a file system is
       restored from that Storage Checkpoint.  That is, the name of the	 Stor‐
       age  Checkpoint	is used by the fileset.	 For example, if a file system
       is restored from a Storage Checkpoint named backup1,  you  must	rename
       the  fileset if you wish to create another Storage Checkpoint using the
       name backup1.  See the fsckptadm(1M) manual  page  for  information  on
       renaming a Storage Checkpoint.

WARNINGS
       When  a	file  system  is  restored  from  a  Storage  Checkpoint using
       fsckpt_restore, all changes made to that file system after the creation
       of  the	Storage	 Checkpoint  are  permanently unrecoverable.  The only
       Storage Checkpoints and data preserved are those that were  created  at
       the same time as, or before, the selected Storage Checkpoint's creation
       time.  Run fsckpt_restore only if later changes to the file system  can
       be discarded.

       Neither	the  file  system  nor	any  of its Storage Checkpoints can be
       mounted when fsckpt_restore is invoked.

Cluster File System Issues
       No cluster issues; command operates the same on cluster file systems.

OPTIONS
       -l	 Lists information on the file system  root  and  all  of  its
		 Storage  Checkpoints.	 Typically,  fsckpt_restore lists only
		 those Storage Checkpoints which can be	 selected  as  sources
		 for file system restoration.

       -n	 Reports the dates and options for the Storage Checkpoint, but
		 does not restore the file system.

       -y	 Does not prompt for confirmation before  restoring  the  file
		 system.
