ity
SYNOPSIS
/opt/VRTS/bin/fsckpt_restore [ -n | -y ] [ -l ] device_name [ ckpt_name
]
AVAILABILITY
VRTSvxfs
DESCRIPTIONfsckpt_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.
