[hsatapat@app-test .snapshot]$

You can restore the snapshot

You can restore a file within the snapshot, or an entire snapshot using the cp command. Use the -r option when restoring a snapshot that contains subdirectories.

For example: Copy

[hsatapat@app-test .snapshot]$ cp -r .snapshot/snapshot-Jan28/* /u01/install/APPS

cp -r .snapshot/snapshot_name/* destination_directory_name

For optimal performance, use the Parallel File Tools

To install Parallel File Tools on an Oracle Linux instance:

  1. Open a terminal window on the destination instance.
  2. Type the following command:
    • sudo yum install -y fss-parallel-tools

Optionally, you can use rsynctar, or another tool that supports NFSv3 to copy your data to another remote location.

For example: 

parcp .snapshot/snapshot_name/* destination_directory_name
