You can restore a range of data from a file in a Snapshot copy to an existing file in the active file system. Partial file restores can only be used to restore specific pieces of a LUN, and NFS or CIFS container files.
Before you begin
- You must understand the metadata of the host LUN or container file so that you know which bytes belong to the object that you want to restore.
- The volume where the LUN or the container file is to be restored must be online and writeable.
About this task
Write operations are not allowed on the object that you are restoring; otherwise, it might result in inconsistent data.
- Restore part of a file by using the volume snapshot partial-restore-file command.
To get the settings for partial file restore on a cluster, use the volume snapshot partial-restore-file-list-info command.
- After the restore is complete, purge operating system or application buffers so that the stale data is cleaned.
