Restoring a single file, LUN, or NVMe namespace from a SnapMirror destination

You can restore a single file, LUN, a set of files or LUNs from a Snapshot copy, or an NVMe namespace from a SnapMirror destination volume. Starting with ONTAP 9.7, you can also restore NVMe namespaces from a SnapMirror Synchronous destination. You can restore files to the original source volume or to a different volume.

Before you begin

To restore a file or LUN from a SnapMirror Synchronous destination (supported starting with ONTAP 9.5), you must first delete and release the relationship.

About this task

The volume to which you are restoring files or LUNs (the destination volume) must be a read-write volume:

Procedure

  1. List the Snapshot copies in the destination volume:volume snapshot show -vserver SVM -volume volume
    For complete command syntax, see the man page.
    The following example shows the Snapshot copies on the vserverB:secondary1 destination:
    cluster_dst::> volume snapshot show -vserver vserverB -volume secondary1

  2. Restore a single file or LUN or a set of files or LUNs from a Snapshot copy in a SnapMirror destination volume: snapmirror restore -source-path SVM:volume|cluster://SVM/volume, ... -destination-path SVM:volume|cluster://SVM/volume, ... -source-snapshot snapshot -file-list source_file_path,@destination_file_path
    For complete command syntax, see the man page.
    Note: You must run this command from the destination SVM or the destination cluster.
    The following command restores the files file1 and file2 from the Snapshot copy daily.2013-01-25_0010 in the original destination volume secondary1, to the same location in the active file system of the original source volume primary1:
    cluster_dst::> snapmirror restore -source-path vserverB:secondary1 -destination-path vserverA:primary1 -source-snapshot daily.2013-01-25_0010 -file-list /dir1/file1,/dir2/file2
    
    [Job 3479] Job is queued: snapmirror restore for the relationship with destination vserverA:primary1
    The following command restores the files file1 and file2 from the Snapshot copy daily.2013-01-25_0010 in the original destination volume secondary1, to a different location in the active file system of the original source volume primary1.

    The destination file path begins with the @ symbol followed by the path of the file from the root of the original source volume. In this example, file1 is restored to /dir1/file1.new and file2 is restored to /dir2.new/file2 on primary1:

    cluster_dst::> snapmirror restore -source-path vserverB:secondary1 -destination-path vserverA:primary1 -source-snapshot daily.2013-01-25_0010 -file-list /dir/file1,@/dir1/file1.new,/dir2/file2,@/dir2.new/file2
    
    [Job 3479] Job is queued: snapmirror restore for the relationship with destination vserverA:primary1 
    The following command restores the files file1 and file3 from the Snapshot copy daily.2013-01-25_0010 in the original destination volume secondary1, to different locations in the active file system of the original source volume primary1, and restores file2 from snap1 to the same location in the active file system of primary1.

    In this example, the file file1 is restored to /dir1/file1.new and file3 is restored to /dir3.new/file3:

    cluster_dst::> snapmirror restore -source-path vserverB:secondary1 -destination-path vserverA:primary1 -source-snapshot daily.2013-01-25_0010 -file-list /dir/file1,@/dir1/file1.new,/dir2/file2,/dir3/file3,@/dir3.new/file3
