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. Beginning 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.

What you'll need

To restore a file or LUN from a SnapMirror synchronous destination (supported beginning 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:

  • SnapMirror performs an incremental restore if the source and destination volumes have a common Snapshot copy (as is typically the case when you are restoring to the original source volume).

  • Otherwise, SnapMirror performs a baseline restore, in which the specified Snapshot copy and all the data blocks it references are transferred to the destination volume.

Steps

  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

    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

    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
