Restore Data - ONTAP Snapshot

Overview

The following page describes the agent-specific restore options. Additional restore options are accessible from the Related Topics menu.

ONTAP Snapshot for the Quick Recovery Agent allows you perform the following types of restore operations:

  • File Level Restore - You can browse the files/folders in your snapshots and select the files/folders you want to restore.
  • Volume Level Restore - You can restore volumes you have backed up by selecting all contents for a volume; do this by selecting the top level node in the Browse window.

NOTES

The system does not allow cross-OS volume level restores.

Restore Considerations for ONTAP Snapshot

Before performing any restore procedures for ONTAP Snapshot, review the following information:

  • In the Job Controller Window, the progress indicator for restore stays at 0% until the job is finished, at which time the indicator changes to 100%. This occurs whether the job is successful or failed.
  • To restore an iSCSI snapshot volume, take the volume offline before performing the restore. Otherwise the restore will fail.
  • Application level restore does not apply to ONTAP Snapshot. Snapshots should be restored through the QR Browse window as described in the procedures below.
  • File Level Restore
    • When restoring data to a computer in a different domain:
      • If two domains have the correct trust relationship established, the ACLs will be restored to the new domain.
      • If the two domains do not have any trusts, the old ACLs cannot be restored to the new domain even if the accounts have the same names. This is because the SIDs for the name will be different in each domain, and, therefore, are not recognized.
    • If a specified destination path does not exist on the file server, the full path will be created in root. For example, if the root is /vol/vol0 and you specify vol/S3/qtree1/test as the destination path and it does not exist on the destination file server, then the files are restored under /vol/vol0/vol/S3/qtree1/test.

Restore Destinations

By default, ONTAP Snapshot for the Quick Recovery Agent restores a volume or file(s) to the client from which it originated; this is referred to as an in-place restore. If desired, you can also restore the data to a different client or file server. Keep in mind the following considerations when performing such restores:

  • The destination client must reside in the same CommCell as the client whose data was replicated.
  • Note that when you perform restores other than in-place restores, the restored data assumes the rights (i.e., permissions) of the parent directory.

The following section enumerates the types of restore destinations that are supported by ONTAP Snapshot for the Quick Recovery Agent. See Restore/Recover/Retrieve Destinations - Support for a list of Agents supporting each restore destination type.

In-Place Restore

Out-of-Place Restore

Cross-Platform Restores

Restore to Network Drive or NFS-Mounted File System

For File Level restores only, you can also Restore to a Network Drive/NFS-Mounted File System. This is similar to an out-of-place restore except that:

  • The restored data passes through the client computer to the mapped NFS mount.
  • The computer that hosts the share or mounted file system need not be another client within the CommCell.
