The following page describes the agent-specific restore options. Additional restore options are accessible from the Related Topics menu.
ONTAP SnapVault for the Quick Recovery Agent and OSSV SnapVault for the Quick Recovery Agent
allow you perform the following types of restore operations:
- File Level Restore - You can browse the files/folders in your SnapVault
Snapshots and Replicas 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.
Before performing any restore procedures for SnapVault products, review the following
information:
- For OSSV SnapVault, the OSSV Client must be
added to the NDMP Server list in order to perform restore operations.
- For OSSV SnapVault on Unix, only
CXBF configured volumes
are available for restore in
Restore
Options.
- 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 SnapVault products.
Snapshots/Replicas 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.
By default, SnapVault products for the Quick Recovery Agent
restore 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 SnapVault for the Quick Recovery Agent and OSSV SnapVault for the Quick Recovery Agent. See Restore/Recover/Retrieve Destinations - Support for a list of Agents
supporting each restore destination type.
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.
