Limitations
Cross-platform recovery operation of individual files is not supported. You can restore windows files only on windows guest operating systems and Linux files to only supported Linux guest operating. That implies, the recovery host must be the same platform as the files that you want to restore.
In a recovery process, NetBackup recreates the links between a hard link and its original file. Only in this case, the link file, and its target file must be restored in the same job.
Note:
If each file is restored individually in separate restore jobs, they are restored as separate files and the link is not re-established.
For dual-boot virtual machines, NetBackup does not support recovery of individual files or folders.
For client platform and file system support and limitations, see https://www.veritas.com/content/support/en_US/doc/NB_70_80_VE .
The Flatten existing directory structure and Append string to file names options are only applicable to files. They are not available for directories.
If you select and Overwrite existing filesoptions, you risk an incorrect restore, if it contains multiple files with the same file name.
Note:
The last restored file is available, when the restore completes.
If you select the option but do not select , the restore succeeds, but the first file that is restored is present when the restore completes. To prevent, do not select when restoring multiple files with the same name.
If a backup and a restore occur simultaneously on the same VM, one or both jobs can have unexpected results.
Note:
If a backup or a restore exits with a non-zero NetBackup Status Code, one possible cause is simultaneous jobs occurring on the same VM.
If selected restore data contains any hidden files such as
.bashrc,.bash_history, Append string to file names restore option is not supported.Nutanix agentless restores can only be used to the restore of files and folders.
Restore job fails, if NetBackup does not have sufficient privileges to the staging directory or if there is insufficient space in the staging directory.
Note:
Veritas does not recommend Nutanix AHV agentless restore, if a NetBackup client already exists on the target VM. The NetBackup administrator must use the agent-based restore in such cases.
On windows target host, restore destination to a mapped drive, is not supported.
NetBackup does not support the communication with windows target host with a use of
openSSH. In such cases restore job fails.NetBackup does not support non-ASCII characters in target host staging-location path.
NetBackup only supports NTLM authentication type for windows target host.
AHV images backed-up before 9.1 release, cannot be restored from web UI. To restore these images user must use NetBackup Administration Console.
AHV backup images are available on web UI, even if the backup was taken from NetBackup Administration Console provided the backup host has NetBackup version 9.1 or later.
About the backup images on web UI:
If the asset discovery is successful, and after that backup is taken from NetBackup Administration Console, backup images are available on web UI.
If the primary sever and backup host are upgraded to 9.1, backup is taken from NetBackup Administration Console, and then if you configure web UI, you must run asset discovery to see the backup images.
If the primary sever is upgraded to 9.1 but backup host is version is still before 9.1 and backup is taken from NetBackup Administration Console. Then, if you configure web UI, you cannot see the backup images even after asset discovery.
For alternate restores, the restore operation is successful if check box is selected. However, attributes like Project, category, owner information, and VPC-related information are not restored.
If there was a network configured in VM when backup was triggered and user tries alternate restore with this backup image keeping check box not selected, then restore operation fails.
If a VM had Project configured, when the backup was triggered but the project did not exist when the restore was triggered, the restore job fails.
If a VM had Category configured, when the backup was triggered but the category did not exist when the restore was triggered, the restore job fails.
If VM's user is not present in the Prism Central server or in Project at the time of restore, then restore operation fail.
Only IP addresses with type ASSIGNED is considered for restore. Learned IP type is ignored and user must manually configure the IP after restore.
If the VM has NIC with span port enabled, then after restore this is ignored. You must manually add and configure span on the NIC with Nutanix CLI.
A VM is restored with Project, Category, Owner details, and other VPC-related attributes, if the original location restore has been performed.
An undefined behavior is observed when trying to backup/restore the VM's of a cluster which have been moved from one Prism Central to another.
A backup host with version 10.1.1 or later is required to backup/restore project, category and other Virtual Private Cloud (VPC) related attributes. If a backup host with version lesser than 10.1.1 is used, backup/restore will complete without capturing VPC related attributes if a VM is not present in VPC environment. If a VM is in VPC environment and if restore is triggered through a backup host with version lesser than 10.1.1, then the restore might fail.
