Restore SQL ERROR

Hello Everybody

My SQL DBA show me a error that occurs when he performs a Netbackup SQL restore.

BackupIoRequest::WaitForIoCompletion: read failure on backup device 'VNBU0-5420-2608-1384455034'. Operating system error 995(The I/O operation has been aborted because of either a thread exit or an application request.).

Anyone knows what this error means? Is this a Netbackup backups problem?

Thanks
