warning message on last nights tape backup

Veeam Logoby B2r2 » Wed Dec 13, 2017 11:18 am

Hi

Not sure if I need to open a support case with Veeam about this as it may not be a problem.

My last night file backup to tape, which read and transferred all data has the following warning message on it: -
Volume E: has 14 problems. Details: The handle is invalid.

Can anyone advice on this?

Thanks

Hi Ignacio. Is there any chance you include system directories such as C:\Windows\System32 to your file to tape job?

Hi lyapkost,

I included the directory c:/windows/system32 to different tape jobs, but the problem is the same. In some cases there are more problems.

Volume C: has 10 problem. Details: The handle is invalid.
Volume C: has 195 problem. Details: The handle is invalid.
Volume C: has 175 problem. Details: The handle is invalid.

Hey Ignacio,

Most of the time this is either access denied issues or temp files that got enumerated by the job but were later no longer present. (Like Word ~Wordfile.docx files).

You could do some self-investigation in the job logs for the warning message and see exactly what is causing problems.

That is correct, the warning is displayed when the file is unreadable for any reason or contains some Unicode characters in name. One can check which files caused warnings in logs: C:\ProgramData\Veeam\Backup\tape_job_name\Task.hostname.log

Also I can explain my question and the warning when system files are backed by file to tape job in 64-bit Windows. The process that collects the hierarchy is a 32-bit process (Veeam Installer Service) meanwhile the Veeam data mover which reads and transfers the files is a 64-bit process. When a 32-bit process tries to read files in C:\Windows\System32 directory, Windows redirects it to to C:\Windows\SysWOW64 where the files are actually located so Installer Service 'thinks' the files are there. But a 64-bit process cannot find these files in C:\Windows\System32 directory and is not redirected, as a result you receive a warning.
