Hi All,

 

maybe you have an idear. I have an VM wich is running under nutanix ahv. The VM has an size of 25TB with only one disc. The Backup is not the problem incr jobs running ine also synthfull is okay. 

 

But the problem is the tape out. During the single stream with 25TB the auxcopy job runs 36h 

 

Is there any possibility to increase the tape out speed. Yes more discs could be helpfull but no option more multiplexing also in idear but will be decrease the restore process.

I believe it will be limited to a 1 stream job with only 1 disk.

You may want to consider protecting it with a File System agent.

Thanks,
Scott

Hi ​@SSchmidt,

The only way I see that you could increase throughput would be to use more streams and thus more tape drives for the copy. This would mean that aux copies but also restores would use multiple tapes and drives at the same time but I am not sure if that would work for a single VM.

This should work with file system agent as that backup type does use multi-stream backup on one system.

Kind regards,

Paul

Would it be possible to have multiple data readers for a single VM disks? I also face this similar issue.
