Application Information - N/A


Description:
This article describes the situation whereby relocating files for restore to another machine other than the source machine, produces a 42-byte overhead per file on the destination system.


Symptoms:
NetVault appears to be adding a 42-byte additional metadata information on files that are:
- relocated from the source system
- restored to another machine
This has been reported on all Plateforms and all NetVault version, only when the source server's File System Version is different from the target server's File System plugin version.
Since the receiving system has a different File System plugin, the files cannot simply be restored to their exact original state. The integrity of the files is not a problem but this could severely impact the destination system in terms of storage availability or occuppancy. In the event of limited space on the destination AND numerous files being restored, the receiving system disk could be filled and result in lack of space on this machine.
