RE: move data within CIFS

Using robocopy on any server will grant that all the data is transferred via LAN. And it has a lot of options like purge and mir, but it can never move data within a partition without really transferring them. A move within the same drive letter on a windows server will take less than a second because only the MFT is changed and no block of real data transfered.

If we would run this from an external server we would have to use plink. But the server would have to read the structure to know what to tell plink. With tens or hundreds of thousand small files this would take presumably more time than to copy them directly. With kind regards.

Maybe you'll have to change the privilege mode to advanced or diag. I you've any doubt during the real m€ove take a snapshot before proceeding to be able to quicky restore in case of problem _________________ Michael Bernardoff FSE@netapp +33 679 028 224 -----Original Message----- From: Knut Kristan Weber k.weber@science-computing.de To: toasters@mathworks.com toasters@mathworks.com CC: winserver-team@science-computing.de winserver-team@science-computing.de Sent: Fri Feb 29 09:20:22 2008 Subject: move data within CIFS Hello *, we have a NetApp working as a CIFS-Filer. A collegue wants to move about 6 TB of data in the directory scruture one level up within the same volume. Using the filer with a LUN as a block device would work like this. A normal windows Server also can move data in between the same drive letter without copying it - just in a scond. But the NetApp has no solution I know so far to make a move when it works itwself as a CIFS filer. And even worse it does not only cost disk space because it copies and deletes afterwards, but also all the 6 TB data move over the LAN. Is there something like a move in advanced mode or any undocumented ways? Or to use NDMP copy in such a way? thanks a lot in advance ------------------------------------------------------------ with kind regards ______________________________________creating IT solutions Dipl.-Chem.
