I trilled to hear that, because the enigineer I had for our case with Flashbackup-windows on MSCS on windows x64 to work.

Actually I think he showed me where it said in the manual that Flashbackup-windows wasn't supported on Netbackup 6.5.1

Is a silver the same as a disk letter ? or is it a mountpoint ?

Yup - we call them slivers - a small 1GB mountpoint .

Would like to hear our experience with it, especially performance wise

It's absolutely great - we're seeing about 30MB/sec (and this varies GREATLY) on large file systems. We typically use FlashBackup to DSSU and then destage from there. It cuts our backup time in half. We use it on both Solaris and Windows 2003 x64 media servers with Windows 32-bit and 64-bit clients (as well as Solaris clients).

You'll see the performance appear to be really slow when it starts while it's mapping the file system but then it starts to pick up speed and takes off.

The biggest problem, by far, has been with Microosft VSS on the client and the sysadmins' inabilities to read their own docs and configure the clients properly.
