Disk Changes

[bertieuk]

Hi
After some guidance.

I'm working on a SAN project which includes Snapshots but I need to try and work out how large to make each snapshot volume.

Does anyone know if it possible to monitor disk changes using VBS at a disk block level. I could get a simple view by taking a daily incremental backup but I dont think that this will give me a true physical disk change.

Thanks
Si

A starting point:
Dim drvPath, fso, d, s
drvPath = "//server/path"
Set fso = CreateObject("Scripting.FileSystemObject")
Set d = fso.GetDrive(fso.GetDriveName(drvPath))
s = "Drive " & UCase(drvPath) & " - "
s = s & d.VolumeName & vbCrLf
s = s & "Total Size: " & FormatNumber(d.TotalSize / 1024, 0) & " Kbytes" & vbCrLf
s = s & "Free Space: " & FormatNumber(d.FreeSpace / 1024, 0) & " Kbytes"
MsgBox s


Hope This Helps, PH.

Just looking this over, it would seem that the script would give free space and total space. What I'm actually after would be an indication of changing data at a block level i.e. If a 10GB file has only a 1 byte change then only measure the block size containing the 1 byte.

Thanks
