Hi,
We are currently doing some netapp snapdiff backups and we saw that they perform very badly .
I have used a small powershell cli to see how long it takes to dir/file scan a cifs share between a phy Windows Server share and a Netapp share . The result have been here that the Netapp is about 4 times slower. ( our Netapp Sample is : 25K Files in about 40 Sec, vs 10 Sec on the Windows Server - ofc same source )
I know we get the diff by snapdiff. But we would also like/maybe do a full increment monthly to 1. be sure and 2. to update the fs date last Backup .
net use \\netapp\share$
cd \\netapp\share$
date;(Get-ChildItem -Recurse | Measure-Object).Count;date
Anyone with a NetApp in place who is willing to try , and post results ? Would recommend using a share with 30K Files max.
Thx, Dietmar
