assuming you're talking about Shadow Copy Restore feature: - how many changes do your users make per day and how many versions of the documents do you want to keep? => this will determine the space you should calculate for each volume. Add 105 MB, which is what the feature requires for itself.
- how much extra fault-tolerance do you need? you don't need to put the previous versions data on a particular safe disk => could also be RAID 0 or separte disks. /Guido -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ellis, Debbie Sent: Tuesday, October 19, 2004 1:12 PM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] Shadow Copy Is there any formula for figuring out how much hard drive space you will need ? Also which is better, Raid 5 or mirror sets for Shadow Copy?

I've been using it for a year now wo any problems. I store all the snapshots on a dedicated set of mirrored drives. Between shadow copy and a long retention time for undelete, I have't restored anything from tape in a very long time.
