Shadow Copies

[ajbritton]

I'm thinking of enabling ShadowCopies on a volume, but I will have to host the copies on the same volume (not best practice). Assuming I do not limit the storage space available to ShadowCopies, what happens when the disk fills up. Will old ShadowCopies be deleted to make more space for user data, or will the disk appear full?

Old copies are overwritten depending on age. A 250 GB drive should suffice for all of your needs.

If you want to host shadow copy on another volume, you'll have to invest in Microsoft Data Protection Manager www.microsoft.com/dpm
Its kind of shadow copies big brother, used for disk based backup and remote storage.

Although straight after posting that I realise that I could be wrong!

Disk will appear full and old copies will 'expire' to make room for new ones.

Are you sure about that? Although I've not tried it, it looks quite simple via the interface build into Win2K3 to store shadow copies on another volume??

[ajbritton]

I just tried this on a Win2K3 server with a C: and D: volume. As a test, I configured ShadowCopies on D: volume, using a storage area on C:. It appeared to work fine.

Indeed, its best practice to put shadow copies on a seperate drive for performance reasons.

Google found me this:

Yep- you should really place the shadow copies on a separate drive/volume (Just the same as RIS etc too). We tried shadow copies at the start of the year to replace our ailing "Recovery Manager" server (CSE supplied) and it didn't work. I'm guessing a policy somewhere was stopping it- but I can't find anything referencing it.

Anyone have any ideas?

remeber there's a client side msi you need to deploy as well!

[ajbritton]

@Kingswood: Why would I need to put RIS on a different volume? Not for SIS, as this now only works on the 'REMINST' folders.

@Geoff: Thanks Geoff. I'm XP SP2 all the way, which already has the SC client included.

Anyone know how ShadowCopies gets on with Exchange / SQL server?
