WHS Refresh Storage Backup Drive Size RRS feed

    I just rebuilt with the refresh version and was wonder if there was a drive size issue. 

    I now have 2.5 Tb of data on the WHS.  Do I need to have a drive that will hold all the data or will the pool use multiple drives and backup the data to the combined drives? 

    If I remember correctly that is how WHS V1 worked but the first release of WHS V2 required that I have a drive that would hold all the data.

    Thanks,

    Glenn

    For backing up your server to external storage, Windows Home Server uses the Server Backup feature from Windows Server 2008. That uses differencing vhds to allow incremental backups, however there's a limit of 2 TB (which I believe is per share) on the amount of data you can back up to a single vhd. You can't automatically span disks with backups, so if you have more than 2 TB of data you will need some sort of hand-crafted solution. This could be as simple as multiple disks with backups configured by hand; everything you need to do it is available from the server desktop.
    I'm not on the WHS team, I just post a lot. :)

    Ken,

    That is what I thought since I didn't see anything new in the documentation.  I use the WHS backup for the server, client computers, and selected WHS folders.  I have a wbadmin job that I run throught Task Scheduler to do the other various backups.  I have dual drive cradles that I split the backup between.  It also works good for Disaster Recovery since all I need to do is grab the drives from the cradles and I have all my data.

    Thanks for your input.
