In my last post I mentioned Server 2008’s two quotas features – the old (NTFS) and the new (File Server Resource Manager, or FSRM). FSRM quotas have two features you may want to know about, both involving subfolders.
If you set an NTFS quota on a folder and a subfolder, and the subfolder quota is larger than that on the parent folder, the more restrictive quota (i.e. the parent’s) will apply. You might assume that it would be this way, but it’s not necessarily obvious, because NTFS permissions work differently. That is, you can set explicit NTFS permissions on a subfolder to be more permissive than the permissions on the parent. Not so with FSRM quotas.
The second feature is actually pretty cool. It’s called “autoquotas” and is useful if you are using folder redirection to move users’ “Documents” or “My Documents” folders to a server. When you set an autoquota on a parent folder, any subsequently created subfolders under that parent folder will assume the autoquota settings. That’s handy because otherwise you’d have to set quotas manually for newly-created user document folders.
For those of you who want to get even fancier, next time we’ll take a look at what you can do with quotas at the command prompt.
