Directory Quotas Features

SpaceGuard SRM Directory Quotas Features

SpaceGuard SRM is a completely new product, built from the ground up for Windows 2003-XP-2000-NT environments.  SpaceGuard SRM has all the features of SpaceGuard 4.2, and many significant enhancements and features, such as enhanced auto-add quotas, configurable disk quota policies, more notifications, unlimited disk quota levels, a brand-new interface and dramatic improvements in engine performance.

Directory Quotas

• Automatic home directory matching based on Active Directory
• Quota limits based on percentage of disk/directory size
• Configurable quota policies; save your configuration in a policy for rapid deployment and propagation
• Directory based quotas
• Quota enforcement; the engine can automatically revoke write access priviliges for a user or a group of users when a revoke access limit has been exceeded
• Unlimited disk quota levels; assign multiple limits on a disk quota to gradually escalate notifications and ultimately enforce the disk quota by revoking write access
• Auto-Add quotas; the SpaceGuard SRM engine monitors the file system for changes and automatically applies the appropriate disk quota settings

Auto-Add quotas:

An Auto-Add disk quota removes the need to add a disk quota each time a directory is added.  Each time a directory is created (inside a specified directory) a quota is set on that directory using a predefined policy or custom sizes/limits.  The SpaceGuard SRM service continuously scans the local computer's file system for directory changes.  If a new subfolder is created under the branch where the Auto-Add disk quota is active, SpaceGuard SRM automatically creates a new quota according to the Auto-Add policy.  Also, whenever subfolders under an Auto-Add quota root are removed, the related quota is also removed automatically.  This is extemely useful for large and rapidly changing home directory shares.  Each time a new home folder inside for example G:\UserData is created, you want each home directory to get a 50MB disk quota with a standard size and limit policy.  All you have to do is create an Auto-Add quota on G:\UserData, customise the sizes and limits, and notice how SpaceGuard SRM creates all quota's automatically.  

Unlimited quota levels:

Each disk quota can have one or more limits.  A limit is a percentage based on the disk quota size.  If you have for example a fixed disk quota size of 50MB and you define a limit of 100% and assign an alert, the alert will be executed when the 50MB has been exceeded.  This way, you can assign multiple limits to a single quota, for instance:
Fixed disk quota size, 50MB:
Limit 1: 80%, send a popup to the user assigned to the quota.  (executed at 40MB)
Limit 2: 90%, send a popup to the administrator.  (executed at 45MB)
Limit 3: 100%, revoke the write access of the user assigned to the quota.  (exectued at 50MB)
