SpaceGuard SRM vs.  Native Windows 2000/2003 quotas

SpaceGuard SRM offers far more control over user disk space consumption than the standard native Windows 2000 and 2003 quotas.  By using directory quotas, SmartQuota technology, extensive alerting capabilities (SMS, pager, popup, email, SNMP, eventlog), quotas on NT environments and rapid deployment and configuration options, SpaceGuard SRM surpasses Windows 2000/2003 quotas in functionality, performance and ease of use.

Other features

Multiple disk quota limits
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)

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.

Configurable disk quota policies
Quota policies are used to store configuration settings such as quota size, limits and alarm actions in a single policy.  When creating quota's later on, you can use this policy for one-step deployment.  

Quota enforcement
The revoke access alarm action can be used to deny write access to the quota's directory for a single user or an entire group of users.  When linked to a certain quota limit, SpaceGuard SRM will revoke the access rights by setting explicit 'Deny' write in the directory's ACL.

When the limit is no longer exceeded, SpaceGuard SRM will revert back to the original access rights and restore the ACL including the owner to its original state.  This also happens when deleting a quota that was previously revoked by SpaceGuard SRM.

Pager and SMS alerting
The Pager-SMS alarm action can send standard formatted page and SMS messages to any compatible pager and mobile phone worldwide.  SpaceGuard SRM supports a wide range of international telecom providers to relay these messages.

Notifications

When managing a network pro-actively, it is of critical importance that administrators are notified before end-user operation is affected.  SpaceGuard's notification engine gives you total freedom and flexibility to suit your organisational needs.  

All notification methods support custom scheduling and escalation settings.  By combining multiple notifications, such as e-mail and pager and SMS you can define your own insurance policies for maximum performance, availability and security.  

1.  Popup messages
Sends a standard popup message to a computer or a user notifying the status of the incident.  The contents of popup messages can be configured using keywords containing status information.

2.  E-mail messages
Like the popup messages, e-mails can be configured to show relevant status information.  

3.  Pager and SMS messages
SpaceGuard supports sending pager and/or SMS messages to all devices and operators worldwide.  The contents of these messages can also be configured like the popup messages.  

4.  Log event
SpaceGuard can write an event to the event log of a computer, storing the status of an incident.  When integrating SpaceGuard with other applications, these applications can receive status information through these log events.  

5.  Command line, script and batch file execution
SpaceGuard can execute a batch file or script as an alarm action.  This can be any kind of custom or third-party utility.  

6.  SNMP traps
SpaceGuard can send messages to other computers in the form of an SNMP trap.  These SNMP traps can be received by computers running operating systems other than Windows NT/2000.  For instance, when integrating SpaceGuard with a central, UNIX based management console, SpaceGuard can send messages directly to that application.
