Best Practices for ShadowSnap on Small Business Servers


1. Background

This article discusses best practices for installation and maintenance of ShadowSnap on Small Business Servers.

2. Small Business Servers

Windows Small Business Servers provide many aspects of functionality for SMB clients who may only have the resources for a single server environment.

They can be configured to support DNS, DHCP, Exchange, SQL and other server functions. While this provides for a high level of service from an availability standpoint, it causes excessive drain on the server's resources.

By default, Small Business Servers consume all available memory on a machine, leaving very little resources free. This can cause issues when attempting to back up with either ShadowSnap or ShadowProtect.

3. Preventing Resource Over-Allocation

For Small Business Servers running Exchange and SQL, it may be best to change the allocation of resources of the Exchange and SQL services to limit memory utilization.

As of Exchange 2010 SP1, you must set the msExchESEParamCacheSizeMin parameter or the msExchESEParamCacheSizeMax setting will be ignored. In Exchange 2007 - 2010, you can simply set the msExchESEParamCacheSizeMax parameter.

Steps to manually modify some of these settings can be found here:

This article also discusses being able to do the same with SQL services:

If backups are running slowly or are intermittently failing with resource errors, these steps may assist with limiting memory usage.

We advise caution when performing the steps outlined. Any time modifications are being made to the registry, you should perform a registry backup and reboot the server upon completion of these changes.
