		<description><![CDATA[Using snapshots to protect Active Directory (AD) without careful planning will most definitely end up in a complete disaster. AD is a loosely consistent distributed multi-master database and it must not be treated as a static system.  Without carefully addressing how AD works with Time Stamps, Version Stamps, Update Sequence Numbers (USNs), Globally Unique Identification numbers (GUIDs), [...]]]></description>

		<description><![CDATA[The ability to perform file system, database and volume snapshots grants us many data protection benefits. However there are some serious problems that can occur if we do not carefully architect snapshot based storage infrastructures. This blog entry will discuss some of the issues with data noise induction and data integrity when using point in time [...]]]></description>

What was traditionally a closed and proprietary storage capability is now available to our open source communities. With OpenSolaris and COMSTAR the ability to freely provision virtual storage services over very mature high end protocols on standard commodity server hardware is now a reality. High performance transports [...]]]></description>

As a follow on to my blog entry Provisioning Disaster Recovery with ZFS, iSCSI and VMware I created this snapshot rollup script to help maintain the growing snapshots and minimize disk consumption. The script is an add-on to the zfsadm account cron jobs and runs under the security privileges of the zfsadm user detailed in that [...]]]></description>

		<description><![CDATA[OpenSolaris, ZFS, iSCSI and VMware are a great combination for provisioning Disaster Recovery (DR) systems at exceptionally low cost. There are some fundamentally well suited features of ZFS and VMFS volumes that provide a relatively simply and very efficient recovery process for VMware hosted non-zero RPO crash consistent recovery based environments. In this weblog I will demonstrate [...]]]></description>
