Unitrends system resource considerations for Windows Instant Recovery - Connect IT Community | Kaseya
<main> <article class="userContent"> <h2 data-id="summary"><strong>SUMMARY</strong></h2> <p>To provide information advising customers how to check to see if their appliance can run instant recoveries.</p> <h2 data-id="issue"><strong>ISSUE</strong></h2> <p>The Unitrends appliance has the ability to run a Windows instant recovery, but the virtual failover client (VFC) residing on a Recovery-Series appliance uses the appliance's resources and impacts system performance. Processors, memory, and storage are assigned to the VFC, so less system resources are available for functions such as backups, archiving, replication, and deduplication. Retention is also impacted, as storage allocated for instant recovery cannot be used for backups.<br> </p> <h2 data-id="resolution"><strong>RESOLUTION</strong></h2> <p>Before creating a VFC on a Recovery-Series appliance, check the system load and utilization to determine whether the appliance has adequate resources to perform other functions while also running the VFC.</p> <h2 data-id="tasks"><strong>TASKS</strong></h2> <p><b>Determine the system load and utilization (HTML5 user interface)</b> </p> <ol><li>On the <b>Reports</b> page, select the <b>Appliance</b> category and select the <b>Load Report</b>. You can choose the appliance and set the date range you want to view. Verify the system load is at an acceptable level.</li> <li>If VFCs are currently residing on the appliance, go to the <b>Recover</b> page, click on the <b>Instant Recovery</b> tab, select a VFC, and then click <b>Edit</b> to see resource utilization snapshots for processor, memory, and storage.</li> </ol><b>Determine the system load and utilization (legacy user interface)</b> <ol><li>In the Navigation pane, select the backup system or replication target where the VFC will run.</li> <li>Click on <b>Settings > System Monitoring > Load</b> and verify that the system load is at an acceptable level.</li> <li>If VFCs are currently residing on the appliance, select <b>Settings > Instant Recovery > Windows</b> to see resource utilization snapshots for processor, memory, and storage.</li> </ol><h2 data-id="notes"><strong>NOTES</strong></h2> <p></p> <p>If the system is consistently in the Alarm Area for prolonged periods of time or if backups are not completed in the desired backup window, reconsider the number of VFCs on the appliance.</p> </article> </main>
