Replication Monitoring
It It
The aim of replication is to ensure that data is ―moved‖ offsite as quickly as possible after a backup job
completes. The ―maximum time to offsite‖ varies depending on business requirements. The D2D Backup System
provides tools to help monitor replication performance and alert system administrators if requirements are not
being met.
Configurable Synchronisation Progress Logging and Out of Sync Notification
These configurable logging settings allow the system administrator to take snapshots of replication progress as
log events and at fixed hourly points in order to get a historical view of progress that can be compared to
previous days and weeks to check for changes in replication completion time.
Out of Sync notifications can be configured so that an alert is sent if the required maximum time to offsite is
exceeded.
If these logs and alerts indicate a problem, best practices may be applied in order to get replication times back
within required ranges.
Replication Activity Monitor
The
Status - Activity
page has a graph to show Replication Data throughput (inbound and outbound) over the
last five minutes. The throughput is the sum of all replication jobs and is averaged over several minutes. It
provides some basic information about replication performance but should be used mainly to indicate the general
performance of replication jobs at the current time.
