Q & A
What is the Recovery Time Objective (RTO)?
-The Recovery Time Objective (RTO) is a time frame that defines how long it will take for an organization to be considered up and running after an outage. It includes the time required to get critical systems operational, such as the database and web servers.
Can you provide an example of how RTO is determined?
-An example of RTO could be the time it takes to get both the database server and the web server operational. If an organization considers itself up and running only when both systems are functioning, then the time to achieve this state is the RTO.
What is the Recovery Point Objective (RPO)?
-The Recovery Point Objective (RPO) is a point in time up to which data must be restored to consider the system operational after an outage. It's the minimum amount of data necessary for the system to function effectively, such as having at least the last 12 months of data available for customer reference.
How does RPO differ from RTO?
-While RTO focuses on the time frame to get systems operational, RPO is concerned with the specific data restoration point required to consider the system operational. RTO is about system availability, whereas RPO is about data availability.
What is the significance of understanding the time to fix a problem in outage planning?
-Understanding the time to fix a problem is crucial for outage planning as it helps in estimating the average amount of time required to resolve an issue. This includes diagnosing the problem, obtaining replacement equipment, installing it, and configuring it, which can influence the overall downtime.
How can the mean time to repair (MTTR) be reduced?
-The mean time to repair (MTTR) can be reduced by having a contract with a third party for quick replacement of equipment or by purchasing additional equipment to have on site. This allows for quicker resolution of outages by minimizing the time spent waiting for or configuring new equipment.
What is the Mean Time Between Failures (MTBF) and how is it used?
-Mean Time Between Failures (MTBF) is the estimated time that a system will run before another outage occurs. It is commonly used for planning purposes to assess the risk associated with using a particular piece of equipment and to predict potential downtime.
Who typically provides the MTBF value for a piece of equipment?
-The MTBF value is typically provided by the manufacturer as a prediction based on the type of equipment or it may be based on the historical performance data of that equipment over time.
How can one calculate the MTBF for a system?
-The MTBF can be roughly calculated by dividing the total uptime of the equipment by the total number of breakdowns. This gives an estimate of how often the system is expected to fail.
What is the relationship between MTBF and the risk management of downtime?
-MTBF helps in managing the risk of downtime by providing an estimate of how frequently a system might fail. It allows organizations to predict potential issues and plan for maintenance or upgrades accordingly.
How can additional resources or investments impact the RTO and MTTR?
-Additional resources or investments, such as having a contract for quick equipment replacement or purchasing extra equipment, can significantly impact the RTO and MTTR by reducing the time required to get systems back online and resolve issues.

Transcripts
When recovering from an outage, one
of the statistics that managers want most of all
is how long is it going to be before we get back up
and running.
The technical term for this is the recovery time objective,
or RTO.
The RTO is a time frame that defines
how long it is before we can get up and running.
For example, your organization may not consider you up
and running until both the database server and the web
server are operational.
The time frame it takes to get both of those systems running
would be the recovery time objective.
Another useful measurement would be the recovery point
objective, or RPO.
Recovery point objective is a point in time
where we can say that we are now up and running.
For example, we may only consider ourselves operational
if we have at least the last 12 months of data
available for our customers to reference.
And if we have to reload data from our backups,
we know that we have to get at least 12 months of data
in the database before we can say
that we are now up and running.
That 12 months of data is referred to as our recovery
point objective.
When planning for outages, we need
to understand how long it will take to fix
a problem that has occurred.
This describes the average amount of time
it takes to resolve a problem that may have occurred.
And that includes both time to diagnose, time
to get replacement equipment, time to install the replacement
equipment, and then get that equipment configured.
This is often a value that we can
change based on what resources we might have available.
For example, you might have a contract with a third party
where they provide a replacement equipment within two hours
if there's an outage.
Or you might purchase additional equipment to have on site,
so if an outage occurs, you can simply pull that new equipment
out of inventory.
This means that you may be able to spend a little bit
more money now to decrease the total mean time to repair.
If you're purchasing new equipment for your network,
you may notice that that equipment also
includes a value for MTBF, or mean time between failures.
This is the estimated time that the system will
run before there is another outage,
and it's commonly used for planning purposes
to know how risky it might be to use that particular piece
of equipment.
This might be provided by the manufacturer
as a prediction based on the type of equipment
that you're using or it may be based
on the historical performance of that equipment over time.
You can perform a rough calculation
of mean time between failures by taking
the total uptime for that equipment
and dividing it by the total number of breakdowns.
This allows you to manage the risk of that downtime
and predict when there may be issues
associated with that particular piece of equipment.
