Backup vs. Disaster Recovery
Backup is essential for all businesses. Backup ensures that you can restore your data in an event of data loss and continue with business as usual. However, in an event where you have lost the very thing you need to restore your data to, you will need a full system recovery. Here we’ll explain the difference between the two.
With our backup software, Clunk Click Online Pro, we will take a copy of your files and store it in our datacentre. The backups will be scheduled and will happen automatically meaning that there’s no human intervention required. You can choose what data you want to backup from your system and how often.
Clunk Click Online Pro scans for three types of data: data that is new, data that existed during the last back up but has changed, and data that existed during the last backup and hasn’t changed. This minimises bandwidth meaning you can backup your data without interfering with your working day as no duplicated data is being sent.
Clunk Click Online Pro can backup all data types including flat files and transactional databases. It also has version control. This means that we keep multiple backups so if a virus has gone undetected you can restore your data from a time prior to infection, not just the most recent one.
In the event of data loss, if you need access to a file you can use:
- InstantData which will allow you to instantly view your data via a web browser.
- Single file restoration where you can restore just one file.
- Multiple file restoration where you can restore some or all of your backed up data onto your server.
Disaster Recovery (DR)
In a scenario where your computer or server is inaccessible, you will need somewhere to restore your data to. This might be a spare server, your previous server if it is still intact, or a Virtual Machine (VM) in a datacentre. If you use a new server, either physical or virtual, you will have to spend time configuring and setting up your new server. This is where disaster recovery comes in.
Our Disaster Recovery solution means that we’re able to complete a Full System Backup and therefore a Full System Recovery. When it is initiated, we will take a copy of your physical server’s settings and configurations and install them onto a Virtual Machine (VM) in our datacentre. This means that in an event of a disaster or if your office server is physically damaged, you have a pre-configured server ready to restore your data to.
There are two different types available: Warm State Disaster Recovery and Hot State Disaster Recovery.
Warm State Disaster Recovery means that in a data loss scenario, we will recover your data from your last Backup before restoring it onto the pre-configured VM.
Hot State Disaster Recovery however, means that after each backup is completed, a copy will be recovered onto your VM, so when it comes to the restoration you’ve essentially shortened the process and therefore you can get your business up and running in no time at all.
To help differentiate between Backup, Warm State and Hot State Disaster Recovery here is a scenario that we’ve recently encountered.
One of our clients’ servers, made by Hewlett Packard, had a hard drive failure meaning that their server could no longer function properly. After contacting HP they found out that it would take 5 weeks for the new disk to arrive. Whilst they backed up their data with Clunk Click Online Pro they no longer had a server to restore the data to.
One option would be to spin up a VM to restore their data to, but that would need setting up and configuring in exactly the same way as the failed server which would take valuable business time.
Fortunately, the client had initiated Hot State Disaster Recovery. This meant that we had previously taken a copy of their physical server’s settings, installed it onto a VM in the datacentre and regularly backed up their data to it, meaning they could access the data on their VM via a Virtual Private Network.
In other words, their failed onsite server was replaced by the VM in the datacentre.
This significantly reduced downtime and meant that a situation which would’ve had huge financial implications on the business was minimalised, dealt with, and became nothing more than a nuisance.
Please Note: Warm State Disaster Recovery would also have worked in this situation, but due to the volume of transactions, downtime would be costly for this particular client meaning that Hot State Disaster Recovery was the best option.
Our pricing works as follows.
For Clunk Click Backup Pro you pay for your storage amount. For Clunk Click Warm State DR you will pay for your back up storage amount and a small monthly retainer fee for the target VM.
In the instance that you invoke Disaster Recovery, you would pay the full cost for the use of the VM (based on CPU/RAM/Disk).
If you plan to move your data back down to a physical server, you will only pay the full cost of the VM when it’s in use (using the above example this would’ve been 5 weeks whilst they waited for their replacement server disk).
For Clunk Click Hot State DR, you would pay for your backup storage and for the cost associated with the use of the VM (based on CPU/RAM/Disk).
You then have the option to move your data back down to a physical server, or keep your VM and we can set up a new one for Full System Recovery.
We recommend that you have a chat to us about which option is best for you and your business.
