The backup appliance have become smarter
with time. The increasing pressure of having less storage space and more data
to accommodate, is resulting in innovative and efficient solutions such as CBT.
The changed Block Tracking backup allows the system to take the backup of only
those blocks of data which have undergone a change.
CBT does not Waste Storage Space
It reduces the
amount of data as it does not copy that data which has remained the same. This
offers smart usage of the storage capacity. It does not waste the space
available for data storage on copying the data again and again.
CBT Saves Precious Time
In addition to
consuming the storage space in a smart way, CBT also contributes in terms of
saving time, which is very important part of a backup appliance’s role in the industry. Not making the copies of
unnecessary and unchanged blocks of data saves time which would have made the
process considerably slow.
In this type of
a backup appliance which offers CBT,
the entire data on the VM is not backed up which makes it a smarter way of
backing up the data. This smarter backup
needs an equally smart backup
appliance such as DR 365 by StoneFly which offers this and many other
features to make your experience worthwhile.
When there is
less amount to data to handle, it becomes easier to keep the relationship with
the enterprises positive. The trust factor is not disturbed as you can provide
them with faster and efficient data accessibility and recovery.
What does CBT Require?
Changed Block
Tracking backup require some infrastructure to run. ESX/ESXi hosts are required
for CBT to run and the version of these hosts must be 4.0 or recent to that. In
addition to this, the Virtual Machines must be of virtual hardware version 7 or latest. Veeam backup appliance is used for backup and replication as per your data need.
The CBT actually
informs the vSphere or any other backup tool to copy only the blocks which have
experienced some change, while not copying the ones which are the same. It does
not unnecessarily copies the data to the backup which reduces the amount and
time taken in the backup process.
Offers No or minimum Latency
By using CBT, a
business can have minimum or no latency issues as only the data that needs to
be backed up really is considered and rest of the data on the VM is ignored,
there is no latency that is undesirable. We must keep it in mind that if there
are so many blocks which have undergone changes, then there might be a little
latency, this is why we have not mentioned no latency, just to be honest.
One major
drawback of CBT is that it can miss out on the changes occurred to the data
blocks during the hardware failure or any other kind of incident like power
outage. Azure cloud backup can be used as data backup also.
Conclusion
Changed Block
Tracking (CBT) is a type of data backup that really saves time and frees
storage space. Both of these features are very crucial for modern backup appliances to have in them. A
solution that offers this feature should be preferred as it provides the
enterprise with optimum use of space storage and also that it does not waste
time where it can be saved.
