journal-based technology to keep a log
of all the changes occurring in a specified
timeframe, offering any point-in-time
recovery in increments of seconds for the
entire length of the journal. Conversely,
incremental replication and snapshots put
the business at risk of data loss, corruption
and availability. What companies can utilise
now is continuous journal-based recovery
that provides granular recovery to within
seconds of data that can go back seconds
or multiple years as needed. The option
to recover to many more granular points
in time minimises data loss to seconds,
dramatically reducing the impact of outages
and disruptions to the business and its staff.
• No performance impact: With CDP, the
journal is only used until you commit to
the point in time selected, without the
performance impact of many snapshots.
Storing multiple snapshots on replica
VMs incurs a significant performance
penalty when attempting to power on
replica VMs.
• Journal-based any point-in-time
recovery: Journal-based recovery keeps
a constant log of all the changes users
make to applications and data. Because
the changes are continuously written to
the datastore, CDP delivers any point-in-
time recoverability to within a specified
time frame.
• Enterprise scalability: The journal
can be placed on any datastore with
maximum size limits and warnings –
preventing the datastore from filling
which would otherwise break replication.
Using snapshots on replicated VMs gives
no way of controlling the total space used
for snapshots, making them not scalable
in terms of SLAs and efficiency.
• Storage savings: CDP uses no extra
space in the source storage as no
snapshots are created. Only minimal
additional storage on the target site is
used which frees up significant amounts
of space and results in dramatic
savings. Snapshot technologies require
significant overhead on the storage
arrays, often requiring 20–30% at both
the source and target.
• Ransomware recovery down to the
second: CDP delivers a continuous
stream of recovery checkpoints available
to use for recovery. In the event of
ransomware or other malicious attacks,
data can be recovered to just seconds
before the corruption took place,
minimising impact to the business and
the brand.
By moving from periodic, snapshot-
based processes to a continuous process,
enterprises can better meet today’s 24/7
demands of no data loss or downtime.
Although, while it’s obviously important to
think about how a tech-related disruption is
going to impact a business financially, it is
also important to think about how it’s going
to impact the humans that have to deal with
and recover from the disruption.
Making sure all of your employees feel
well-trained and confident on all technology
platforms available to them, and making your
IT department feel equipped and ready for
any threat thrown its way – with the right
tools to do just that – is going to save a lot of
labour hours and keep employee morale high.
These are all necessary for long-term
employee retention, which goes hand-
in-hand with recruiting top talent in your
industry. Have you prepared for all angles of
a disruption? n

• Real-time block-level replication:
CDP utilises change-block tracking to
constantly replicate data as it is written
to storage. Because CDP is always-on,
it offers considerably lower RPOs than
snapshot-based solutions.
