Autonomous Self Healing is a process which runs in real time on
Databarrack's backend storage systems and continuously checks and
validates incoming data.
B.L.M. allows data which is no longer current to be
automatically archived to a lower cost enviroment within
Databarrack's data centre for long term storage. B.L.M. allows data
to be retrieved immiediately online whilst at the same time
ensuring the amount of data stored is as cost effective as
A 'Bare-Metal' backup/restore is the most effective way of
backing up data to ensure the quickest possible restore time.
'Bare-Metal' as it implies takes the entire contents of a computer
or server including all of it's settings, operating system and
applications as well as data.
C.D.P. Allows for file and M.L.R. email backups to happen in
near real time. Not only does this allow organisations to ensure
that they are able to retrieve data that has been created during
the day, but also means that scheduled nightly backups have as
short a backup window as possible. Running C.D.P. during the day
does not impact on an organisation's bandwidth usage, CDP allows
other internet facing applications prioity.
As with de-duplication, common file elimination removes files
that are duplicated across your data enviroment. Common File
Elimination differs from de-duplication in so far as it is a common
file used by all enviroments. It is useful, for example, when you
are using 'bare-metal' backup on all servers but do not want to
store multiple versions of an operating system. Common file
elimination will remove all of the common .dll and other files that
make up most operating systems and applications common in a wide
number of organisations.
Online Backup Software has the ability to backup data to
pre-determined retention policies. Simply put, this means that data
can be stored for varying periods of time as with a traditional
tape backup (Grandfather, Father, Son). This allows for Online
Backup Software to be a direct replacement for tape, retaining data
in the same manner as a tape rotation would. Retention rules can be
used alone or in conjunction with B.L.M. (Backup Lifecycle
Management) or archiving to allow for organisations to comply with
best practices and data retention regulations.
As with Autonomous Self Healing, Data Validation is a tool
within the Online Backup Software that checks for any corruption in
the data sent for storage. Data Validation is a process that can be
scheduled by the end user in the same way that a backup can.
Data de-duplication describes the method by which the Online
Backup Software removes data that has been duplicated throughout
your IT infrastructure. De-duplication works on digital file
signatures and ensures that data is not unnecessarily stored on
Databarracks storage servers. De-duplication works across multiple
sites and on all data. For example if you have a large number of
users in your organisation who all have the same word document in
their local profiles, de-duplication would remove the copies and
reduce the amount of storage used, leaving pointers to the data to
replace the duplications.
A Faraday cage or Faraday shield is an enclosure formed by
conducting material, or by a mesh of this material. Such an
enclosure blocks out external static electrical fields. Faraday
cages are named after physicist Michael Faraday, who built one in
1836. An external static electrical field will cause the electrical
charges within the conducting material to redistribute themselves
so as to cancel the field's effects in the cage's interior. This
effect is used, for example, to protect electronic equipment from
lightning strikes and other electrostatic discharges. All
Databarrack's storage systems are housed within Faraday Cages.
High Energy Radio Frequency (HERF) or High Power Radio Frequency
(HPRF) weapons are weapons that use high intensity radio waves to
disrupt electronics. They are a type of directed-energy weapon.
They operate similarly to electromagnetic pulse (EMP) devices, by
inducing destructive voltage within electronic wiring. They are
often directional and can be focused on a specific target using a
parabolic reflector. Faraday cages may be used to provide
protection from some HERF and EMP effects. Databarracks Data Centre
protects against H.E.R.F. by housing all storage systems within
Hierarchical storage management or H.S.M. is the term used to
describe the automatic moving of data from a higher cost storage
medium to a lower cost medium. Online Backup Software software uses
H.S.M. in both the migration of backup data from Databarracks'
S.A.N. environment to a lower cost N.A.S. environment and
ultimately after that to a choice of long term storage media.
A 'Hot Backup' is a backup of a database or other application
whilst they are still operational. Online Backup Software is able
to perform 'hot backups' on a wide variety of databases and
applications to ensure that there is no down time for an
organisation while the backups are running.
I.L.M. is a term used to describe the entire cycle that Online
Backup Software uses to protect and manage data backup. Online
Backup Software not only backs up data, but also manages it through
it's life cycle. An example of this is as follows: 1.
De-duplication of data 2. Backup of data 3. Retention of data 4.
Archiving of data 5. H.S.M. (Hierarchical storage management)
Local Storage is an additional copy of data that is stored
on-site. By default Databarracks will keep a local copy of data
on-site which ensures that data can be restored at network speed in
the event of a data loss or server loss.
M.L.R. or Message Level Restore is the process which allows
Databarracks to backup email from M.S. Exchange, Lotus Notes,
Groupwise and Outlook in a very granular manner. Most email
recovery is single message and M.L.R. allows users to restore a
single message, single folder or users mailbox back into the live
email enviroment without interruption to the email server. M.L.R.
can also be used as an effective way of managing an email archive
within an enterprise email enviroment and keeping the individual
mailbox quotas low.
RPO stands for Recovery Point Objective and describes the point
in time to which a company needs data recovered. For example, if a
company run overnight backups, the recovery point objective will
often be the end of the previous day activity.You can run backups
more often to rule a tighter RPO.
RTO stands for Recovery Time Objective and it is the acceptable
timeframe respected by SLA and to which certain business data needs
to be restored after a data loss, to avoid critical consequences to
business disruption. Different business applications can have
different time objectives that should be respected during the data
According to definitions from the Uptime Institute and TIA-942
(Telecommunications Infrastructure Standard for Data Centres), a
Tier 1 data centre is not required to have redundant power and
cooling infrastructures. It needs only a lock for security and can
tolerate up to 28.8 hours of downtime per year. In contrast, a Tier
4 data centre must have redundant systems for power and cooling,
with multiple distribution paths that are active and fault
tolerant. Furthermore, access should be controlled with biometric
readers and single-person entryways, gaseous fire suppression is
required, the cabling infrastructure should have a redundant
backbone, and the facility can permit no more than 0.4 hours of
downtime per year.
