What is offsite backup?
Today, most organisations are clear about the need to protect their most
important asset - their data. Human error, a PC crash, a virus, malicious
actions, flood, fire, theft or loss of a laptop - can all too easily put this
data and therefore the business at risk.
An offsite backup is a secure, simple and affordable alternative to a traditional tape backup solution.
Tape backup solutions can sometimes be effective, but they need upfront investment, ongoing maintenance and internal staff to maintain and operate them. The word 'hassle' best describes tape backups - especially during a crisis when key data is to be recovered without delay.
Offsite backup is a modern yet proven solution to this niggling and critical process.
topWhat are the benefits of offsite backup?
Offsite backup is cheaper, faster and better than tape backup. Perhaps a
bold statement, but here are some of the arguments:
Cheaper -
Faster -
Better -
How does offsite backup work?
A small software agent is installed on the computer. This
software helps select the data to be backed up, manages the
connection to the internet and the encryption / compression of the data - prior
to transferring it to the data centres. A simple view is provided to see, select
and restore backed up documents.
Various backup modes - scheduled or manual
-
Backups can be performed at any time with a single click or be set for hassle-free daily backup.
Secure
-
Security is provided through secure-sockets connections to the data centres,
128-bit encryption and account passwords.
Effective and fast data transfer
-
Compression and delta-blocking ensure regular backups are very efficient and non-intrusive.
Web browser option to restore data
-
Data can be accessed via the software agent at any time or via a
web browser when travelling away from the office.
CD restore and archiving options
-
CD's can be ordered containing a copy of the software agent, as well as all backed
up data in case of complete PC / disk loss - or for archiving.
File sharing
-
Users can grant sharing
permissions to other users. This is a secure process that allows co-workers
to share key documents, service providers to share documents with clients and
tele-commuters to access both office and home data.
Who uses offsite backup?
Offsite Backup is used by tens of thousands of organisations in the UK including
law firms, accounting firms,
consulting organisations, financial intermediaries, manufacturers, education and
research establishments, retail outlets, distributors, not-for-profit and service
organisations.
Organisations of all sizes with an internet connection can benefit: independent workers, SOHO environments, branch offices, large enterprises, local and national government.
topWhat are the limitations of offsite backup?
Offsite Backup needs an internet connection to work. This can be traditional dial-up or ISDN for smaller data volumes,
or ideally
a broadband connection such as ADSL, Cable, DSL and Leased
Line. These have the advantage of faster transmission rates, no usage
call charges and the ability to handle large volumes of data.
Dial-up / ISDN connections can backup around 500MB of data. ADSL / Cable works well for around 10GB of data. DSL and Leased Lines can handle significantly more capacity across multiple computers, depending upon the bandwidth in place.
The initial backup process can take some time, because a full copy of the data must be encrypted, compressed and copied to the data centres. Further daily backups are significantly faster because file changes only are transmitted. These changes are typically at a 'block' level within a file i.e. if a change is made to a previously backed up document, only the change to that document is sent, not the whole document.
Some pseudo-limitations of offsite backup relate to security and price - although these are not significant when fully understood:
topIs offsite backup secure?
Offsite backup is secure. Only secure socket connections are made to the offsite data
centres and data is encrypted to 128-bit level (military grade) before
transmission. Data never travels un-encrypted, including during a restore
process.
A password, an account number and an encryption key all ensure that only the authorised user has access to the data.
The data centres themselves are tier-1 facilities, incorporating fire suppression, security cameras, ID access controls, backup generators, multiple ISPs and high-end firewalls. Mirroring and clustering concepts are used to ensure the data is always available for restore.
These factors together ensure that the service is considerably more secure than the client's own office environment.
topHow much does offsite backup cost?
Offsite backup is charged for on a per computer per month basis, although
companies with multiple computers pay one fixed fee for all their
machines.
There is no setup fee and no software license fee, nor are there additional charges for data transfer and recovery.
Prices start at £10 per month for a PC with 500MB of data, £20 per month for 4GB of data and £35 per month for 10GB of data with additional System File protection. An organisation with multiple PCs can combine these prices to cover all their machines. PCs can backup up to 30GB per machine.
File servers requiring larger volumes (up to 100GB per server) cost more and prices are available on request.
When comparing prices with a traditional tape system, is it necessary to consider the administration costs for a tape backup system. Assuming a conservative 20 minutes per day, this adds up to ten working days per year for an administrator - over £1500 / year in business costs. This is in addition to the costs to purchase and maintain software, hardware and tapes, which can themselves become redundant in time.
Offsite backup is cheaper, faster and better than a traditional tape solution - so why not try it risk-free for 15 days?
