Online data backup offers greater security
We can describe several aspects of security:-
1) Physical security
2) Electronic security
3) "Procedural" security
I'll take each of these in turn starting with physical security and explain how online data backup can help.
This is where companies perhaps fail the most and are extremely vulnerable. Tape/CD/DVD backups are kept on the shelf just above the desk or taken home and kept in the house. Most companies wouldn't even dream of keeping thousands of pounds in box at home on the shelf yet important files can have a similar value.
In most cases such files are valued higher than the direct monetary value anyway due to the length of time it took to gather the data. For example, if you lost your subscribed email marketing database of 3,000 contacts the monetary value might be X and the time it took to compile the list could have been over several years.
So what would be the ideal solution? An off site location with physical security similar to that provided by a bank vault. The main telecoms and internet providers already utilise such locations given the amount of value placed in their facilities.
Physical security includes 24x7 CCTV, patrolled security, interruptible power supplies, restricted access and fortified building walls. Place your tape/CD/DVD in such a facility and you'll experience decent physical security.
A professional online backup system will already store your files in such a location - a secure data centre. All the physically secure aspects above will be in place.
As well your files will be stored in at least two different data centres providing additional security. This can be time consuming and impractical if using a tape system that took all night to backup!
So physical security is implicit in a good professional online backup solution, even when backing up small numbers of files.
