Never underestimate the importance of your business data.
As IT systems have become increasingly critical to the smooth operation of a company, and arguably the economy as a whole, the importance of ensuring the continued operation of those systems, and their rapid recovery, has increased. For example, of companies that had a major loss of business data, 43% never reopen and 29% close within two years. As a result, preparation for continuation or recovery of systems needs to be taken very seriously. This involves a significant investment of time and money with the aim of ensuring minimal losses in the event of a disruptive event.
Some of the most common strategies for data protection are:
- backups made to tape and sent off-site at regular intervals,
- backups made to disk on-site and automatically copied to off-site disk, or made directly to off-site disk,
- replication of data to an off-site location, which overcomes the need to restore the data (only the systems then need to be restored or synchronized), often making use of storage area network technology, and
- the use of high availability systems which keep both the data and system replicated off-site, enabling continuous access to systems and data, even after a disaster.
