A number of factors can influence a businesses aversion to risk including the risk of a disaster affecting their business data. A disaster would consist of a situation where some or all business data is lost and unrecoverable. Disaster Recovery Planning seeks to eliminate data loss and reduce operational losses to the business from unanticipated system down time.
The most common factors influencing a businesses disaster planning include:
- Previous disastrous loss of data
- Compliance requirements in service provider or supplier contracts
- Insurance requirements stipulated by 3rd parties
- Procedural requirements as part of company policy
Disaster Recovery Planning should incorporate procedures for multiple scenarios that may have different degrees of impact on the business. These might include:
- Accidental data loss or deletion
- Data storage equipment failure
- Significant disaster such as majour fire or flooding
In each instance the severity of the impact to the business is different, however the recovery procedures for each provide some overlap and redundancy. This overlap provides greater data security for the business and provides multiple data recovery points. This means that lost data can be recovered from several different backup sources. This provides flexibility in the recovery process but the added benefit of being able to retrieve historical versions of data if required.
A 3 layer approach to data backup and retention is generally advised. This provides the most comprehensive mix of data recovery options.
In house full or incremental backup procedures provide the first line of defense against data loss. A fast and convenient method for retrieving data that may be accidentally lost such and deleted documents. Storage capacity provides for multiple days of back ups which be stored to a single volume. Multiple drives swapped regularly ensures that daily backups covering several weeks can be stored.
While considered a second layer of data protection, preparation of solutions for this type of disaster are planned at the implementation stage of any new application or file server. This type of solution is incorporated into the configuration of a servers hard drives. Selecting the right solution for the businesses needs and budget will impact the downtime experienced due to the failure of a hard disk drive. With the right solution a business will experience little or no down time in such situations.
Solutions for this level of data lost can be utilised in other situations and not just where complete system loss is considered a possible scenario. For total data loss situations the only viable disaster recovery path relies on the off site storage of the businesses corporate data and where necessary system images for bare metal recovery situations.
Bare metal recovery scenarios include the need to deploy a completely new server solution to replace one that has failed, been damaged or even reached obsolescence.
While not an exhaustive description of disaster recovery options and solutions, these are the most likely options to be deployed by businesses with Disaster Recovery plans in place.
