USER EDUCATION: Training your staff in various aspects of computer operations can minimize data losses, particularly losses caused through human errors, which are a major cause of data loss. Staff can be trained to take the necessary precautions, such as backing up, antivirus checking, working through firewalls, but there should always be someone in charge the security of data.
BACKUP: The impact of data loss can be minimized through well-implemented data backup procedures. The qualification “well-implemented” is important. Often, data backup is done in a routine manner without checking whether a full data recovery is possible in case original data is lost.
Data backup might not be up to date. Data in backup media can prove irrecoverable owing to improper backing up or media corruption. It is important to make regular reviews and tests of both back up procedures and backed up data to ensure that the data is indeed recoverable if it becomes necessary.
Storing backed up data in a location away from the primary data location can help in such cases as a fire / flood or other natural disaster.
ANTI VIRUS & FIREWALL SOFTWARE: Anti virus software, if kept up to date, can help guard against virus attacks. Firewalls can stop most hackers from hacking into your systems.
REDUNDANT MEDIA AND WRITE OPERATIONS: Data is written to more than one media device or location so that if one of them fails, the other can be used to repair the damage.
