• The tape is worn out and has not been checked, making data unreadable.
• A backup tape is stolen at the same time as a PC or server.
• The backup tape is stored in a glove compartment, 18 inches from the car’s starter motor. The magnetic impulses erase your records.
• Fire, flood or vandals destroy the backup along with your system.
• Someone makes a mistake while doing a backup and crashes both the system and your duplicate copy.
• Old tapes or disks haven’t been replaced – data is not stored.
• The restore feature of your backup system has never been tested, and when it comes to the crunch, it doesn’t work.
• The backup tapes or disks are stored close to a PC monitor, television or power supply. Electromagnetic radiation destroys your data.
• The person responsible for implementing backups claims to have been too busy to perform a backup recently.
• The magnetic heads on the backup hardware have not been cleaned for a year or so, so data hasn’t been recorded for over six months.
