What are backups?
Why are backups needed, what needs to be backed up?
Types of backups
- Very fast and convenient to backup
- Can be Automated with little external input / monitoring
- Cheaper than HDD Backup
- DVDs can be easily and cheaply posted to a secure off-site location
- DVD Backup is not as reliable as HDD backup
Tape Drive Backups
- Vastly cheaper than HDD or DVD Backup
- Data can only be accessed sequentially (because it is a tape) which means very slow restoration rate if needed.
