- Methods used to prevent accidental misuse of data
- Standard backups to floppy disc/portable HDD
- selected files is copied to a portable storage medium
- Can be scheduled using automatic backup software scheduling
- network admin may have to plug in and store the portable HDD- often kept off site
- RAID systems - mirror disks (Redundant Array of Inexpensive Disc)
- All data is simultaneously written to >1 HDD. If one HDD fails the system will automatically switch to using the 2nd (or 3rd or 4th...). Useful when there can be no downtime
- Grandfather, father, son systems
- 3 generations off files are kept.
- Used in transaction processing systems so that data can be recovered from before the production of bills
- Backing up programme files
- Used so that specialised software will be backing up
- Actual programme files themselves (that enable production of data) can be kept in case they become corupt
