What are the three types of Backup?
Full, Incremental, Differential backups
Backs up the entire set of data to the chosen place.
Takes the most disk place, time and PC resources on backing up.
The easiest and fastest to restore.
Processes only files that appeared or changed since the previous backup. Index file is updated
: use the least time and space as only those files changed since the last backup are copied; lets you backup multiple versions of the same file.
: Long restore, which consist of the full backup and all subsequent Incremental backups; hard to located a particular file int the backup set
Backup of those files which have change since the last full backup. Index file is not updated
: Takes up less time and space than a full backup; provides for more efficient restoration than incremental backups.
: Redundant information stored, because each backup stores much of the same information plus the latest information added or created since the last
full backup. Faster restore than Incremental. Subsequent differential backups take longer and longer as more files are changed.
