What types of backup schemes are available?
Also question is, how many types of backup are there?
Secondly, what is the slowest type of backup restore? Incremental vs Differential vs Full Backup
|Incremental Backup||Full Backup|
|Advantages||Faster backups Less storage space used. No duplicate files||Fastest restore Only needs the last full backup set to restore|
Hereof, which backup type only backs up files that have changed since the last run?
Incremental backup is a backup of all changes made since the last backup. With incremental backups, one full backup is done first and subsequent backup runs are just the changes made since the last backup. The result is a much faster backup then a full backup for each backup run.
What is a full backup?
A Full Backup is a complete backup of all files on the designated hard drive. An Incremental Backup is a backup of all changed files since the last Full or Incremental backup. For example: Friday - Full Backup.
