An incremental backup is a backup of every file on a file system which has changed since the last backup. The alternatives to an incremental backup are differential backup and full backup. An incremental backup is the fastest backup and requires the least storage space on the backup media. However, incremental backups also require the longest time and many tapes to restore. Incremental backups should be used only in environments where backup time or backup storage media are extremely constrained. For most environments, a weekly full backup and a daily Read More
