The Daily backup type is sort of an Differential off-shoot. In this backup type, only files that were changed (have the archive bit on), during the current day are backed up, and the Archive bit is left unchanged. This backup type is generally not used as part of a recovery program, because in order to do a full system restore, you would have to have a Normal backup, and then a Daily backup from each and every day since the Normal backup.

A full backup

They have the equipment and financing to perform a full backup daily. This results in a quicker restoration in case of failure although it takes more media to perform this task.
A full backup contains all files that you have chosen to have backed up. A differential backup will only contain the files that have changed since the last full backup. One commonly used schedule is to do a weekly full backup, and daily differential backups.
Five type of backup they are :1. Normal backup - It copy all the files marked in to be backup2. Incremental backup - only those files that have been created or changed since last incremental or normal backup.3. Decremental backup - The only copies files that have been created or changed since the last normal or incremental backup4.copy backup - It copy all the files u have selected5. Daily backup - It copy all the files u have selected that have been modified on the day
monthly, weekly, and daily backup jobs
Monthly-Weekly-Daily... Files changed since Wednesday (a day before)
there are three main types pf NT backup in server / windows You can make it A normal because it take backup of all files & folders.
Totally depends on the backup methodology and the rotation scheme. I have a couple of clients that backup everything everyday and keep the tapes for two weeks. They have 14 copies. Other's backup everything (or changed data in some cases) everyday, and keep the daily copies for two weeks, but keep the weekly tapes for months. There could be 30-40 copies in those cases.
Incremental Backup. There 3 data backup types, full backup, incremental backup and differential backup and the only backup type that clears the archive bit is incremental.
An incremental and differential backup does that. An incremental backs up files that were changed since the last backup, whether it was full or another incremental. A differential backs up all files that have changed since the last full backup. Incremental backups backup faster. Differential backups restore faster.
A backup generator keeps you out of trouble if the power goes off in your neighborhood. You can temporarily use a generator to run your appliances so that you have light, a refrigerator and other important functions needed on a daily basis. Make sure that you buy a backup generator that is the right size for your needs; it might be necessary to estimate the amount of power that you need before you go shopping.
