An incremental backup has the least amount of files. It contains only those few files that have changed since the last backup.
In contrast, a complete backup does all the files in a filesystem. This is commonly done when backing up to a new set of media for the first time. Consecutive incremental backups can be merged, into the previous incremental backup, or the previous complete backup.
It is considered to be good practice to include several levels of backups. For example, incrementals for the last two days, followed by a complete backup for three days ago, a week ago, and each month before that.

Which backup methodology requires the least amount of time to perform and the most amount of time to restore the system?
Think about what you are asking. If you backup 100 files then you have to reload 100 files, unless you use some faster hardware to do one or the other they will take the same amount of time...there is no answer. But there are different backups depending on how much you want to backup..you can backup your favorites, emails, and documents all at once with backup on the accessories>system tools. Or you can back up your whole hard drive under the same place.
Which backup method is quickest and requires the least amount of backup storage space?
Incremental
Which type of backup copies all files that have changed since the last full backup regardless if they have been backed up since then?
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.
What is the less cost and most powerfull in computer backup?
Back up your files to a CD or DVD at least once a week
What is the technology that uses the least amount of bandwidth to upload files?
Satellite
Why would you perform a differential backup instead of an incremental backup?
An Incremental backup backs up only the selected files that have their archive bit set to ON, setting them back to OFF. This results in a backup of all files that are new or changed since the last backup, whether it was a full or an incremental. The advantage of an Incremental is that it takes the least amount of time and media of all the backup methods.A Differential backup backs up only the selected files that have their archive bit set to ON but does not set the archive bit back to OFF. A Differential backup will back up all selected files that are new and changed since the last full backup. The advantage of a Differential comes at restore time; you'll need only the last full backup and the last differential to get a complete restore. In the case of restoring with Incremental backups, all the Incremental backups since the last full backup plus the last full backup would be necessary.
What is the least amount of power supplies does a fire alarm system need?
The least amount would be a small battery. Some systems are required to have connection power mains with a BACKUP battery.
What data is not contained in course backups in BigGyan Cloud elearning?
By selecting all the options when setting up the backup you can include almost all the data in the course. However you should be aware of the fact that some things are not backed up: * Quiz questions are only backed up if at least one question from their category has been added to a quiz. * Scales are only backed up if they are used by at least one activity.
The Value of Backup Software?
Lost data can be a headache for many businesses and individuals. It's important to have a solid backup plan when working with critical data. The following guide provides several simple tips for using backup software.There are a variety of backup software solutions available on the market. Different backup software will provide varying levels of security.On-site Remote BackupAn on-site remote backup solution will copy all important data and files to a server stored on location. All important files are mirrored on another computer. This can be a great way to backup large files. However, on-site backup doesn't protect individuals from data loss due to theft, fire, or flooding. On-site backup should be used as a primary form of backup. It's also important to have a secondary backup solution for critical files.Cloud Backup SoftwareA cloud backup software solution will mirror all data on a remote server. This has several advantages and disadvantages. Data mirrored on a remote server will be protected from fire, flood, and theft. In addition, remote backup allows for easy restoration of data from a central server.Cloud backup software does have some disadvantages. It can be impractical to transfer large files over an internet connection. While it's possible to mirror documents, music, photos, and small files to a remote cloud server, it may not be possible to mirror a large video file or archive to a remote server. In addition, professional media workers may make daily changes to large video files. A remote cloud server will not be able to sync large files quickly or efficiently.Manual Physical BackupA manual file backup is one of the safest and least convenient ways to backup files. A manual backup requires a copy of all files to be made to a DVD, CD, tape drive, or USB drive. This backup can be placed in a safe, a security deposit box, or another secured location.All companies should make a physical backup of their data at least once a month. It's extremely unlikely that it will be used, but it provides a valuable safety net in the event of fire, flood, theft, and other natural disasters.
Backup is the fastest type of backup?
DATA BACKUPBackup is the act of copying files to a second medium (a diskette, zip drive or tape) as a precaution in case the first medium fails. You can back up files using operating system commands, or you can buy a special-purpose backup utility. Backup programs often compress the data so that backups require fewer diskettes than the original data.Even the most reliable computer is apt to break down eventually. Many professionals recommend that you make two, or even three, backups of all your files. To be especially safe, you should keep one backup in a different location from the others.Full Backup:Is the starting point for all other backups and contains all the data in the folders and files that are selected to be backed up. Because the full backup stores all files and folders, frequent full backups result in faster and simpler restore operations. Remember that when you choose other backup types, restore jobs may take longer.Full backups are often restricted to a weekly or monthly schedule, although the increasing speed and capacity of backup media is making overnight full backups a more realistic proposition.Advantages:1. Restore is the fastestDisadvantages:1. Backing up is the slowest2. The storage space requirements are the highest (compared to incremental backup or differential backup)Hardware requirement: Magnetic tape, Hard disk, Optical storage, Floppy disk, Solid state storageSpeed:Cost:Daily Backup:Daily backup copies all the files that you select that have been modified on the day the daily backup is performed. The backed-up files are not marked as having been backed up (in other words, the archive attribute is not cleared).Advantages:Daily Backup saves files according to your specification into a zip archive before shutting down.Disadvantages:It is time consuming.Uses up a lot of disk space.Hardware requirement: Magnetic tape , Hard disk , Optical storage , Floppy disk , Solid state storageSpeed:Cost:Incremental Backup:A "normal" incremental backup will back up only those files that have been changed since the last backup of any type. This provides the quickest means of backup, since it makes copies only of files that have not yet been backed up. For instance, following a full backup on Friday, Monday's tape will contain only those files changed since Friday. Tuesday's tape contains only those files changed since Monday, and so on. The downside to this is that in order to perform a full restore, one needs to restore the last full backup first, followed by each of the subsequent incremental backups to the present day in the correct order. Should any one of these backup copies be damaged (particularly the full backup), the restore will be incomplete.Advantages:It takes the least amount of time to perform the backup and low storage space to store the backed up files.Disadvantages:Files can be difficult to find, because they can be on several media.Hardware requirement: Magnetic tape , Hard disk , Optical storage , Floppy disk , Solid state storageSpeed:Cost:Differential Backup:Differential backup backs up files which have changed since the last normal backup. Files are not marked as having been backed up and the archive attribute is not cleared.The recovery of backed up files from a differential backup needs the most recent normal backup and the differential backup to recover backed up files to a previous state.Advantages:Recovery requires only the last normal backup medium and last differential medium.Less time-consuming than normal backups.Disadvantages:Recovery takes longer than if files were on a single medium.If large amounts of data change daily, backups can consume more time than incremental backups.Hardware requirement: Magnetic tape, Hard disk, Optical storage, Floppy disk, Solid state storageSpeed:Cost:Remote Backup:A remote, online, or managed backup service is a service that provides users with a system for backing up and storing computer files. Online backup providers are companies that provide this type of service.Online backup systems are typically built around a client software program that runs on a schedule, typically once a day. This program collects, compresses, encrypts, and transfers the data to the remote backup service provider's servers. Other types of product are also available in the market, such as remote continuous data protection (CDP).Providers of this type of service frequently target specific market segments. High-end LAN-based backup systems may offer services such as near-real-time transaction-level replication or open file backups. Consumer online backup companies frequently have beta software offerings and/or free-trial backup services.Advantages:Remote backup does not require user intervention. The user does not have to change tapes, label CDs or perform other manual steps.Unlimited data retention.Most remote backup services will use a 128 - 448 bit encryption to send data over unsecured links (i.e. internet)Most remote backup services will maintain a list of versions of your files.Disadvantages:It is possible that a remote backup service provider could go out of business or be purchased, which may affect the accessibility of one's data or the cost to continue using the service.If encryption password is lost, no more data recovery will be possible. However with managed services this should not be a problemHardware requirement: Remote backup service, broadband internet access.Speed:Cost:The most current popular backup system is Incremental backup.http://www.backup4all.com/http://technet.Microsoft.com/en-us/library/cc938473.aspxGet a new phone and what to transfser contacts from old mobile to the new one? or want to import mobile contacts to computer program, such as outlook, gmail, etc.Here I found an application called "GodswMobile Contacts Transfer" for Windows Mobile phone to transfer mobile contacts to your computer or to other mobile phones, such as iPhone and android phone.

Why is it important to backup your files?
Backup is not important to the computer; it's important to the user of that computer. Loss of data is a danger that we have to prepae for. By creating backups of your files, you can safely restore your data should anything goes wrong. This includes physical damage to the hard disk.
If a central database crashes can the information stored on it be recovered?
Yes, Commercial databases are backed up to a variety of storage places at least once a day. As some of these places are in different suburbs of the same city the comnay operates then the most information that could be lost is the information added since the last backup
