Which type of backup copies all files that have changed since the last full backup regardless if they have been backed up since then?
Kuraye
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.

∙ 14y agoThis is known as an Incremental backup. This is in contrast to a Full backup, which stores all files.
A daily incremental backup is recommended with a full backup at least once a week, for most systems.
A restore then entails bringing back the last full backup and applying each subsequent day to the point required.
ADSM (now Tivoli Storage Manager or TSM) uses "incremental forever" technology where every backup is incremental. It also comes with a nifty recovery tool which calculates what a snapshot would look like on a given day, at a given time. This requires constant and consistent cataloging, though, and can take some time to calculate.

How many backup copies a network server have?
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.
What type of backup that copies selected files only if they were created or modified sinece the previous backup but does not mark then as backed up?
I think you're referring to an incrementalback-up. An incremental back-up compares the files on a computer with the files on the back-up. The software only copies new or modified files to the existing back-up - it bypasses any file that already exists and has not been changed.
What are the different types of computer backups?
Copy backupA copy backup copies all the files you select, but does not mark each file as having been backed up (in other words, the archive attribute is not cleared). Copying is useful if you want to back up files between normal and incremental backups because copying does not affect these other backup operations.Daily backupA 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).Differential backupA differential backup copies files that have been created or changed since the last normal or incremental backup. It does not mark files as having been backed up (in other words, the archive attribute is not cleared). If you are performing a combination of normal and differential backups, restoring files and folders requires that you have the last normal as well as the last differential backup.Incremental backupAn incremental backup backs up only those files that have been created or changed since the last normal or incremental backup. It marks files as having been backed up (in other words, the archive attribute is cleared). If you use a combination of normal and incremental backups, you will need to have the last normal backup set as well as all incremental backup sets to restore your data.Normal backupA normal backup copies all the files you select and marks each file as having been backed up (in other words, the archive attribute is cleared). With normal backups, you only need the most recent copy of the backup file or tape to restore all of the files. You usually perform a normal backup the first time you create a backup set.
What copies all the files in a computer?
A "Full Backup".
How many Types of backup?
Five type of backup they are :1. Normal backup - It copy all the files marked in to be backup2.

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.

To supply a backup in case the original is destroyed.
Is it possible to backup programs I bought and downloaded online?
Yes, ordinary backup utilities (including those built into OSs like Windows and Mac OS X) do this automatically. You can also manually backup your files. What you cannot do within the usual licence rules is create copies to install on additional computers as runnable applications. Backup copies are fine.

Which backup type does not protect against loss of user information and data?
A system backup. This typically copies key operating system files and programs, but not user data.
Why is your Windows XP backup utility using so much disk space?
Because it copies files which you want to backup and creates a special king of archive. So if you want to backup 500 Mb you will get the archive file 500 Mb.
