Has it happened to you yet?
Floppy disk with important data goes bad?
CD or DVD with your favorite pictures got scratched?
Hard drive without any crash, warning computer does not boot?
Unless you personally experienced the loss of data, whether it is photographs, important documents, spreadsheets, databases, music files, graphics or software, you will never understand why it is so important to make backups on a regular basis to yourself.
Simply protection, the Reserve activity is the operation of copying files or databases so that they will be saved in the event of equipment failure or other catastrophe. Reserve action is usually routine, which is part of the daily activities of large enterprises with the use of computers, as well as management of business-less computers. For home personal computer users, support activities is also necessary, but usually neglected.
The search for the files you backed up is called restoration them.
In information technology and data processing, backup copying of the data, so if They need these additional copies can be restored after some type of data loss.
Backups typically used for two purposes:
1. In the event of any disaster, they are used to restore the computer to operational state after a disaster. 2. In case files have been accidentally deleted or corrupted, can be restored in small quantities files.
What are the kinds of backups?
1. Full Backup Backup all (selected) files in the system. This type of backup is essentially a waste of time, for the simple reason that in order to restore the files, the operating system must be intact and bootable.
2. Incremental backups Backup that contains only the files that have changed since the last backup (either totally or additional).
The advantage of this fast backup times, as only the changed files saved.
The drawback is the need to restore times as much as the last full backup, as well as all incremental backups to the date of the loss of data must be restored to the appropriate order.
3. Cumulative differential backup of all changes made since the last full advantage backup.
The a faster recovery time, requiring only the full backup and the last differential backup restore system.
The drawback is that for each day since the last full backup more data should be backed up, especially if most of the data was changed.
No can predict, if ever, and when his or her drive when the accident or from a floppy disk or cd will be a failure. This is not interesting when that happens, and you find out you lost data of a particular type. Specify that you are on your computer, which is extremely important for you and create a plan back files on a regular basis. Very small files can be copied to a diskette, large files can be copied to a CD or DVD. Keep a journal that you backup and when, so if you have to restore or recover a file or files, you can easily find what you need.
There numerous programs for backup and recovery of files. Most of them allow compress data to be backed up and it just saves space on the backup media. For a large number of files or very large files, it is a good way to go. If you have only a few files, and they are small, there is really no reason to squeeze them. Keep in mind that if you compress files at the time of backup, you will need the same software to unpack them, if they must be restored.
If you use software to backup files, as well as data, and then if you ever need to restore files, you can use the Windows Explorer file, or simply copy files from the archive medium on your hard disk. val eldon
