JENIS2 BACKUP
1. Normal Backup
2. Copy backup – salin semua fail sahaja (e.g fail, lagu), tapi
3. Daily backup
4. Incremental backup
5. Differential backup
6. Data migration – semua yang ada dalam pc lama, akan dibawa ke pc yang baru…contohnya kita beli pc baru, barang banyak dalam pc lama, jd proses ini adalah sesuai.
Normal backup (http://www.ucertify.com/article/what-is-normal-backup.html)
Normal backup is a type of backup specified by the Windows Backup utility. When an administrator chooses to use a normal backup, all selected files and folders are backed up and the archive attribute of all files are cleared. A normal backup does not use the archive attribute to determine which files to back up. A normal backup is used as the first step of any backup plan. It is used with the combination of other backup types for planning a backup strategy of an organization. Normal backups are the most time-consuming and are resource hungry. Restoration from a normal backup is more efficient than other types of backups.
Copy backup (http://www.backup4all.com/kb/copy-backup-380.html)
Copy backup is a backup that copies all selected files but does not mark each file as having been backed up. In other words, the archive attribute is not cleared. Copying can be carried out between normal and incremental backups because copying does not affect these other backup operations.
Daily backup (http://www.backup4all.com/kb/daily-backup-321.html)
Daily backup refers to making daily copies of data so that these additional copies may be used to restore the original after a data loss event. Daily backups can also be combined with weekly or monthly full backups, according to the backup scenario used.
Incremental backup (http://financialsoft.about.com/od/glossaryindexi/g/IncrBkup_def.html)
An incremental backup is a backup of data files that have been changed since the last full or incremental backup. To contrast, a full backup backs up all file, whether they have changed or not. Incremental backups save disk space and time since not each and every file is backed up.
Differential backup (http://www.backup4all.com/kb/differential-backup-117.html)
Differential backup contains all files that have changed since the last FULL backup. The advantage of a differential backup is that it shortens restore time compared to a full backup or an incremental backup. However, if you perform the differential backup too many times, the size of the differential backup might grow to be larger than the baseline full backup.
