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.
Mirror backup is identical to a full backup, with the exception that the files can be compressed/encrypted only individually and only the latest file version is preserved in destination. A mirror backup is most frequently used to create an exact copy of the backup data. It has the benefit that the backup files can also be readily accessed using tools like Windows Explorer.
Backing-up is a crucial process that everyone should do in order to have a fail-safe, for when the inevitable happens. The principle is to make copies of particular data in order to use those copies for restoring the information if a failure occurs (a data loss event due to deletion, corruption, theft, viruses, etc.)
Incremental backup stores all files changed since the last FULL, DIFFERENTIAL OR INCREMENTAL backup. The advantage of an incremental backup is that it takes the least time to finish. The disadvantage is that during a restore operation, each increment is processed and this could result in a lengthy restore job.
The 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.
The Backup list is the section visible in the middle column of the main window. It contains all the backup jobs defined that can be grouped into tags for easy handling. You can drag and drop backups in the list to re-order them.
This article shows how to create a differential backup of the given sources to a specified destination using Backup4all. The current method can be extended to other sources and destinations supported by Backup4all.
