== Usage ==To create a new backup, we need to create a new backup task that will allow us to configure what files are being backed up and various configuration settings. Choose + to create a new task. Give it a name. Click on the Archive option in the left hand menu of the New Task dialog as shown in the image below. Choose 7zip and compress files individually. Cobian Backup uses the archive bit of the attributes to check if the file has been changed or not. Sometimes the program fails to change the attribute and the file will be copied again next time even if it is not necessary. The archive attribute operation can fail for example if your source is in a Linux or other system that have different attribute formats or if the engine doesn't have permission to change the attribute. === Incremental ===The backup software creates copies of all the files, or parts of files that have changed since previous backups of any type (full, differential or incremental).An incremental backup includes only those things that have changed since the last backup, and saves those things into a separate, additional, backup file or location.All the incremental backups must be available to perform the restore. For example if you did a full backup on Sunday. An incremental backup made on Monday, would only contain files changed since Sunday, and an incremental backup on Tuesday, would only contain files changed since Monday, and so on.Restoring from incremental backups is the slowest because it may require several sets of data to fully restore all the data. For example if you had a full backup and six incremental backups. To restore the data would require you to process the full backup and all six incremental backups.This is the feature you will most likely be using after creating your first backup instance. It checks if the source has changed from the last backup and only will backup those files that are new or have changed since the last backup. This saves a lot of time and space on your PC or the medium you will store your backup upon.
