A normal full backup 

With a copy backup  all selected directories are saved without marking the files as such (the archive attribute  remains unchanged). A possibly existing backup file ist deleted prior to backup. With this backup method, you only need the most recent complete backup to be able to restore all files.
 

Differential backup

With differential backups , the first backup is a complete backup. After that, at each differential backup, only the files that have changed since the last complete backup are saved.

Incremental backup

The first backup with incremental backups  is a full backup as well. After that, the files that were changed since the last incremental backup are saved at each backup.

New complete backup all XX days

When this option is activated, Z-DBackup automatically switches its backup method according to the specified interval between full backups and differential / incremental backups. After 1 to 99 days of saving only new or changed files, it will create another full backup.

  To create a new full backup with a backup set for differential or incremental backups, you can also create a desktop shortcut  with the "full backup" parameter or create another job in the Z-Cron scheduler!

 Data synchronization

 If this option is activated, only files which are new or newer than those in the backup directory are saved. Reference point is an existing backup file. If no backup file exists, the original file ist copied.
