# Toucan 1.1 Help - Backup

1. The source and destination boxes arae where you set the paths required for the operation. The buttons on the right allow you to select a file or folder, depending on what is required.
2. The insert portable variable buttons allow you to easily add portable variables without having to type them.
3. The Save and Open buttons allow you to save all of the information on the screen so that you can easily use it again. You also need the saved jobs for the command line interface.
4. The function select box allows you to choose which type of operation to carry out. The Complete option backs up all of the files in the source folder (bar any excluded files/folders) to the archive. Update adds any newer files to the archive and Restore extracts the files to a folder of your choice. The first time you run an incremental backup a complete copy of the source folder is put into the destination folder. On subsequent runs only new or modified files are stored in a second archive. This way you only have to do a full backup once.
5. There are currently two supported archive types and you can select which one you are using/going to use here. Zip files are larger than 7zip files but are generally much faster to compress.
6. The final option is the level of compression and is only relative in the Complete and Update options. The Maximum option will take as much as ten times as long to compress than the Normal option.
7. The exclusions box allows you to ignore file types and folder names from the operation. To exclude a folder simply add its name (e.g. App) and to exclude a file type add its extension with the leading dot (e.g. to exclude programs add '.exe' without the quotes).
