The tapes MON - THU are overwritten in the following week, the Friday tapes only every 4 weeks. This allows you to access the data from one whole month.

You should always back up all data if the tape size is sufficient.


 

Normal backup (complete backup)
 This is a copy backup, but additionally the archive attribute is reset/deactivated. You only need the most recent tape medium to restore all your files when using this backup method.


 

Incremental backup
 An incremental backup only saves the files that have been created or changed since the last complete backup. The saved files are marked as such (i.e. the archive attribute is deactivated). When using incremental backups, it is necessary to have the last complete backup and all incremental backups at hand to restore files and folders.


 

Differential backup
 At each differential backup, the data that has changed since the last complete backup. If you use differential backups, the latest complete backup and the most recent differential backup must be available.
