File versioning
Every time an existing file is changed, TeamDrive creates a new version of this file.
This is advantageous in the event that you need to access a previous working status or want to restore it.
At the same time, these file versions are undeletable and their content cannot be changed. Because TeamDrive also meets the requirements of the Principles of Proper Accounting (the german GOBD) by ensuring that every change to files must be archived unchangeable, certain Retention periods are subject to and must be easily verified by, for example, tax authorities
