Hello Peter,
GDPR functions will be available in 8.5 version. One of the options will be implemented (anonymizing or pseudo).
There is already new module available in last version of 8.4 called data security. There we will add all GDPR related options.
Half of requirements are already in the system: Like access rights, hiding fields, registry observations cloud security and many more.
If you're in hansa cloud, backups are kept for month and rotated. So after month, the last backup will be todays one. Backups are stored in Ireland, IBM and Amazon data centers. Information regarding where your backups are stored will be soon visible on mystandard page, when you click on "LIST OF BACKUPS".
Best Regards,
Hansaworld support
