We keep full backups of all data (except document scans), every 30 minutes for the last 12 months.
When cooperation is finished, we deliver a link to the last backup valid for a year.
Until 1 year after cooperation is finished and we are not obliged to store the law enforcement copies, all data are being ultimately destroyed.
There's no way to recover it back, neither we are allowed to do so.
Being able to recover old copies means we never destroyed your data - this would end up badly for us in court
