User data, which has been backed up is physically stored on the hard disk, until they are being removed by a storage cleaning tool. Only the data that has been deleted by the user in the Xopero client application are subject to removal by the mentioned tool.
After deleting data in one of the above-mentioned applications, data in the storage is marked for deletion and finally deleted after 24 hours after being marked.
If the user wants to delete the data from the storage earlier, he can use the Storage cleanup option, which will start the cleanup process.
The Storage cleanup option is highly overloading the drive, so it is best to run it at the time of the lowest usage.
