Yes. Documents uploaded to projects, rooms, items, products, occurrences are hosted on AWS EFS and backup up with AWS Backup using Automatic Backup.
If a document were deleted, we can bring it back. We would need to restore a backup of the database first to find the reference to the file, then restore the file system and extract the file.
Do not consider dRofus as a document storage solution, so you should store documents somewhere else as well.
