kindly tell me what should i do  because now i can't even take the backups

Attachments like PDFs, images, and other documents are stored in the filestore.

The database only stores metadata about these attachments (such as file name, file type, and path to the file in the filestore).

The backup size will include the database size and the filestore size. If the filestore contains a large number of attachments, it can significantly increase the overall backup size.
