Hi @Lucas Escudero ,
Welcome to Microsoft Q&A!
it tells me that it cannot find the destination where it was saved
That means that the previous backup file is deleted along with the disk. If your database is fine, you should make a new backup on an available disk right away.
If you are using SQL SERVER, DBCC CHECKDB can help you check if there are any problems with the database.
Best regards,
Seeya
