How long do you keep temporary files around?
You may have noticed that Transloadit also uses
s3.amazonaws.com/tmp.transloadit.com locations for some files. This is to pass around files between uploading and encoding machines, and for debugging.
We delete these files automatically after 24 hours, so please do not rely on them otherwise.
Instead, download these temporary locations as soon as the Assembly is complete, or, even better, add an export Robot to your Templates so that files will be stored indefinitely in a place (S3, SFTP, etc) of your choosing and owning, as part of the Assembly execution.
