Description:

By default, RT stores attachments in the database. This extension
moves all attachments that RT does not need efficient access to (which
include textual content and images) to outside of the database. This
may either be on local disk, or to a cloud storage solution. This
decreases the size of RT's database, in turn decreasing the burden of
backing up RT's database, at the cost of adding additional locations
which must be configured or backed up.

The files are initially stored in the database when RT receives them;
this guarantees that the user does not need to wait for the file to be
transferred to disk or to the cloud, and makes it durable to transient
failures of cloud connectivity. The provided bin/extract-attachments
script, to be run regularly via cron, takes care of moving attachments
out of the database at a later time.
