Choosing a Repository Storage Backend

There is no way to migrate between repository storage backends, what you chose during setup is final, unless you start over again

S3

We recommend S3 for a few reasons:

It's what we use in production at packagecloud.io
Files have 99.999999999% durability
Highly Available

Local Filesystem Storage

However, if you can't use S3 for compliance or cost reasons, we've recently introduced Local Filesystem Storage as an option.

Very fast, as there is no need to talk to or redirect to S3
Insulated from external network dependencies/failures
