Swift stores the data we store in the containers in .data foramt in the corresponding Drives.

In above out put the swift drive is mounted to /srv/node/sdc1.
we can get the date when the data file is created from the name of the data file.

If we have enabled 2 replication is the swift ring configuration there will be two data file with same name. If we have multiple swift server's the replicated data will be stored in different server's rather than the same server.
