When objects are streamed to or from an object server, they are streamed directly through the proxy server as well. Moreover, proxy servers are also responsible for the read/write quorum and often host inline middleware (discussed later in this chapter). • Account server: The account server tracks the names of containers in a particular account. Data is stored in SQLite databases; database files are further stored on the filesystem. This server also tracks statistics, but does not have any location information about containers.

This is done by comparing local data with the remote copy. If the remote copy needs to be updated, the replication process "pushes" a copy. The comparison process is pretty efficient and is carried out by simply comparing hash lists rather than comparing each byte of an object (or account or container database). Replication uses rsync, a Linux based remote file synchronization utility, to copy data but there are plans to replace it with a faster mechanism. Updaters In certain situations, account or container servers may be busy due to heavy load or being unavailable.
