Volume system formats

A volume (or logical drive) is a single continous accessible storage area, typically containing a file system. A volume system is used to manage the storage of one or more volumes.

A partition is a part of (typically) storage media. A partition is different conceptually, but its usage is comparable to a volume.

This documentation uses the term volume systems in a broad sense to describe:

• encrypted volumes;
• logical volume managers;
• partitioning schemes;
• and volume snapshots.
