transaction A mechanism for ensuring that a set of actions is treated as a
single unit of work. Databases use transactions to keep track of
database changes.

database backups. By applying transaction backups, you can
recover the database to a specific point in time prior to when
a problem occurred.

providing a record of changes made since the last full or

the database are automatically recorded.
transportable
snapshot (Microsoft VSS specific term) A shadow copy that is created on
the application system and can be presented to the backup
