A database dump contains a record of the table structure and/or the data from a database and is usually in the form of a list of SQL statements ("SQL dump"). A database dump is most often used for backing up a database so that its contents can be restored in the event of data loss. Corrupted databases can often be recovered by analysis of the dump.
These databases can be used for mirroring, personal use, informal backups, offline use or database queries (such as for Wikipedia:Maintenance).

Backup validation is the process whereby owners of computer data may examine how their data was backed up in order to understand what their risk of data loss might be. It also speaks to optimization of such processes, charging for them as well as estimating future requirements, sometimes called capacity planning.
True continuous data protection is different from traditional backup in that it is not necessary to specify the point in time to recover from until ready to restore. [5] Traditional backups only restore data from the time the backup was made. True continuous data protection, in contrast to "snapshots", has no backup schedules. [5]
