No.	Term	Description
1	Full backup	DBS splits the data of all tables in a database and executes SQL statements on the database to read the data in multiple threads in parallel.
2	Incremental backup	DBS incrementally backs up logs stored in the memory of a database in real time. This prevents the sudden I/O performance drop that may occur when a full backup is performed on a large amount of data. The speed at which database logs are read also varies based on the rate at which they are generated.
3	Database disk space	The total space consumed by data files, logs, operating system files, and the available space of the operating system of the server where the database resides.
4	Backup data size	The amount of data backed up by using Database Backup (DBS). This size depends on a variety of factors such as the database type, backup mode, and backup granularity.
5	Storage data size	The volume of data stored in the storage system. This size depends on a variety of factors such as the backup data size, the storage format of backup data, and the compression algorithm.
