level 0 backup is full backup

Answer / manivasagam krishnan

Level-0 backups can be time-consuming because ON–Bar writes
all the disk pages to backup media. Level-1 and level-2
backups might take almost as much time as a level-0 backup
because the database server must scan all the data to
determine what has changed since the last backup. It takes
less time to restore data from level-0, level-1, and level-2
backups than from level-0 backups and a long series of
logical-log backups.
