An optical platter is actually two volumes because it can be written on either side - each side being defined as a volume.Volume Pool - a set (bunch, pile) of volumes defined for a specif

Tapes that belong to the same pool can be located in several robotic libraries and/or standalone.Volume Group - tapes that are defined by their location

9、(geography). Example: All the tapes that are housed in the same tape carrier. This tape carrier can be extracted from/inserted into a tape library, thus inserting/extracting a group of tapes all at once.NetBackup VolumesBackup Class/PolicyList of parameters that defines the details of how backups wi

Second file contains list of all contents (files/directories) that were backed up (along with all the permissions/dates/etc) Should exist only on Master Server (VOLUME DATABASE HOS
