We currently have a Unix server which has a Progress 7.3 database on it. The database is shutdown and backed up on a weekly basis.
Recently I have found out from the systems support team that the database takes along time to back up due to it having to backup even the empty extents, which are backed up as if they were full.
I understand that the database is allocated a certain amount of space through one or more extents which in their elementary sense are disk files sitting in a filesystem but if an extent is empty and is being backed up surely there are no blocks to send to the tape drive?
Is an empty extent purely just space in the filesystem reserved/allocated to a database not a full block of data bytes?
I'd be grateful for any help on this matter.
