Garbage Collection (Performing a full backup using IBConsole)

From InterBase

Option values are True and False.

By default, IBConsole performs garbage collection during backup. To prevent garbage collection during a backup, set the Garbage Collection option value to False.

Garbage Collection marks space used by old versions of data records as free for reuse. Generally, you want IBConsole to perform garbage collection during backup.

Tip: Disabling garbage collection during the backup process improves backup performance. If garbage collection is necessary, you can run a separate sweep operation using gfix. In addition, you do not want to perform garbage collection if there is data corruption in old record versions and you want to prevent InterBase from visiting those records during a backup.

This function corresponds to the -garbage_collect option of gbak.
