-CO[NVERT]
Convert external tables to normal tables.
This switch causes any external tables to be backed up as if they were normal (non-external) tables.When this backup file is used to restore a database, the tables that were external in the original database will now be normal tables.
-E[XPAND]
Do not apply RLE compression on backup data.
Normally, gbak
will compress the output file.This switch prevents that compression from taking place.
This is a very basic RLE compression with a low compression rate, for better compression, use [gbak-cmdline-zip].
-FA[CTOR]
Blocking factor.
-FA[CTOR] block-size
If backing up to a physical tape device, this switch lets you specify the tape’s blocking factor.
