The current backps are more than 800 MB in size. Need to upload this to a datastore where there is a size limit. Need to reduce the size but wanted make sure that we keep the required schema objects to ensure a successful restore.The script is using the following options.

pg_dumpall -U postgres --globals-only --file=$backupdir/globals.sql and then zip -j $backupdir/backup.$index.zip $backupdir/*.sql

The purpose here is to come back on with a zabbix set up, just in case a crash occurs. In other words what are the required schema objects that Zabbix depend on, that need to be backed up to ensure a perfect restore, ignoring all the monitored data that may be available in history and trends. Thanks for your help.
