GBase8s Core data backup
The purpose of this tool ： Sometimes customers don't back up , It is too difficult and time-consuming to repair the database when it goes wrong . This tool is to quickly deal with the fault and resume production this morning .
Backup items
Reserved page
pe
onstat -d
onstat -l
partation page
dbschema
The system tables ：sysdatabses,systabnames,systables
