Dear All,



Please help me, I want to ask how to make a menu for Backup and restore the data from the table?

Suppose a table with the name "tb_User", in the table there is data such as name, level (admin / user), etc.
The table will be backed up, but only to the level name "user" who is in the backup.

If the data in the table already in the backup, how to restore these backups?
Format backups, can sql or xml, or whatever lah.

Please help, thank you
