Orcle Database backup Strategy
1. Implement database Export and import by using the EXP and IMP commands.
There are three different modes:
A. User mode: Export (Import) All objects of the user and the data in the object;
B. Table mode: Export (import) All of the user's tables or specified tables;
C. Entire database: Export (import) All objects in the database.
Such as:
Normal export
A. Export a complete database

Inotify:
Inotify is integrated into the kernel. inotify is used as a third-party software to monitor directory changes through the interfaces provided by the kernel.
The inotifywait command can monitor fine-grained real-time changes to files in the directory. The monitored command is

Learn a few days of MySQL knowledge. Just get in touch with a command that is simply a grammar. But when there is a problem, I don't know where to begin.
