1. Backup of the whole database:

Mongodump-h dbhost-d dbname-o dbdirectory

-the address of the server where the h:MongDB is located, for example: 127.0.0.1. Of course, you can also specify the port number: 127.0.0.1 27017.

-d: database instance that needs to be backed up, for example: test

-o: the location of the backup data, for example: C:\ data\ dump. Of course, this directory needs to be established in advance. After the backup is completed, the system automatically creates a test directory under the dump directory, in which the backup data of the database instance is stored.

2. Recovery of the whole library:

Mongorestore-h dbhost-d dbname-directoryperdb dbdirectory

Mongorestore-h dbhost-d dbname c:\ xxx

-address of the server where the h:MongoDB is located

-d: the database instance to be restored, such as test. Of course, this name can also be different from that of backup, such as test2.

-directoryperdb: where the backup data is located, for example: C:\ data\ dump\ test. Why add an extra test instead of the dump at the time of backup? check the tips for yourself!

-drop: when restoring, delete the current data first, and then restore the backed-up data. That is to say, after recovery, the data added and modified after backup will be deleted, so use it with caution.
