MongoDB Backup and Recovery

Mongodb Backup and recovery

First, Create a library, and then insert the data

Then make a backup:

The first thing to do is to erase the database and the data.

Then recover the data:

The data has been restored back

Create a library again to insert data

Then back up

If you want to recover, delete the database first and then restore

If you want to restore a single collection and backup:

One, collection backup

Mongoexport-h collection where server address-D database-C collection-O Local file storage location

Note: File format is optional json, CVS, etc.

Official Number Description:mongoexport--help

Second, set restore

Mongoimport--host Destination IP--port destination port--db target database--collection Destination collection--file backup file location
