Planning for MongoDB disaster recovery

You can perform the disaster recovery of the Mongo DB using one of the following methods:

Use the mongodump and mongorestore tools 

Using the mongodump tool  is an easier approach and offers the benefit of producing backups that can be filtered based on your specific needs.

• Using the mongodump tool you can perform a backup of the data in MongoDB. The mongodump tool can be used to dump:
  • an entire database
  • collection
  • or results of a query
• You can then use the mongorestore utility to restore the data to a new or existing database.
  Using the mongorestore tool you can import content from the BSON database dumps produced by mongodump and replay the oplog.

Create a backup by copying the underlying files

You can create a back up the MongoDB by copying the underlying files that the database uses to store data. To obtain a consistent snapshot of the database use one of the following methods:

• Stop all writes to the database and use standard file system copy tools,
• Create a snapshot of the entire file system, if your volume manager supports it.
