mongodb backup & restore

[aizu]

Backup to folder "databasename-DATE"

mongodump --db databasename --out databasename-$(date +'%m-%d-%y')

Restore

mongorestore --db databasename --drop databasename-DATE/databasename

mongorestore --db databasename databasename-DATE/databasename

--drop : we’ll make sure that the target database is first dropped so that the backup is restored in a clean database
