To DAMP SPECIFIC DATABASE

Syn: $mongodump --db [database name]
Ex:   $mongodump --db mongo

I t wil create a dumb file in home/dump folder with the name of mongo

The --out option allows you to specify the directory where mongodump will save the backup.mongodump creates a separate backup directory for each of the backed up databases

Syn: $mongodump --db [database name] --out [dumb foldername]
Ex:   $mongodump --db mongo --out saritha

I t wil create a backup files in saritha/dump folder with the name of mongo

To dump specific collection in database:

Syn: $mongodump --db [database name] --collection [collection name]

To zip the dump file:

Syn: $mongodump -db [dtabasename] --collection [collection name] --out - | gzip > [zip file name].gz

CHeck it in your home folder with name mongo1.gz

[or] With a date in the filename:
