Shell Script : MongoDB Dump

I’m creating a shell script to automatically dump the database. I have the current code below.

#!/bin/sh
FILENAME=backup_`date +%m%d%y%H`.zip
DEST=/backup/$FILENAME
SERVER=127.0.0.1:27017
mongodump -h $SERVER -d "database-cms" --archive=$DEST --gzip

The problem is when I’m opening the zip file it shows a single binary file. Usually, when I dump manually it consists of bson and json files. I don’t know what I’m doing wrong I’m expecting a zip file with bson and json file.

UPDATE Turns out that –archive returns binary file. I updated the codes to:

#!/bin/sh
FILENAME=configurator_`date +%m%d%y%H`.tar.gz
DEST=/home/glenn/projects/database_dump/backup
SERVER=127.0.0.1:27017

mongodump -h $SERVER -d siaphaji-cms --out $DEST;

tar -zcvf $FILENAME siaphaji-cms

The problem is how can I specifically tar the siaphaji-cms folder. The way it runs now is when its compressing it compress all inside backup folder.

Answer

That’s actually works as designed when you use --archive.

The alternative is to provide a path to --out, which will then give you individual BSON & JSON files … you’d have to manually GZIP those (or tar the resulting subdirectory/ies.
