I used part of this to do it in a cron job:
mongodump --host 0.0.0.0 -d mydb --username mayusername --password mypassword --out /var/dbbackups/backup_$(date +%Y%m%d) && cd /var/dbbackups && tar -zcf backup_$(date +%Y%m%d).tar.gz backup_$(date +%Y%m%d)/mydb
Here is also a nice documentation to ensure, that the script will run only once simultaniusly:
This is handy! I also added an option in the output to save based on hostname, should you want to organize it in a distributed fashion.
BACKUP_NAME="$APP_NAME-$HOSTNAME-$TIMESTAMP"
according to this post of mongo DB team we can use new --archive=<name> and --gzip options to simpify script since mongo v.3.2.x
ARCHIVE_PATH="$BACKUPS_DIR/$BACKUP_NAME.gz"
$MONGODUMP_PATH --db $MONGO_DATABASE --archive=$ARCHIVE_PATH --gzip
How can you make it delete dumps after 7 days ?
Thanks man!
Thanks, Mate!!
Thanks for this... really handy
Great! Thanks
When I am running the script getting error "Failed to authenticate admin@trzprod with mechanism MONGODB-CR: AuthenticationFailed key mismatch"
Please help me out this
How can you make it delete dumps after 7 days ?
The command below will only save for newest 7 files.
ls --color=no -t | sed -e '1,7d' | xargs -d '\n' rm
That great @yueyericardo, How we can save 15-day dumps in S3, older should delete automatically.
please let me know and I want to add the lines to exiting the script

Hi, simply add this to the end of script.
# only keep the newest 15 backups
cd $BACKUPS_DIR
ls --color=no -t | sed -e '1,15d' | xargs -d '\n' rm
please let me know and I want to add the lines to exiting the script

There is one little error make this line
rm -rf $BACKUP_NAME`
to this:
rm -rf $BACKUP_NAME
Otherwise it script broken on line 24.
However, thanks for it. 👍

Hi @serverguru666, just wondering does mongoDB authenticationType have anything to do with this error that i get when i try mongodump using your connection format -
2020-05-31T23:53:02.921+0000 Failed: can't create session: could not connect to server: connection() : auth error: sasl conversation error: unable to authenticate using mechanism "SCRAM-SHA-256": (AuthenticationFailed) Authentication failed.
NB: The issue is that the command doesn't want me to add --password as plaintext, if i remove the --password flag it prompts me for password and works ok.
How to delete after 1 week please let me know..
Make it executable:
Schedule a Cronjob:
Enter this in a new line:
