Backup strategy in MongoDB

Question

I have a single node setup in MongoDB,

I currently use the mongodump which collects the mongo backup and store in another machine. But I have a scenario that If my last backup time is 12:00 PM and when the system goes down at 12:55 PM then there will be a data loss from 12:00 PM to 12:55 PM

so what is the best way to have zero data loss.

NOTE : I deployed the mongodb in Docker

Any backup strategy is appreciated.

Thanks,
Harry

I have a single node setup

There's your problem. If the only node goes down, you will lose data (if by "going down" you mean irrecoverable loss of the machine and its storage). To avoid data loss and service interruptions, set up a replica set (possibly distributed between data centers or availability zones).
