Backup checkpoint

,

I need to take full backup of mongodb/mysql which has around 1TB. Consider that backup process got failed almost at the end of it (say 90%) and if we start again from starting point it would cost more in terms of money as well as time.

Any ways to handle this situation? I mean, any solutions where I can restart my backup process from the point of failure?

Hello, unfortunately I am not aware of any way to resume a failed backup.

Hi, thanks. Even I am not getting any solutions for this task. There must be some ways to do it, not in Percona but in MongoDB side itself we may have some answers.

Think about the backup process and how it performs it. The backup acquires lock for consistency, when it fails the lock is released. Think about this , even you could restart the backup, can you guarantee the consistency? and that’s the answer to your question.

What you want to do is something on filesystem level, like using rsync and you can restart that think :slight_smile:

thanks. Yes, surely will look into it. As I am new to mongodb, can you please tell me how a backup process works (in-depth) when we execute mongodump ?
