Possibility of POSTBACKUPERROR? (Command to run if backup failed) Or way to achieve this behaviour?

[josephrocca]

Hello! Currently we can run a command when the backup finishes with the POSTBACKUP option. I'm wondering whether there's a way to run a command specifically when the backup fails, or if there's some way to detect if it failed from within the POSTBACKUP option?

My use case is: I have no idea how to set up mail on my server, and would like to use a simple nodejs script like this:

require('nodemailer').createTransport('smtps://blablablabh.com%40gmail.com:[email protected]').sendMail({to:'[email protected]', from:'automongobackup', subject:'automongobackup ERROR - check your logs!'});

I'm a bash noob, so if this is not something that's achievable, that's cool - I'll try wrangle together some workaround. Thanks!
