WD Anywhere Backup Interrupts Thunder bird Email Client

I have a little problem… I use thunderbird email client which I absolutely love… And i am using WD Anywhere Backup (which i also love) to backup the folder that my emails are located in…

But whenever it starts to receive emails it will recieve one… and then WDAB will start backing up the inbox folder (email folders are saved as files with thunderbird.

I’ve got into the habit of pausing the backups before opening thunderbird and resuming them when i close it so that it doesnt get interupted… my question is this: will there be a way to automate this process… is there any free software that can automatically pause the backup process when thunderbird opens and resume it when it closes?
