To retrieve my Glacier vault inventory, The process I follow is to ask Fast Glacier to retrieve the inventory and leave it running in the background overnight connected to the internet. While this works, I wonder if there exists a client that I can close after asking to retrieve the inventory and then open it again, possibly the next day and after one or more power cycles to check the inventory.
The necessity to keep the client running prevents me form using the computer the way I want. Say I install something and need to restart my machine, I can't because then I would have to start the 8+ hour wait all over again. I am also not sure if this method is resilient to network downtime. I mean, if I lose internet for a few minutes just as the notification from AWS arrives, then do I not get it after connectivity is restored? Do I have to wait for another 8+ hours?
Also, how do you query your Glacier Inventory?
There is a multipart download you may want to look into. Its purpose is to recover from connection problems. To get your Glacier inventory, you have to submit a job for the inventory for a specific vault
