Glacier download archive

AWS Glacier maintains an index of the archives for every vault but this can only be accessed if you initiate an inventory download job. This can take up to several hours. Firstly, you need to find the name of the vault from which you will download the archive. Then you will download the index of the vault and hopefully you will identify the archive that you want to download.

Finally, you will download the archive in multiple chunks and you will combine them. There is no way to search for your archive, you need to know in which vault your archive is. A good idea is to maintain your own index of the files uploaded to AWS Glacier.

The index could contain the name of the file, a description, the archive id generated during upload and whatever else you need to identify your file. For vaults listing you can use list-vaults command. The command will print all the vaults associated with your AWS account.

Hopefully you can identify the vault in which your archive is located. Note down the name of the vault as it will be used in many of the following steps. Having the vault name, you can then initiate an inventory download job. You will need it so as to identify the archive. Basically, you need the archive id. If you already have it in your own index , you can skip this and the next step.

Run the command, and wait. Or you can create a SNS topic that will be triggered when the operation has finished. Note down the job id, you will need it for the next commands.

If you want to check the status of the job, you can use the describe-job command. It took 3hm in my case. You can get it faster, but you have to pay more for this. The command for downloading the inventory file is get-job-output.

Actually, this command is used for downloading the output of any job. You need the name of the vault, the job id and a file name. The output will be saved in the specified file, in our case inventory. And check below how an inventory file looks like. You will get in this file the description of the archive which was provided during upload.

This can help on identifying the archive. Note down the archive id. Click image to view other screenshots. Divorce averted!! Windows Client for Amazon Glacier.
