Download your Synology Glacier archives in Fast Glacier.

The Synology DiskStation Glacier app only allows you to download an ENTIRE Glaicer vault if you want to do recover files. That's lame!
[FastGlacier] (http://fastglacier.com/) is a Windows application that allows you to download individual files from Amazon Glacier repositories.
This program converts the data that is stored in the DiskStation into a format that FastGlacier can read, thus allowing you to download individual files that were stored by the DiskStation Glacier app.

Requirements

Do an inventory request via FastGlacier to retrieve the vault archive listing
- FastGlacier stores the archive listing under
  /Users/<user>/AppData/Roaming/FastGlacier/cache
- Find the cache sub-directory and file which matches the vault in question. The names of these folder and files aren't human readable, so if you have more than one you can identify the correct file by opening the files in a text editor and looking at the VaultARN at the beginning of the file.
Synology Glacier Sqlite DB
- If you have shell access to the DiskStation: The DB is typically found in the /var/packages/GlacierBackup/target/etc directory with a filename like <diskstation_glacier_backup_task_name>.mapping.db. Copy this file somewhere else for backup. This program does not modify the contents of the DB, but it is safer to operate on a copy of the DB rather than the original.
- Or Do a Download request in FastGlacier for the single file within the Diskstation_mapping vault. This is the same sqlite DB as is stored on the DiskStation.

node run.js --db <path_to_sqlite_db> --vault <path_to_fast_glacier_vault_cache> [--out <file_to_write_modified_vault_output>]

By default this library will write to a file with name <path_to_fast_glacier_vault_cache>.new, but always backup your original files, to be safe and save time if something goes wrong.
Overwrite and replace the original FastGlacier cache file (after backing it up!) with the newly generated file. You should now be able to see all the correct filenames in FastGlacier after a restart.
