Our Glacier archive description metadata is a simple JSON with the following fields:
- "Path": the full path of the source file. E.g., "c:\myfolder\myfile.txt" for file copied from local disk or "mybucket/myfolder/myfile.txt" for files copied from cloud storage like Amazon S3. The path is UTF7-encoded.
- "UTCDateModified": ISO8601 utc date without milliseconds (format: "yyyyMMddTHHmmssZ"). This is modification date of the original file (not the archive creation date).
- "Flags": integer flags value. 1 - compressed, 2 - encrypted.
Thanks, Andy
