[Duplicity-talk] mixed storage classes on S3

[hamish-duplicity]

I am backing up to S3, and I set --s3-use-ia to set the storage class. I 
am also using an S3 life cycle rule to transition the files to Glacier 
(flexible retrieval) after 120 days.

I think it would be useful to keep the metadata (manifest and 
signatures) in a different class than the data, so that I can purge my 
local cache of the metadata but get it back more readily if needed.


Unfortunately the S3 life cycle rules don't let you match by filename 
patterns, so the only way to do this is to add tags to the files (either 
when uploaded, or later, possibly with a lambda), or by setting the 
storage class differently on the files when they are uploaded. Although 
then the data would go straight to glacier rather than waiting 120 days.


Would anyone have any suggestions on this?


Thanks
