[Duplicity-talk] [PATCH] Added command line options to use different prefixes for manifest/sig/archive files

[Matthew Lai]

Hello!

Please see attached for a patch that adds command line options to use 
different prefixes for manifest/sig/archive files.

--manifest-file-prefix
--sig-file-prefix
--archive-file-prefix

This is useful, for example, when backing up to an Amazon S3 bucket with 
life cycle rules to move archives to Glacier.

We can only move archives and not manifest files, because Duplicity 
downloads manifest files on every incremental backup.

Life cycle rules can only match prefixes, not suffixes, which is a 
little stupid, but otherwise S3 + Glacier is a very attractive backup 
destination.

I do agree it makes more sense to fix it on the Amazon side (making life 
cycle rules more flexible), but there's not much we can do about that.

PS. Someone has figured out an alternative workaround, but it's not very 
safe: http://blog.epsilontik.de/?page_id=68

Thanks!
Matthew
