Re: [Duplicity-talk] S3 costs for PUT requests

[Russell Clemings]

I get an error with "--volsize=25M". 

What works is "--volsize=25" (just the number).

The actual parameter is --volsize, for example --volsize=25M. The --max_blocksize controls how files are split into chunks, when determining what has changed and needs to be added to the tar files.

Duplicity archives files into tar files before encrypting them, by
default these tar files are ~25MB/per, you can however change this. I'm
not sure the exact command, but, I think it might be --max_blocksize
(Note:- never tried it myself, see manpage for more info).

Duplicity also uploads manafest and signature files (Rdiff) which are
relatively small most of the time, I'm not sure how it deals with those
as I've never used the S3 backend.
