Re: [Duplicity-talk] Bandwidth confusion on Rackspace Cloud Files

[Richard Scott]

Hi,

I've just ran a full backup to S3 to test and the verify option tells Duplicity 
to download data
from the remote store to verify that what we think is there is actually there.

If you try your backups without the verify check I bet it will reduce your 
bandwidth usage.

Hope this helps,

Rich
