[Duplicity-talk] Archive Dir and Hosts

[AJ Weber]

It is my (admittedly vague) understanding that in my archive-dir ( 
$HOME/.cache ) for me, there are copies of signature files and information 
for the Duplicity backups.  Further, there seem to be some (if not all) that 
are host-specific.

That is, while I was testing, I used the IP Address as my target, 
backup-server.  Then I used a host-name.  When I switched between the two, 
duplicity seems to have had a much longer run and was refreshing its local 
cache or something like that.

So I have a few questions about this:

1) Is my understanding correct?  Is duplicity storing backup information in 
host-specific sub-directories and now I will have directories that will 
never be referenced again, because I switched to using a different URL (for 
the exact same target host)?

IIF my understanding is correct in #1:

2) Can we find a better way to identify hosts so that we don't duplicate 
these cache files just because the name or url changed for the exact same 
host???

3) Is there a supported (or unsupported, but safe) way to clean-up the 
directories that pertain to the hostnames I'll never refer to again in the 
URLs, but actually DO contain my backups?  Or maybe I can rename them so 
they match my latest hostname/URL?

Thanks,
AJ
