The f-prefix is called f-mangling in backuppc language.
The f%2f is really f-mangling plus %2f which is really just standard
encoding for '/' -- other special characters are similarly encoded...

backuppc-fuse mounts the backuppc backups using the fuse file system
which allows you to browse backups without the f-mangling and with the
proper file attributes and with incremental backups properly filled
using previous fulls/incrementals. You can then use standard *nix
tools to browse/access/manipulate the corresponding files.

The only downside is that it is a bit slow (but still faster than the
backuppc web interface) since each directory listing requires the
corresponding attrib file to be read, decompressed, and decoded.
