Are these folder/file names normal?

Hi,
today I browsed through the backup data folder. Is it normal that
folders look like
/var/lib/BackupPC/pc/foo.example.org/252/f%2f/fetc
^^^^ ^
This is the backuped "/etc" folder from the foo.example.org (linux) host.
Every folder/file is prefixed with a "f" char and I don't understand the
folder name "f%2f". Doesn't look right to me.
Every backed up host shows that...
Thats perfectly normal. You will notice that file attributes are "wrong" too.
That is because the attributes are stored separat. thus the f-prefix notes that
this is a backuppc-thing. and f%2f is the notion of / in backuppc's own
"language".
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...
Of course this looks strange directly on the file-system. But you are not
supposed to use these file without the help of backuppc anyway.
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.
