[rdiff-backup-users] Restore problem

[Juan José Ivars]

Hello, i have been taking backups vía cron in that way:
00 4,8,12,16,20,00 * * * /usr/bin/rdiff-backup
192.168.40.190::/data/samba/ /data/scytale/

And clearing old removed files with:
00 00 * * * /usr/bin/rdiff-backup --force --remove-older-than 1M /data/scytale/

I am trying to list the backp history but i get that error:
rdiff-backup -l /data/scytale
Fatal Error: Bad rdiff-backup-data dir on destination side

The rdiff-backup data directory
/data/scytale/rdiff-backup-data
exists, but we cannot find a valid current_mirror marker.  You can
avoid this message by removing the rdiff-backup-data directory;
however any data in it will be lost.

Probably this error was caused because the first rdiff-backup session
into a new directory failed.  If this is the case it is safe to delete
the rdiff-backup-data directory because there is no important
information in it.

In rdiff-backup-data i only see:
ls -la rdiff-backup-data/
total 12
drwx------  3 root root 4096 jul 26 16:00 .
drwxr-xr-x 46 root root 4096 ago  5  2015 ..
-rw-------  1 root root    0 jul 26 16:00 backup.log
-rw-------  1 root root    0 jul 26 16:00 chars_to_quote
drwx------  2 root root 4096 nov  9  2015 long_filename_data
-rw-------  1 root root    0 jul 26 16:00 special_escapes


How can i recover last week files?
