it seems our backup directory has some problem with rdiff-backup-0.12.5:

thanks in advance.



Looks like your metadata file got corrupted.  You could try deleting
it (move it aside for safetly), or follow the advice at:

http://rdiff-backup.stanford.edu/FAQ.html#regress_failure
after I delete the current_mirror.xxxx and try to backup again, I've got this. does this means I loose all of my backups? this happend 3 of our servers: 
-------------------------------------
rdiff-backup --print-statistics --ssh-no-compression --include-globbing-filelist /etc/rdiff-backup/portal portal-backup::/ /mnt/backup/portal 
Previous backup seems to have failed, regressing destination now.
