[rdiff-backup-users] can't backup - weird errors..

[anirudh shekhawat]

Hi there.
i have just formatted my external usb drive [160gb] to ext3 using
Gparted.following partitions were made.
sdb1  primary ext3  2gb
sdb5  logical   ext3  154gb
But when i tried to take backup of my HDD,rdiff showed following error

~$ rdiff-backup /ANISINGH/  /media/disk-1/
Fatal Error: Destination directory

/media/disk-1

exists, but does not look like a rdiff-backup directory.  Running
rdiff-backup like this could mess up what is currently in it.  If you
want to update or overwrite it, run rdiff-backup with the --force
option.

~$ rdiff-backup --force /ANISINGH/ /media/disk-1/
