[rdiff-backup-users] can't --remove-older-than on Mac OS X

[Vinod Kurup]

Hi,

I've just recently started using rdiff-backup and love it so far. I was  
successfully backing up from Debian Linux to Mac OS X using  
rdiff-backup 0.12.6, but the Debian distro upgraded to 0.13.3 and then  
I started having trouble with the --remove-older-than flag (even after  
upgrading the Mac OS X side to 0.13.3). I've narrowed down my problems  
to the Mac OS X side - Linux-to-Linux works fine.

Here's the simplest test case I can make. I downloaded the latest CVS  
this evening.

I make a directory with one file in it. I back up that directory. I  
restore that directory. To this point I have no problems. When I try to  
run --remove-older-than on the backup directory, I get an error. I've  
done a little debugging and it looks like the date-stamp in the  
current-mirror file isn't getting unquoted properly. Here's the step by  
step with -v9:

destination side

The rdiff-backup data directory
vk-backup/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.

Please let me know if I'm doing something obviously wrong, or if I can  
supply more useful information.
