[Dirvish] Updating/overwriting existing images

[Samuel P Howard]

Hi.

I have a little script set up to automate the running of the "dirvish 
--vault {foo}" jobs, and sometimes the client pushes a new dataset to 
the staging area for dirvish to backup.

However, the configuration is set up for only 1 image per day.

So, is there an option for updating or overwriting an existing image?  I 
haven't been able to find it, but then again, I may be blind, too.

As an alternate, I thought of checking the return code, but the RC for 
running a dirvish --vault for an image that already exists comes back 
with RC=224.

224 is in the 220-254 range ("An error was detected in the 
configuration."), which I wouldn't consider a very accurate description 
of the reason for the failure.

Something like "Image already exists" might be nice.  :)

The only option I currently see is to attempt the dirvish command, if it 
fails with a 224, remove the existing directory and re-create it ... 
somehow, I think that will bite me down the road with the indexes, 
however.  Also, since 224 is range that sounds more like the config file 
is broken, I wonder what other conditions could return that error code?

Any ideas?

Thanks,
Sam
