Hi Dmitri,

WOW! I didn’t know about vchanger. I just read the wiki article about it and 
this could really change how I do disk based backup. 

I like using a NAS for bacula in the datacenter but some of my customers have 
it in their offices and this would really make things cheaper with higher 
retentions. Thanks.!!

Jeff
