I'll have to try something like that. I avoided that because I didn't want to update the entire file. Speaking of updating the entire file, I found a major-major gotcha. When rsync copies a file without leaving the local system, it NEVER does a delta copy. In its infinite knowledge and wisdom it just does a straight copy-replace. When backing up a local filesystem to a local encrypted dirvish vault, it is important that the vault be set to a remote ip address such as *cough* 127.0.0.1 so that rsync will use deltas. I saw a reduction from 30gig a night of data change to 6 gig a night of delta changes.
