Re: [rdiff-backup-users] back up to existing mirror acting strangely

[Josh Nisly]

This is typical. rdiff-backup is checksumming each file's contents to 
make sure that the file in the mirror is the same as the source file. 
Since the data set is large, this will take a while. There really is no 
way to tell rdiff-backup to skip files whose size matches, and I think 
if you think it through, you'll agree that this is good. What if a log 
file would change, but stay the same size?

The only suggestion I have is to reduce the verbosity level, in case 
rdiff-backup is spending a lot of expensive round-trips sending log 
messages from the server to the client.
