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.

Hi.  I am using rdiff-backup 1.2.5 which is what is on Leni to backup

What I am getting is  things like this in the log file:

Sometimes it says getting delta and sometimes it says processing
changed file and then copying attributes, but its never copying the
files -- as it shouldn't, but whatever it thinks its doing, its taking
a very long time and I wonder what it is trying to do and if there is
any way to get it to skip all but files whose size, etc. is actually

Thanks in advance for any ideas on this.
