[rdiff-backup-users] rdiff-backup and file indexing software

[Jordan Thomson]

I regularly use rdiff-backup to backup a 400GB collection of files.  
Recently, I installed the beagle desktop search tool and in reading 
through the FAQ I found this:  "writing extended attributes changes the 
ctime of a file; this might cause problem if you are using any backup 
utility that compares ctime to backup changed files."

Is this something I should worry about? I.e. Does rdiff-backup rely on 
ctime values in such a way that a file indexer would cause problems? A 
simple yes or no would be great, but if someone has the time to explain 
why the answer is what it is, I'd very much appreciate it.

Thanks.
