Hi all, Is it possible for ext3 to give a list of changed files over time? Currently we use rsync to back up our server, but it takes > 24 hours to backup the full file system. Ideally I'd like to use the file system to give me a list of files that have been created/updated and I'll back those up. Is this possible? Cheers Stuart

For me, a 5GB rsync is pretty quick --- just a few minutes, typically --- so there may be other reasons why it is taking so long. Cheers, Stephen

Also, you might want to have a look at rdiff-backup: http://rdiff-backup.stanford.edu/ It has a number of advantages over pure rsync. Regards, - Bill Rugolsky
