Hi, I looked though documentation and also checked last 9 months of archives, but could not find the corresponding information. We are having an issue with incremental backup with arkeia. Arkeia checks if ctime/mtime of the file are changed, if so, it backs up. I realized that when I ran rsync from a cammnd line, it changed ctime, and preserved atime of the file in a destination as follows even though a file has no change in its content. Is this a expected action for rsync ?
