Funny you should mention rsync. That's what I'm using to copy recent files.
You have to run root (sudo) to so some things (like preserve user/group/mtime). And in my case, to not get nagged about not being able to change user/group it needs user map and group map parameters. (Shouldn't be necessary going to ext4.) What I ended up choosing was sudo rsync -avc --usermap=*:paul --groupmap=*:paul source-dir dest-dir Obviously do n for trial run till you're sure. The checksum option obviously takes quite a while for it to start, but not choosing checksum, rsync wanted to copy every file, regardless. I'm guessing some difference in mtime storage? Idk. The user and group mapping were the last thing I set so possible it was something with that. ---Paul.
