Does rsync copy ACLS?

If source and destination are both locally or you can copy between them over SSH or rsync protocol you can use rsync -A to copy ACL between directories. This will copy ACL locally on same machine.

Is rsync good for backups?

Rsync is a Linux tool used for backup and file recovery. It transfers and synchronizes files between a machine and an external hard drive, or across a network. Rsync makes the process more efficient by comparing the modification dates and sizes of files, and only backing up when needed.

Does rsync preserve ownership?

rsync is much faster than cp for this, because it will check file sizes and timestamps to see which ones need to be updated, and you can add more refinements. ... You can also use rsync to copy or sync files to a remote machine, or make is run as a daemon.

What does rsync archive mode do?

This switch puts rsync into archive mode, which preserves time stamps, performs a recursive copy, keeps all file and directory permissions, preserves owner and group information, and copies any symbolic links. Archive mode gets a lot of use when you wish to make backups as opposed to just syncing files in a directory.
