Copying the whole linux root filesystem locally or remotely using rsync

Explanation of chosen options:

• Verbose output with speed and progress information
• Try to preserve all possible information: file attrs, hardlinks, ACLs and extended attrs,
• Exclude contents of pseudo-filesystems and mountpoints
• In this example source host is remote and destination local.

rsync --info=progress2  -vaHAX --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} source.host:/ /local/destination
