I have tried to understand how to perform a image system backup on openSuse 13.2 with a root btrfs file system. I have two disks on my computer, both have 13.2 systems. I would like to copy the running system with updates to the second. I do know how to backup the home xfs file system using rsync. Exactly what steps are required? My only thought is to add mount points for the second btrfs system similar to those existing in /etc/fstab? Root is a btrfs file system, with the other 14 subsystems mounted on it. 1. I originally suggested (in a previous email) backing up each of the subsystems using rsync. It was then suggested to use btrfs send/receive. 2. But what about the root file system? I believe that under rsync it will transfer data from all of the source subvolumes. How do I get that data to reside in the correct destination subvolumes. 3. If I do that, I do not see the need to individually backup the the subvolumes mounted on root as I previously had suggested. So would an approach be to add the dest volume and subvolume mount points, and then to an rsync from src root to the dest root? The reason for wanting to use rsync is that it can exclude certain files on the dest disk, such as /etc/fstab which holds the correct UUIDs for that system, /etc/hostname, the two boot subvolumes and maybe some network and other stuff TBD. I think the xfs /home would also be captured in this operation. My rsync command would look like: sudo rsync -rlpgouvtSAXHD --modify-window=60 -exclude-from=/home/.rsync_excludes / /usr11/ I have looked at the btrfs archives and can see no reference to preserving an operating system running under btrfs. Just data base type applications. I am concerned about an OS disk failure and my ability to come back to my current state in minimal time. Please have patience. As yet, I have not attempted to mount the second btrfs system similar to the first. I have searched Google etc. and thought a lot about the problem. If I am missing the obvious, please forgive. I remember back in the 80's when you could do an image copy with a single dd command:-) I am so glad we have made things so much simpler:-) Don -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
