For the moment, I use rsync for linux copy/clones/moves from source to target partitions for the same hardware, and it works. I do these steps: (1) Boot with LiveCD (2) # rsync -ahHAX <source> <target> Notes: (a) Optionally add 'z' argument if you want compression and add 'v' if you want to see verbosity at the expense of transfer speed. (b) Abruptly stopped? No problem, run the above command again. (c) <source> and/or <target> can be remote devices but they have to be mounted. The <source> ought not be an active running OS, can be mounted to /mnt via LiveCD. The hardware for the <source> & <target> ought to be exactly the same if one expects the <target> OS to be bootable after transfer has completed. I have done this with (a) remote backup source to target and (b) between two identical laptops transfers via LiveCD on both, and it works. (d) I have not tried to create an rsync "image". If it were possible to create an rsync "image" with with FULL acls/permissions/..., how would it be possible to perform an rsync "restore"? I have not tried this. (3) Setting MBR on boot or / (boot integrated) partitions: # grub find /grub/stage1 (or /grub/grub.cfg) root (hX,Y) setup (hX,Y) quit (4) # touch /.autorelabel; reboot (for SELinux) FWIW, Dan -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
