Comment 3 for bug 148743

I suggest expanding the "copy partition" behaviour to include backup and restore functions in addition to the existing clone capability. If one may be permitted to add an empty tag file to one of the partitions then the UUIDs can be handled without user intervention. More detail here:-

Perhaps it is preferable not to alter the master partition in any way. The tag file could be added just to the backup partition after the copy instead.
