My messages on the MBP are not synced to the iCloud. Many of my messages on my iPhone which are linked to the iCloud have disappeared over the last month or so. I would like to enable iCloud sync on my MacBook since most my messages are still present on this device, however before enabling iCloud sync on my Macbook I would like to make a copy of the messages folder incase the sync mirrors the messages of my iPhone which I don't want it to do and to be able to revert back if the sync doesn't work out . Is this possible? Thanks.
