![]() ![]() ![]() Lots of holes in that analogy, but it sort of works. So the donut is only intended to get to where you can repair/replace the bad tire, where the full size is actually capable of being a full replacement. You can drive, but much slower and without the handling. A TM backup is a bit like the "donut" spares that are smaller and only designed to be used in an emergency to get to a garage to have the flat repaired. Get the flat repaired, put it back on and the spare goes back in the storage space. Get a flat, change the tire to the spare and drive just as normal. Just recovery.ĮDIT: Just thought of a rough analogy: A Clone is like having a full spare tire in your car. If you have a TM or TC backup, you can boot, but only to the Recovery screen where you can use Disk Utility to format or repair the internal, then reinstall the OS and trigger a recovery from the TM into that new drive. It will be slower, particularly if it's a rotating drive and the internal was an SSD, but it will be functional. You can check mail, surf the net, use the system just as if the external was the internal drive. To illustrate, if you have a CCC clone and the internal fails, you can boot from the external and use it while you order a new internal drive, install it, then format it and clone back to it. But a TM boot cannot be used as if it were the drive itself. TM can be booted, but only into Recovery, from where the OS can be reinstalled and then the backup restored. My second question was to have been 'Can I continue to back up both iMacs to the same drive?' Judging from the messages I'm getting I suspect that the answer is no.Ĭlick to expand.Not sure what you really mean by that. I think that the backup that I attempted last month failed, presumably because it wouldn't do a Big Sur backup. I've now connected it the 2017 iMac and my previous backup seems to have vanished but hers is still there. I connected it to the 2011 iMac and got a message saying that it is incompatible. When it says destination does that mean that the whole of the external hard drive has to be erased or just the partition relating to one of the 2 iMacs? Bombich says " This utility does not offer as much flexibility as you've grown accustomed to with CCC on older OSes, in particular it requires that the destination is erased and that everything is copied from the source to the destination." I have backups on a 1TB external hard drive for my wife's 2011 iMac with High Sierra and for a 2014 iMac which I am in the process of selling loaded with Catalina. But AFAIK, this is not yet supported.I have read CCC's comments re the above. And it would be really nice if one could use Carbon Copy Cloner to backup to a NAS device, such as a QNAP or a Synology via rsync. You must instead set it up in the first task. For example, if you want to run a script first thing, you cannot set that up in a task group. With a bit of practice, you will master it.There are some things that you still cannot do in task groups. It seems to work best if I drag the task just to the bottom of the task group. It doesn’t work well if I release the mouse button with the task directly on top of the task group. That is you cannot put one task group inside of another.The option dragging is a bit tricky. AFAIK, there I no way to nest Task Groups. And well worth the upgrade price, there are still some ways in which 5.0 is a “dot zero” release. )Not Yet Perfect:While it is very, very good. So you don’t have to become an expert on rsync filter rules. So you no longer have to do some of those ugly workarounds like running your tasks in less than desirable orders, or figuring out how long each task will take so you can “choreograph” them by careful selection of starting times.For copying remote Macs, you now have a really nice GUI interface for filtering what you copy, and what you don’t, that is very similar to what you have for filtering the copies of local volumes. This meant that you had to create different tasks that were identical, except for the task they called to run after them.Task Groups free one from these issues. By option dragging a task from one task group into another, multiple Task Groups can contain the same task.The old approach, chaining tasks, was limited because chaining required that the sequence be the same each time or you couldn’t reuse it. A task group can contain an assortment of tasks to be run in a particular sequence and scheduled as a group. Version 5 contains some very significant upgrades, particularly if you have a sophisticated backup configuration, or backup remote Macs.ProsVersion 5 allows the creation of Task Groups.
