![]() ![]() Which I seem to remember don’t have Verify Copied Data set by default. They may be slightly different from the default settings. This will bring up the window shown belowīefore proceeding, I always like to set up Chronosync so it always defaults to my favourite settings. I’m currently using a temporary drive and have called it Boot Samsung 2Tb, so I know which one it is.Ģ/ Open Chronosync and click File, New Sychronizer. But any name will do, that you can identify it. If it’s not set correctly, then Chronosync will warn you that it’s not set – and will offer to fix it for you.ģ/ Rename your new Boot Backup Drive to a sensible name. Or alternatively you can allow Chronosync to do this for you. You can do this using Disk Utility – in the Utilities folder of your Applications folder. It needs to be formatted to the same type of format as your main hard drive (the one you’re backing up). The backup assistant method was actually quite easy to follow.ġ/ Plug in your external hard drive. Or you can take advantage of their Bootable Backup Assistant option. But if you have an old one lying around, it’s a great connection type.įor OX Catalina and older you can either follow Chronosync’s own guide here or follow my own steps below. Thunderbolt drives tend to be far more expensive than USB3. That’s it – drive could be Thunderbolt or USB3. It’s always kept up to date with software releases and has many options from simply copying files from one drive to another up to doing a full hard drive copy with the ability to boot from the drive. I’ve used it for many years and it’s simply bullet proof. No power leads to worry about.Ģ/ Chronosync – My favourite backup software, file copy software for the Mac. That way, if I had to take it somewhere – to plug into someone else’s computer for instance, it would be easy to do. My ideal drive would be a small portable SSD unit. More on this later, but I tried booting from a USB3 hard drive and it works, but is painful. Example, I can get a 1Tb external SSD for around £120-140, but a 2Tb version would be over £220 at time of writing.ġ/ A hard drive of at least the same size as your main boot drive. If cost were no option, one could of course have a Boot Backup drive that was way bigger than the internal boot drive. You’ll know that’s happened as the auto backup will send you a message saying backup failed, drive full. I will normally delete the Archive folder as soon as it hits its limit. But due to the drive being small (the same size as the boot drive) at some point, those archived files will fill up the drive. This will do that to a certain point, as there is the Archive folder. But by definition a backup would be a copy of the original data, with incremental copies too. This is not strictly a Backup Drive (yeah, I know, the terminology could be better). Any files that have changed since the previous night are put into a folder called Archive. So every night my computer runs an automated script (using Chronosync) that copies over my main hard drive to the Boot Backup drive. That has the ability to boot from it! So if the main drive died, you can simply restart, but press down the option key on the Mac and it will allow you to boot from the Boot Backup drive. One drive, dedicated to being a 100% copy of my boot drive. The solution I came up back then and still use to this day is a Bootable Backup drive. But not only that, even if you could remove it – what then? What would happen if the drive inside my main computer (iMac) died? One of the things about an iMac is you can’t just open it up and remove the drive. But have you ever tried restoring that data? It’s darn slow. I realised a few years ago now, when sitting thinking about backup of my computer and images, what about the boot drive? It’s all well and good having a backup of your data via TimeMachine or other. ![]()
