Click the backup destination icon, select where you want to save the backup file, click OK. Click the backup source icon and select what whether you want to back up disks or files and folders. Click Add Backup at the bottom of the backup list. How to Backup Mac to a Local Drive or Network Storage.
![]() ![]() ![]() Setup A Backup Drive Movie Or WhateverNew local and network Time Machine backup destinations are formatted as APFS by default. The Apple documentation indicates:APFS-formatted backup volumes are now supported for faster, more compact, and more reliable backups. It only prompts if it has a different format than HFS+ or APFS, and then it formats as APFS by default. At least with the beta versions that I tested, Time Machine in Big Sur does not reformat or prompt to format other way if the selected Time Machine is formatted as APFS. I think that it can be checked doing a “Time Machine – Back Up Now” (and inspecting the used disk space in the Time Machine disk) and then opening a large virtual machine, closing it (or changing a bit a large file like a movie or whatever), selecting again “Time Machine – Back Up Now”, checking the amount of data and the time that it takes in the “Time Machine – Open Time Machine Preferences”, and the final used disk space whown in the Time Machine disk.2. Microsoft office 2011 for mac includesUse T2M2, as it actually provides all that info without having to run a non-auto backup.2. After all, that is the main advantage of APFS for backups.1. If the Apple documentation is right, then Time Machine in Big Sur should copy only changed blocks, and not the full (usually huge) Virtual Machine files. SuperDuper and Carbon Copy Cloner (CCC) also work fine with them.4. I have restored from them without problem. My experience in the past is that Time Machine also backups fine virtual machines. If you care to study TM logs, you’ll be surprised at how little is backed up by blocks. Time Machine doesn’t address that.4. This is a well-known problem for those who back up active VMs on all platforms. That may well mean that your backup VM is broken. Are those VMs which are in use at the time of the backup? Whatever your experience might be, that’s a recognised problem, as the VM may well change while the backup is being made, which means that first part of the VM reflects its start at the start of making the copy, and the second part may well be changed. In any case, it’s irrelevant: if you want Big Sur to back up to APFS, follow the instructions that I have given, and format the disk in APFS before setting TM up.3. Even if TM->APFS were to address some or all of them, wait until this is clearly established, or you could be very disappointed. In any case, this still doesn’t solve the problem of the VM changing while the backup is being made, does it?Moral: if you need to back up VMs, make separate arrangements which address their peculiar problems, and exclude them from TM.
