I haven't found anything that is quite like Macrium. Mostly, because something that works the same way is a bad idea on linux. Because as you suspect, an image backup cannot be done while the partition being imaged is live.
Macrium creates restorable images of your entire boot partition or disk, as-is, which can then be restored onto the same, or an entirely different, disk.
This isn't really something you can do in linux, with a system that is live. Hence, partition images should be done offline, when the given partition isn't booted.
That said, everything that matters can be backed up simply by copying the relevant files. For this, I use Kopia.
As for making sure you always have a bootable system, for this I use Timeshift on btrfs.
For MS office, you might try winapps. Sounds like what you're hoping for.
I've never considered that a limitation.
You only need one other person in addition to yourself, for a good discussion.
If anything, here I'm finding I actually get replies, because my comment didn't drown among a hundred others.
Nono. Not bolts.
A. Bolt.
I recently switched to Kopia for my offsite backup solution.
It's apparently one of the faster options, and it can be set up so that the files of the differential backups are handled by a repository server on the offsite end, so file management doesn't need to happen over the network at a snails pace.
The result is a way to maintain frequent full backups of my nextcloud instance, with almost no downtime.
Nextcloud only goes into maintenance mode for the duration of a postgres database dump, after which the actual file system backup occurs using a temporary btrfs snapshot, containing a frozen filesystem at the time of the database dump.
It's not that kind of application. Federation would be massive overkill for a project like Mumble.
It's a voip server and client for video gaming, with a couple adjacent features sprinkled in.
It doesn't even really have accounts, and adding servers is just matter of configuring their IPs. What would you even use federation for?
Oh, it's basic af. But it did what it needed to do, and still does, for some.
I havent used it in ages, I have no clue what sort of stuff continued development has enabled. If anything.
My friend group went first from Skype to the massively better TS3, and finally to Mumble. I don't remember really missing anything.
There is also Mumble. TS3 era voip and text chat features, but it's FOSS.
You wont get windows in Grub, but since you're using separate drives, you can boot each one by just setting the boot drive in BIOS.
You can also look up how to add windows later, once you have fedora working and re-enable the drive with windows.
This should be sufficient. Go for it.
I don't think there's any effective difference between timeshift and snapper. They're both essentially just GUIs for features supported by the underlying btrfs filesystem.
Timeshift backup to another disk, is just rsync.
