I’m banging my head against this limit, my storage won’t support Linux filesystems (limited support for EXT3, a Drobo) & given one of my clients has a 4TB SSD as a boot drive, I’m forced to use a different backup software for a disaster recovery image to a local drive, then do a file backup on the resulting proprietary image over the internet, which causes scheduling difficulties, given I have to only have UrBackup do the file backup when an image by the other software is not running. I foresee this becoming an additional issue with a second client too. Not to mention complicating restore operations.
I know this is an old topic/request, but given the growth in storage time has only made it more urgent. If my storage supported btrfs I’d run a Linux server rather than Windows to work around the issue. Some way of supporting greater than 2TB images with a Windows server is becoming more of an issue as time progresses.
Even raw image format on a Windows server would do, after all, it’s possible to restore those with the Linux restore disk.
I foresee 4TB NVME drives appearing before much more time passing & people using those as a single storage/boot solution.
Sadly I’m no developer, so I can’t contribute :sad
