Issues backing up dedicated SteamOS disk using ATI in Windows 11
Hello!
I actually have an official ticket raised on this (07357157); but it doesn't seem like the support folks are going to engage on my problem, which seems weird to me.
I have an Intel NUC12 PC which I'm dual-booting, between Windows 11 and Fedora, although I'm using Windows the vast majority of the time. Fedora is just for testing things. Both operating systems are sharing the same SSD, and I've been backing up the Fedora partitions on the disk for months just fine, using a scheduled backup within ATI installed on Windows.
Recently, I installed a 2nd SSD, dedicated for SteamOS. Now, I'd like to back up that entire disk using ATI from Windows. That's it. But, ATI won't do it.
SteamOS is comprised of eight different partitions on the disk. There's an EFI system partition (ESP), two small efi "slot" partitions, two root partitions, two var partitions, and a home partition for persistent data. The "pairs" of partitions come from an atomic A/B slot layout. One slot is active at any given time, each with its own efi/root/var partitions. OS updates are applied to the inactive slot, and if successful, the OS boots that updated slot. If there's a problem, there's a "known good" slot to fall back to.
Finally, the problem. ATI is choking on those two efi "slot" partitions (they are each FAT16 and 64MB in size). If one or both of those partitions are selected as part of the backup (which is using sector-by-sector mind you), ATI aborts the job with a bogus "locked volume encrypted with BitLocker" error message. My Windows partition on the other disk is indeed BitLocker encrypted, but the partitions on the SteamOS disk are absolutely not. There is no encryption used on the SteamOS SSD whatsoever.
If both of those partitions are excluded from the backup, the backups works fine. But, that defeats the purpose of conveniently using ATI within Windows, because I can't capture the entire disk. As trivial as those partitions might seem, they're important. I don't really want to use some special workaround to get them backed up independently of the ATI job. I feel I shouldn't have to do that.
Now, the rabbit hole actually gets deeper. I also have an Intel mini PC I use with our TV and sound gear in the family room. That mini PC also has two different SSDs, one for Windows 11 and the other for SteamOS. I have the same version (latest) of ATI installed within Windows 11 on that one as well, and it also has a scheduled backup task to capture that SteamOS disk. On that computer, the ATI backup works fine. All eight partitions are captured, having no problems on the same two efi "slot" partitions. The Windows disk on this computer, is not BitLocker encrypted. However, that should be irrelevant.
On the NUC12, ATI is having some sort of "detection" problem when it interrogates those two efi "slot" partitions. I would think the Acronis dev folks would be interested in fixing that, as it seems like a trivial issue to address. Do you agree, or am I expecting too much?
I do recognize that I'm probably the only person in the world, using this specific combination of elements together. But, is it really that exotic?
Thank you for your time in reading this!
