But you will probably get errors.
The next try, will be a fake loop device, after the giant img file is made. It’ll be formatted to btrfs, which will be much better for using btrfs restore.
I think my OWC enclosure finally shit itself, and corrupted data or something. No worries, I’ll be getting another Insignia dual bay drive dock to replace it. At least those seem to work fine. Most of the stuff on Amazon is junk, so won’t test my luck there again.
dd if=/dev/zero of=backup.img bs=1G count=3000, it’ll be a while till the img file is done.
Too lazy to reboot Orange Pi 5, so the drive will mount, and I can see how much space is being used. Hopefully not more then 3 TB. If so, I’ll need another drive I guess. And the price of those slow ass 8 TB drives went up. Buying refurbished drives may or may not work. Perhaps the bigger the refurbished drive, the less likely it’ll be fine.
22 GB written so far.
Instructions for creating virtual block devices.
I wonder how slow it’ll be to mount it though. I know Time Machine on the Mac can make an image file to backup to. And that’s over Samba.
You could use qemu-nbd or whatever instead of losetup. I’ll do that, if there’s no losetup installed, should that be installed by default? No idea. Too lazy to install it, and QEMU crap is probably already installed.
41 GB, well maybe in the morning it’ll be done. The drive is shared from my Mac mini, and it’s a rugged portable drive. It has the most free space of all my drives.
I will never buy OWC anything again. Waste of money. Should have known better, I had a OWC drive that died, but putting a new drive in it, didn’t solve everything. So the drive may have been dead in it, but the enclosure is junk too. Just look at bad reviews on Amazon, and you’ll buy nothing. Better then taking a risk, I don’t want my drive to die, or get corrupted.
I should have bought another 8 TB drive, when they were still cheaper. Just wait long enough, and you won’t be able to buy it at all. Ahh all the UrBackups might be lost.
But if World War 3 is happening, data won’t be that important anyways. You’ll have bigger issues.
