[Borgbackup] Fwd: borg fails (I/O Error, Errno 5) to backup second Windows system to USB hard drive

[Larry Johnson]

Solved by running:
 C:\WINDOWS\system32> compact.exe /CompactOS:never
from elevated cmd on System b

-and-

installing ntfs-3g-system-compression
(https://github.com/ebiggers/ntfs-3g-system-compression)

However journalctl still shows:
Dec 03 08:30:40 KISE-005 ntfs-3g[1110]: Could not load plugin
/usr/lib/ntfs-3g/ntfs-plugin-80000018.so: No such file or directory

So I have two Windows 10 systems on separate disks/partitions.
When I use borg to backup System a (SDD) to a USB external HDD it works fine.
When I use borg to backup System b (HDD) to the USB external HDD, I
get hundreds of errors before I cancel the job, similar to these:

/run/media/ljohnson/WIN_10b/Program
Files/WindowsApps/Microsoft.Office.OneNote_17.8730.20741.0_x64__8wekyb3d8bbwe/en-gb/locimages/offsym.ttf:
stat: [Errno 5] Input/output error:

The disks look like this:

 /run/media/ljohnson/WIN_10b


System a is on /dev/sdb and System b is on /dev/sde
The USB drive is /dev/sdd

$ ls -l /run/media/ljohnson/Win10aBU | grep borg
drwxrwxrwx 1 ljohnson users    4096 Nov 30 17:25 borgBU
drwxrwxrwx 1 ljohnson users     552 Nov 30 18:28 borgBUb

Backups of System a is on borgBU and System b was to have been on borgBUb
Running on archlinux x86_64 using fuse 3.2.0-1 and borg 1.1.2-2

The run command was:

$ borg create --stats --compression zlib,5
/run/media/ljohnson/Win10aBU/borgBUb::all /run/media/ljohnson/WIN_10b/

The ntfs partitions have adequate size and check out w/o errors…

$ df -h …

No problems accessing System b using file manager
