Have you tried re-flashing WITH a settings restore?

YES

Dear all,

got a problem when using ImageBackup on NFS drive (but OK on USB-drive):

Platform: Vu+ Duo 4K SE / OpenVIX latest
Reproducible: 100% on NFS automount with root_squash

Steps:
1. Set backup destination to NFS automounted path
2. Run Image Backup

Result:
- imagebackups/ created with drwxr-xr-x (ok)
- imagebackups/openvix-vuduo4kse-release-mount: drw-r--r-- (WRONG - missing x bit)
- imagebackups/openvix-vuduo4kse-release-temp: drw-r--r-- (WRONG - missing x bit)
- Backup fails with makedirs/permission error in doBackup1

Root cause:
os.makedirs() called with mode=0o444 instead of 0o755 for temp/mount dirs.
On local disk root ignores permission bits — bug is invisible.
On NFS with root_squash, mapped UID cannot enter directories without x bit.

Fix: Change makedirs mode to 0o755 for mount and temp subdirectories.

Can one please direct me in the right direction? Would like to get this issue fixed, since I run a diskless receiver

best regards

The problem is in def doBackup1 in ImageManager.py.

It calls mkdir() twice with 0o644.
And makedirs() 3 times.

I'm sure @twol will check and commit your fix @birdman. He's done a lot of work on ImageManager. Thanks for detailed report and suggested solution @birnbam

Thanks a lot for the quick fix
