Permission problem when installing Backblaze on Unraid

[TherkelMJ]

I'm having some problems with the backblaze_personal_backup docker on Unraid.
It looks like it doesn't have permissions to execute the exe file it downloads.
But when checking permissions for the "C-drive" where i assume it downloads it, i beleive it looks fine?

root@ZeSmallOne:~# docker exec --user app backblaze_personal_backup ls -la /config/wine/dosdevices/
total 12
drwxr-xr-x 1 app app 12 Feb 2 18:41 .
drwxrwxrwx 1 app app 126 Feb 2 18:40 ..
lrwxrwxrwx 1 app app 10 Feb 2 18:39 c: -> ../drive_c
lrwxrwxrwx 1 app app 9 Feb 2 18:41 d: -> /drive_d/
lrwxrwxrwx 1 app app 1 Feb 2 18:39 z: -> /

This sounds similar to what I'm troubleshooting in #81

Ye looks like you're right :)
Just tried setting USER_ID and GROUP_ID to 0, and then it works, so I guess it's purely a permission problem, and not a network problem.
Now i just got to find a user that isn't root, with permissions to run it

Hello!
you are totally right, it's a permission issue. You can either create a totally new user just for backblaze on your system.
It has to have read-write permissions on the config folder where the container installs Backblaze to, and it need read-write permissions on all shares which you'd like to back up (Backblaze creates a .bzvol folder at the root of the shared folder / directory with infos that it can identify the drive and check its on/offline state).
Hope that helps!

I've submitted a pull request #110 that writes the download to /tmp rather than / when it's a new install (as well as fixing the log_message errors.

If someone can review and approve the pull request, I believe these will solve the access denied issues without having to change USER_ID and GROUP_ID

@traktuner @JonathanTreffler @xela1 I've commented in issue #81 that I wonder if this is due to unRAID not really having a user system like other distros for their docker system. They usually ask that dockers support PUID and PGID settings so that they can implement PUID (99) and PGID (100) in their templates so root doesn't need permissions.

@TherkelMJ can you test again with tessypowder/backblaze-personal-wine:ubuntu22 see if that stops the permission denied errors without changing user id

This fixed my issue!

Glad it works for you now - thanks for reporting back!

I would like to add that by using the ubuntu22 tag on unraid I can too access everything and backup fine now without adding UID and GID of 0. I am getting another issue of "your Backblaze client installation is not correct!" popup but I'll search the forums here to see if theres a thread for that since this thread is closed. Thanks!
