Proxmox-backup-client failed : Error: EACCES: Permission denied (500)

[Frenshow]

Hello guys !



I rely on you because I have a problem !



I have 4 servers on which PBS is installed. On this 4 servers, two of them can no longer connect to PBS and their storages went to the status of "unknown" and when I go the "backup" tab, I read this error message : "proxmox-backup-client failed: Error: EACCES: Permission denied (500).



I would like to know what is the problem with this two servers.



Thank you !

hi,

can you please post the contents from journalctl? it might be wrong file permissions or ACL

 

[Frenshow]

This is the journalclt, I hid the path. This is a new error.

you don't have permissions to write on the datastore. you should check the file owners and permissions where it's located and make sure backup user can write to it

 

[Frenshow]

I changed permissions, I wrote "chmod 700" and its doesn't change !

 

[Frenshow]

I wrote "chmod 777" and its seems ok.

Thank you !

chmod 777

this gives write access to all users on the system to write to the datastore!

you should rather set the owner with the chown command to backup:backup.

like so:

chown backup:backup -R /path/to/your/datastore
chmod -R 600 /path/to/your/datastore

so this will set the owner to backup and make the permissions more restricted, it should be a safer solution that giving 777

I tried and it doesn't work. It work when the owner is root with "chmod 755"

 

[oguz]

ok that should also be fine

 

[Frenshow]

I tried and it works with the backup owner and with chmod 755, not 600, its weird isn't it ?

 

[oguz]

i guess it needs 700 at least, so the backup user/group should have all the permissions (read/write/execute)

Ok thanks, I will try !
