zmbackup to remote smb share fails with permission error

[gnyce]

Here is what I get:

[zimbra@mail oldusers]$ zmbackup -f -a someuser@meritgames.com -z -t /mnt/smbbackup/oldusers/

Error occurred: system failure: Unable to create directory /mnt/smbbackup/oldusers/tmp/full-20090107.195815.073/sys

I thought it was a permissions error... still might be... but I have it worked out such that the zimbra user/account has permissions, and any newly-created directories have world-writable flag. Zmbackup is able to create the "sessions" and "tmp" directories, and sometimes even the full-* directories, but never past that. So, am guessing that zmbackup drops permissions somehow? Even so - not sure how much more 'lax' I can make this... suggestions?

[zimbra@mail someuser]$ ls -lr
drwxrwxrw- 3 zimbra nobody 0 Jan 7 14:58 tmp
drwxrwxrw- 2 zimbra nobody 0 Jan 7 14:51 sessions

[zimbra@mail someuser]$ cd tmp/

[zimbra@mail tmp]$ ls -lr
drwxrwxrw- 2 zimbra nobody 0 Jan 7 14:58 full-20090107.195815.073

it's possible you're getting this error because the backup script is attempting to do something filesystem based that the smb share does not support.

Wondered about that... working from here:

Ajcody-Backup-Restore-Issues - Zimbra :: Wiki

he uses nfs as his example. Haven't tried that yet, it will be my next step - but I did try the --zip and --zipStore options as well, no seeming change.

thanks

yeah i've done backups to nfs fine, but thats because nfs supports unix permissions

you can probably test it like cd to /mnt/smbbackup/ and creat a file, then try to do a chown or a chmod on it i bet you get a permission denied error.
