Backup/restore

[ian]

Hello,

Backup/restore problem wit release 1.2.2

I have restored a configuration backup file ( from an eBox server release 1.2.2 ) on a brand new server from scratch with eBox release 1.2.2 and all the configuration settings are correct restored but the acces controls on the shares are not restored the access control is empty.

In the previous release the restore works correct.

Is there a solution for this problem ?

Thanks ,
Ian

Do you mean access control in File sharing -> shares -> access control?

[darklink]

I can confirm that this is a problem, we have the same one.
Once restored the config doesn't contain any information about share permissions.

This information seems to dissapear in the file /var/lib/ebox/conf/samba.bak as soon as /etc/init.d/ebox samba restart is run

[javi]

I'm looking into it...

Hello Javi,


Yes it is in: File sharing -> shares -> access control.
This results that users connected by a windows Xp workstation does not have access to the shared files on the server, the client even does not see the share anymore in the file browser.

As i said problem does not exist in release 1.0, the configuration is correct afther a restore of a configuration file on a new installed server.

eBos is a fantastic application, the only problem is that the developpers must take more care of backup/restore utilities in the application and be sure that here is no problem with upgrading to new releases. This will be result in a real reliable system.



Best regards,
Ian

Ok guys, bug confirmed. The error is that the restore process does not have into account that it has to restore the users module before the samba module.

Until we upload a new package fixing this, you can easily workaround this issue running:

Code: [Select]

sudo /usr/share/ebox/ebox-restore-backup  --module samba /var/lib/ebox/conf/backups/<your_back_up>.tar

The above command will restore the samba module from the backup file it takes as an argument. As users and groups haven been already restored you will get back your access control configuration.

Thanks for reporting this!

Nice one, thanks!

 

Better and quicker support than most commercial softwares!

hello Javi,

I have tried on my test server, but the problem is still there.

Afther executing your proposed command, the access control lists on the shares are still empty .

However the file smb.conf is ok now , the share definitions are now back in the smb.conf file and the users on the client workstations have access to there files.

So there is still the problem of seeing the access control lists in the eBox administrator screens.

Maybe this extra info helps to solve the problem.
Thans ,

Hi,
 we have a fix in the backup process, that I think it may solve your issue. This is not package yet, but if you need it right now you can patch your installation manually.

To do so:
1) Grab the new version of the Backup.pm file at -> http://trac.ebox-platform.com/export/15054/trunk/client/ebox/src/EBox/Backup.pm
2) Use it to replace the previous version at /usr/share/perl5/Ebox/Backup.pm 
  (For example: cp -bf /tmp/Backup.pm /usr/share/perl5/EBox/Backup.pm )
3) Restart ebox webserver with this command:
/etc/init.d/ebox restart

Thanks,

Should i replace this file on the server where i will backup the configuration, and make a new backup of the configuration and then restore the backup file on the new server ?

Regards an thanks again,
Ian

Ian, this seems another different bug. You get this when you click in 'Save changes' after the restore?.

[ian]

Javi,


This error appears afther i have copyed the File on the eBox server and reboot the server, Samba wont start again and give the error.

P.s. i have copyed the file to the eBox server, where i will made a new backup of the configuration so that this configuration can be restored on a new eBox server build from scratch.

I did not tryed to copy the backup.pm file on the new installed server buid from scratch, and then restore the configuration.

So the problem is, afther copy the new backup.pm on the server and perform a reboot of the server Samba is not restarted, and give the errors.

Best regards,
Ian

[javi]

Can you please do this?

Code: [Select]

sudo /etc/init.d/ebox samba stop
sudo testparm
sudo /etc/init.d/samba  start

And check the logs in /var/log/samba/*
