samba - Sep 2014 - backup script problem with samba 4.0.10

Hi dear list members

It's about 10 months that we have setup our samba 4.0.10 and using it as
the only domain controller and LDAP server (please note that our server's
hardware crashed 10 months ago and we did restore a bit old backups and
rejoin all computers to the domain).

To backup the samba database, I stop samba service at 2:00 AM every night
and backup using samba_backup script and re-run samba4 service with the
help of crontab. It could always create "samba4_private" file but
"sysvol"
and "etc" files were not created in some days! (both "etc"
and "sysvol"
files are created once in every 3 or 4 days)

Please note that, despite we get these errors, the "samba4_private"
file is
created each time I run samba_backup! but I don't know whether it is
corrupt or not.

Is it normal? I'm afraid it makes bigger problems in future!

Sncerely

The backup script shipped with the sources is really basic at the moment
(we really need something better :-)). But it should work everytime. If
not all archives are created, then you should try to debug what fails.

You can take out all >/dev/null 2>&1, and other things that suppress
messages and also run your cronjob with "bash -x samba_backup >
/tmp/log.txt 2>&1", to get all the output logged temporary.


But the script is able to hotbackup the databases. You don't need to
stop samba for it. But if you don't mind stopping samba anyway, why not
simply "tar --xattrs ...." your whole /usr/local/samba/. Then you have
everything. Important is just that you include the extended attributes.
So make sure, you use a tar version, that supports it.
