[Samba] Samba AD DC backup - again

[Stanislav N. aka pztrn via samba]

Hey list.

I've searched all over last year conversations and it is (kinda) still
unclear about backups.

samba_backup script assumes that samba4 was installed from source, not
from repository.

https://github.com/thctlo/samba4/tree/master/backup-script is too
overfunctional for simple backup script. Really, I know how to write
shell scripts, but sometimes have headaches reading them ☺

The question is: is it enough to copy /var/lib/samba directory (with
samba turned off), which contains:

# ls /var/lib/samba/       
account_policy.tdb  ntp_signd  private registry.tdb  share_info.
tdb  sysvol  winbindd_cache.tdb  winbindd_privileged  wins.ldb

And /etc/samba && /etc/krb5.conf, or it should do something else?

Hai,

I dont think its over functional, it includes everything you need for a good AD DC backup.

This is about the minimal you should backup for an AD DC.
If you want to backup samba when turned off. You need at least:
/etc/samba
/var/lib/samba
/var/cache/samba
/etc/krb*

Check if sysvol is included in you backup and i also suggest an extra ACL backup of sysvol.

!! Dont copy the /var/lib/samba when samba is running, you will get corrupted [l-t]db files !!

Read: https://wiki.samba.org/index.php/Back_up_and_Restoring_a_Samba_AD_DC

But the script is a "set and forget" and does all of above.
Im using it over a year now, so can you explain what the problem is with the backup script.

And i agree, its a "hard" to read script, so why not ..
Just dont read it, get it, set it and enjoy it.
If it does not work, report it on the list and we can try to help out.


Greetz,

Louis

The wiki is based around the default used when Samba is compiled from
a tarball. Distros put the Samba binaries etc into a lot of different
places, you just need to work out where.
Running 'samba -b' should help ;-)

Thanks for this hint!

[L.P.H. van Belle via samba]

If you run : smbd -b | grep ": /"

You see something like this :

SBINDIR: /usr/sbin
BINDIR: /usr/bin
CONFIGFILE: /etc/samba/smb.conf
LOGFILEBASE: /var/log/samba
LMHOSTSFILE: /etc/samba/lmhosts
LIBDIR: /usr/lib/x86_64-linux-gnu
MODULESDIR: /usr/lib/x86_64-linux-gnu/samba
LOCKDIR: /var/run/samba
STATEDIR: /var/lib/samba
CACHEDIR: /var/cache/samba
PIDDIR: /var/run/samba
SMB_PASSWD_FILE: /etc/samba/smbpasswd
PRIVATE_DIR: /var/lib/samba/private
CTDB_SOCKET: /var/run/ctdb/ctdbd.socket

And your welkom.

Greetz,

Louis
