Description Martin Haller 2009-12-14 07:10:34 UTC
Hi all,

firstly I would like to thank You, for this great SW. 

I have found a bug (maybe it is just not implemented feature). I would like to backup my Windows Server 2008 R2 to samba share with Windows Server Backup, but I am getting error:

"The version does not support this version of file format"

The backup job actually starts and create some files on a share, but then it throws this error and ends.

I have tested it on two PCs:
a) Gentoo x64, samba 3.4.3-r1, anonymous share, writable for everyone
==================
[global]                      

 workgroup = WORKGROUP
 netbios name = Martin
 server string = Samba Server
 log file = /var/log/samba/log.%m
 max log size = 50
 map to guest = nobody
 security = share
 encrypt passwords = yes
 unix charset = UTF-8
 socket option = TCP_NODELAY IPTOS_LOWDELAY
 wins suppport = no
 name resolv order = lmhost wins host bcast
 printcap name = /etc/printcap
 load printers = no

[share]
   comment = Martin
   path = /home/martin/temp2
   public = yes
   writable = yes
   force user = martin
   force group = users



b) Debian squeeze, samba 3.4.3-1, act as a domain member:
==================
My config is:
[global]
security = ads
password server = servername.domainname.tld
encrypt passwords = true
workgroup = DOMAINNAME
realm = DOMAINNAME.TLD
netbios name = backup
#idmap backend = ad
idmap uid = 10000-20000
idmap gid = 10000-20000
winbind enum users = yes
winbind enum groups = yes
winbind use default domain = Yes
log level = 2
profile acls = yes
nt acl support = yes


[share]
        path = /mnt/backup/server/current/writable
        browseable = yes
        read only = no
        inherit acls = yes
        inherit permissions = yes
        create mask = 700
        directory mask = 700
        admin users = DOMAINNAME\backupad, DOMAINNAME\administrator

I have found a solution for this problem. The solution and problem is discussed at technet http://social.technet.microsoft.com/Forums/en-US/windowsbackup/thread/13bb79e9-c970-4805-88cb-2000b3348070 .

You just need to add "strict allocate = yes" option to your Samba configuration.
