Backup Windows to an OpenBSD server

[girarde]

I have an OpenBSD box which I have been backing up to 6TB hard drives for some time now, using dump/restore. Works nicely. The 6TB drives are formatted FFS.

I have a couple of Windows machines that could use some backup, also. The 6TB drives go in a sled that I would prefer not to move around, and in any case they're FFS and Windows won't see the partitions.

I have succeeded in sharing them with samba, smb.conf like this:

[global]
   workgroup = WORKGROUP
   server string = Samba Server
   server role = standalone server
   log file = /var/log/samba/smbd.%m
   max log size = 50
   dns proxy = no 
   map to guest = Bad User

[WIN1BAK]
   browseable = yes
   path = /backup/WIN1
   writable = yes
   guest ok = yes
   public = yes

[WIN2BAK]
   browseable = yes
   path = /backup/WIN2
   writable = yes
   guest ok = yes
   public = yes

Those directories are owned nobody:nobody, permission 777.

WIN1 and WIN2 see the shares, start backing up, (writing files) and eventually fail with error 0x80070032.

Has anybody solved this without adding a backup package, and if so which?

For physically attached NTFS filesystems, I have used ntfsclone(8), a utility included with sysutils/ntfs_3g.

Do you mean physically attached to the OpenBSD machine? The backups I want to take are of internal HDD over the wire.

Yes, I do. Typically SATA or USB-connected.

Which would require an additional disk (non-FFS).
