-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, Sorry for this general question, but I'd like to hear your opinion on this subject, but I'd like to set up a really working backup solution for my PDC, currently it uses NFS, so there are lots of issues: No ACLs, When NFS server goes down, everything fails. What method would you recommend for replicating folders, keeping existing ACLs (ability of manipulating that ACLs from Windows is not important) between Samba PDC-BDCs: - -Rsync+FAM based scripts or - -Distributed filesystems: -Coda -Intermezzo etc. Thank you for ANY answer.

A BDC is not a mirror of a PDC, for file shares, only for the logon database. Clustered CIFS is *hard*, see recent discussions on samba-technical.

ACLs support in your Linux kernel 2. File systems formatted correctly 3. To mount the file systems correctly in /etc/fstab 4. Samba to be compiled and linked with the acls-devel libraries Here is an entry from my fstab file for example; /dev/hda6 /export reiserfs acl,user_xattr 1 2 I run SuSE SLES8, 8.2 and 9.0 with ACLs support without any problems. The relication of ACLs from a Windows server to a Samba server requires use of the correct Windows tools and does present limitations. You can do this only when logged onto the Windows server/client as the Domain Administrator and you must have Domain Administrator rights under Samba.
