Hello (running debian squeeze),
I use a perl script which creates incremental/hardlinked backups of my samba shares, tar-bz2'ing each file individually (tar is for preserving directory perms for easier recovering).
These snapshots are also shared for the users to be able to go back in time fetching modified/deleted files.
I would like to replace this schema with rsnapsot (rsync based) on a compressed filesystem, but my shares use ACL (posix, setfacl), mapped by samba to the windows clients.
I tried fusecompress and zfs-on-fuse, but they did not work with acl (at least not with setfacl).
I read somewhere that posix acls are obsolete, so zfs does not support it, supporting windows and nfsv4 acls instead (http://compgroups.net/comp.unix.sola...x-style/220004
). Can these replace posix acls for the samba mapping on a linux/fuse zfs?
Is there a way to have ACLs for the samba clients, without posix acls support on the server filesystem?
Or is there another compressed filesystem (not read-only) for linux (debian) which supports the "same" acl mapped by samba?
