Mount a samba share using smbmount and then configure Back In Time to save snapshots into this share. Taking a snapshot don’t work, only some directories are created.
After some investigation: using a windows share it works, using a samba is doesn’t work.
Samba provide some extensions to the protocol to support uid/gid and permissions.
I mounted the share using smbmount (‘sudo smbmount’) and I create a directory: the user/group of the new directory are root/root and the permissions are user:rwx and group/other:rx only. Then creating a sub-directory will fail since I don(t have the rights.
To void problems the only solution I found is to mount the share using “-o nosuids,noperms” arguments (not uid/gid and no permissions). This way the application seems to works. The only problem is that snapshots are no longer read-only. Starting from version 0.9.24, user/group and permissions are stored in a special file so restoring them should be OK.
