Hello Everyone,
I have built up a backup server on my local lan with a couple of 8tb drives mirrored together. My plan is to export shares from it in order to backup system files/folders. For this I am using rsync. Normally I do not have a problem on local backups on the same computer/server. However, I am failing to understand how to keep file permissions and ownership intact when rsyncing to the NFS share.
When I backup to the NFS share the file/folder owner is changed and the permissions are not preserved. This would be a real problem if I have to restore something like /etc as I would have to go thru and reset ownership and permissions on every file/folder. I assumed that rsync would preserve all this and thus restoring files back to the original computer/server it would have the correct permissions and ownership. I guess not the case. So, I am investigating on what I am doing wrong here. Its either a configuration issue in NFS / Rsync or I am just not understanding things correctly.
RNC2 = Backup server running NFS
exports file contains:TREX = My server connected to RNC2 via NFS
NFS mount info:All computers on the same network.
The file permissions and ownership basically are not preserved. I have a work around right now. I tar up the directory, Then transfer it via NFS to the backup server and there I can uncompress it with :
Id like to skip this step with tar and have the preserved permissions and ownership kept intact.
