How to transfer files over network preserving the xattrs?
Title.
The situation is basically this:
NFS works, it's very fast, keeps the xattrs but if used without Kerberos it's not secure. If used with Kerberos it works, but has a ticket that expires and forces me to reenter the credentials frequently in order to use it. If there was a way to use NFS with Kerberos and save the credentials NFS would be the perfect solution.
Samba works fine too, also keeps the xattrs but I had some troubles with filenames (mainly with some special characters, emoji, etc). Besides, as both my server and my clients run Linux I prefer to avoid it if I have the choice.
sshfs would be the natural choice, not as fast as NFS but it's pretty secure, I already use it in most of my network shares but I just can't find a way to make it preserve the files xattrs.
Do you guys have any suggestions or maybe any other options that I might use?
I appreciate your help, but notice that the article just tell some basics of xattrs usage (I already know how to use it), but has no reference of file transfering files, which is what I need.
I suspect you use them more extensively, than I. Mine are limited usually to the extended acls, which I then use getfacl to generate a dump of all the acls of the files and sub directories I am transferring or 7zipping, and include that file in the transfer or 7z bundle. Then use setfacl to apply all those permissions on the receiving end after everything has been copied or extracted.
