What solutions should I be looking at to allow an incremental backup via rsync over nfs4 to allow files to be encrypted on the backup host?
I have zero control over the backup host's software so the encryption would obviously have to be done on the client side. I want incremental backup to still work (though it can be whole files, I don't want partial file copying) because of low bandwidth availability.
Seems strange neither NFS or RSYNC have this ability built in after all these years unless I am missing something.
I found rsyncrypto but it doesn't look updated for a few years now and not as transparent of a layer as I hoped.
Thanks for this explanation. Would
/mnt/encrypted-home
be "virtual" any not taking any actual physical space, or for every file on/home
would there be space taken up locally, permanently for the encrypted file? I always use whole files anyway, I don't trust partial and it is not really beneficial with many small files. But does this mean to get the true filesize to compare to the remote it would have to encrypt locally each backup? – ck_ – 2014-08-17T00:35:33.487
