Hi! Given that the Omnia Turris router has an mSATA slot and two USB 3 connectors, I am pondering the feasibility for using it for backups of my home dir. I pondered checking out zbackup, attic or obnam for that, of which at least zbackup and obnam can do encrypted backups¹²³. Yet then I thought why not using btrfs send and receive directly? I found two answers: Client doesn´t encrypt. And even tough I think the Omnia will be pretty secure unless I configure a hole into it, I´d not feel that comfortable putting my whole home directory there unsecured. So my question is, would it be possible to have btrfs send/receive encrypted? So far I have only three ideas about it, the first two are similar: 1) Mount a dm-crypted loopback file formatted with BTRFS from the router on the client. Of course dm-crypt stuff need to happen on the client then. And I wonder whether I would loose most of the probably performance benefit of using btrfs send/receive this way. I could export the file with nfs for example. 2) Export a block device from the Omnia directly wie NBD or iSCSI or whatnot and use it with dm-crypt on the client. 3) Have all home directories crypted via ecryptfs and only send/receive the subvolumes with the ecryptfs files. Any other ideas? Something like this would also be nice to have to store on cloud storage. Something along the line to send a crypted btrfs send/receive stream. Ideally target could be a directory on some storage that doesn´t even need to be a BTRFS. But I bet that would be a lot of work to implement.
