Hi all, I have a system running on btrfs which is backed up to two (one local USB and one through SSH) external drives (also using btrfs) using send/receive (with the help of btrbk). For each backup a snapshot is created and transferred to the external drives. After some time, the snapshot on the origin is removed but kept on the two backups. Now my problem is, that the SSH-drive has not received any snapshots for some time such that there is no snapshot any more which is on the origin AND the SSH-drive. I would like to prevent transferring a full snapshot over the network and am now trying to work around it. Here the current situation (S? for a Snapshot): Origin: S2 S3 USB: S1 S2 SSH: S1 Transferring S3 to USB is no problem as S2 is on both btrfs drives. But how can I transfer S3 to SSH? I tried to transfer... 1. S3 from Origin to SSH -> does not work as there is no common snapshot. 2. S2 from USB to SSH -> did not work. 3. S1 from USB to Origin (such that there is a common snapshot with SSH) -> did not work. Is it correct that 1. would work if a common snapshot is present on Origin and SSH? Is it expected that 2. and 3. do not work? Is there some other way to achieve it?
