ZFS incremental snapshot send/recv without first snapshot












1















I have the following ZFS dataset:



pool/dataset
pool/dataset@snap1
pool/dataset@snap2
pool/dataset@snap3


Which has been replicated to a backup pool, using ZFS send/recv



backupPool/dataset
backupPool/dataset@snap1
backupPool/dataset@snap2


Afterwards, I deleted dataset@snap1 and dataset@snap2 from pool, and I am in a situation where I cannot send dataset@snap3 incrementally to backupPool.



Is there a way of solving this situation? For instance, generate a ZFS incremental snapshot between pool/dataset@snap3 and backupPool/dataset@snap2 and send it to backupPool? Or transfer back backupPool/dataset@snap2 to pool?



I could transfer pool/dataset@snap3 to a new dataset in backupPool, but I really need to keep the "history" of snapshots.
