This means that the dataset on the receiving system is protected using the same user key that is in use on the sending side. The idea here is to send raw encrypted and compressed data and receive it exactly as is on a backup system. This feature also adds the ability to do raw, encrypted sends and receives. Provides the ability to encrypt, decrypt, and authenticate protected datasets. Native data and metadata encryption for zfs OpenZFS introduces a -v option to zfs send which reports per-second information on how much data has been sent, how long it has taken, and how much data remains to be sent.Īrbitrary Snapshot Arguments to zfs snapshot illumos

OpenZFS adds a -v option to the zpool list command which shows detailed sizing information about the vdevs in the pool: It is also used for a -n option for zfs destroy which can instantly calculate the amount of space that would be reclaimed by a specific zfs destroy command. This new accounting information is used to provide a -n (dry-run) option for zfs send which can instantly calculate the amount of send stream data a specific zfs send command would generate. This feature enhances OpenZFS's internal space accounting information. Size Estimates for zfs send and zfs destroy OpenZFS has a per-pool comment property which can be set with the zpool set command and can be read even if the pool is not imported, so it is accessible even if pool import fails. Listed in chronological order (oldest first). While the end result is a generally more friendly user interface, getting the desired behavior often required modifications to the core of ZFS. These are improvements to the command line interface.
