Although BEs created with bectl(8) or sysutils/beadm appear in zfs list -t snapshot you should use the bectl activate command instead of zfs rollback .

In addition, this feature allows a snapshot with clones to be deleted pending the removal of the last clone by using the zfs destroy-d command.

Take a look at this Jim Salter - Mar 10, 2020 7:05 pm UTC That is it!

Snapshots with ZFS are similar to snapshots with Linux LVM.

Each snapshot is mounted on demand in the .zfs/snapshot directory at … You can rename a snapshot by using the zfs rename command followed by the snapshot name. So I'm tinkering around with ZFS on linux and zrep. Snapshot names consist of the name of the filesystem, followed by an @ and the name of the snapshot. let’s perform a simple full and then an incremental replication. ‘zfs rollback default@aug28 gave me an error message about ‘dataset does not exist’.

Includes snapshots and rollbacks. When you take a ZFS snapshot you are creating a read only version of the data you “snapshot” that you can always access as it was in that specific moment.

Additionally, zfs send and zfs recv don't work alone because all their operations are based on ZFS snapshot streams that can be received to re-create a file system. Ask Question Asked 6 years ago.

# zfs snapshot pool/home/bob@yesterday Example 3 Creating and Destroying Multiple Snapshots The following command creates snapshots named yesterday of pool/home and all of its descendent file systems.

This is the utility that creates the @zfs-auto-snap_frequent, @zfs-auto-snap_hourly, @zfs-auto-snap_daily, @zfs-auto-snap_weekly, and @zfs-auto-snap_monthly snapshots if it is installed. This program is a posixly correct bourne shell script.

See man zfs, search for Native Properties and then referenced and/or used for more info on exactly what those fields mean for filesystems and for snapshots. Each snapshot has an associated user-reference count, which is initialized to zero.

Even though the world is changing, you have an image of what the world was like at the exact moment you took that photograph. ZFS snapshot replication.

Previously, I wrote about ZFS storage pools and filesystems, storage arrays, and storage locations within the arrays, and how you can do some cool stuff with them like quick drive replacements.However, the best part of ZFS, in my opinion, is its ability to perform snapshots. I store all of my movies, music, tv shows, etc. Snapshots can be created almost instantly and initially consume no additional disk space within the pool. We can list snapshots using the zfs list command and specifying the type as snapshot: zfs list -t snapshot.

When you take a snapshot of a given dataset (‘dataset’ is the ZFS term for a filesystem), ZFS just records the timestamp when the snapshot was made.

No data is copied and no extra storage is consumed.
