Destroying A Replication Package; Target Replica Backups - Oracle ZFS Storage Appliance Administration Manual

Destroying a Replication Package

The project and shares within a package cannot be destroyed without destroying the entire
package. The entire package can be destroyed from the BUI by destroying the corresponding
project. A package can be destroyed from the CLI using the destroy command at the shares
replication sources node.
When a package is destroyed, subsequent replication updates from the corresponding action
will fail. To resume replication, the action will need to be recreated on the source to create a
new package on the target into which to receive a new copy of the data.

Target Replica Backups

You can back up target replica datasets (projects or shares) using the NDMP zfs backup type.
Replica backup is enabled on the appliance by applying the deferred update Support for NDMP
zfs-type Replica Backup. The replica backup feature chooses the most recent system-generated
snapshot to be backed up, unless you specify a user-generated (non .rr extension) snapshot. For
more information, see "Replica Backups" on page
Some older replication snapshots, those originally preserved for future incremental backups,
might not be needed and can be deleted. If the snapshot is held by NDMP, a confirmation is
displayed warning of the potential impact to ongoing or future NDMP backups.
The following sequence of events causes a replication failure and generates an alert.
For information about recovering from this error, see "Name collision" in
Failures" on page 545.
1. A replica snapshot is held by NDMP on the target appliance (for an ongoing backup or a
future incremental backup).
2. The corresponding snapshot on the source appliance is deleted or renamed.
3. A new snapshot is created on the source appliance with the same name as the replica
snapshot held on the target appliance.
4. A replication update is attempted.
