Note: For any high-availability solution involving the transition and synchronization of data between two nodes, there is some risk of limited data-loss at the moment of failure. This potential loss is mitigated by caching and synchronization options made available by the underlying system in use, or added by the vendor. SoftNAS' implementation of ZFS is no exception to this general rule. ZFS offers inherent options to either prevent data loss or improve performance with increased risk. If using the default settings upon creation of your pools and volumes, SoftNAS' implementation balances the concerns of data loss and performance. If data retention is your primary concern, we recommend changing the Sync mode setting when creating your pools to 'always'. For more information about sync mode settings and the options available, see Working with Storage Pools.

Note: When selecting storage for replication, remember that for throughput to be as consistent and reliable as possible, a like to like storage configuration is optimal. Replicating data from a high performance EBS storage volume to a lesser performance object storage volume, for example, can create bottlenecks that can lead to potential data loss.
