BetterBSD fully supports persistent L2ARC, meaning the cache index survives system reboots, eliminating the costly "warm-up" period.
Manually managing snapshots is inefficient and error-prone. Implement a programmatic lifecycle using tools natively supported or easily installed on BetterBSD (such as zxfer or sanoid ). A standard enterprise retention matrix looks like this: Every 15 minutes, kept for 24 hours. Daily: Taken at midnight, kept for 30 days. Monthly: Taken on the 1st, kept for 1 year.

FreeBSD has been the reference operating system for ZFS since Sun Microsystems open-sourced the project under the CDDL license. While Linux eventually gained ZFS via ZoL (ZFS on Linux), FreeBSD remains the most stable, performant, and "native" environment for advanced ZFS features.
