A review of the top three blog posts of 2010 based on Google Analytics: Fun with ZFS send and receive for powerful filesystem commands, Stopping SSH Brute Force attacks with PF for server security, and Pulling data from Warcraft Armory with Groovy which gained attention from the Groovy community including Project Manager Guillaume Laforge.

Two Python scripts for managing ZFS snapshots. The first script creates timestamped snapshots of all filesystems in a zpool. The second script automatically removes snapshots older than 30 days by parsing the timestamp in snapshot names, useful for automated backup cleanup.

An exploration of ZFS send and receive commands for filesystem management and backup. Covers taking snapshots, outputting to files, combining with gzip compression and OpenSSL encryption for secure storage, using zfs receive to restore filesystems, and copying filesystems securely over SSH between systems.
