  1. FreeBSD Enterprise Storage Polish BSD User Group Internal Solutions 2020/02/11 Internal Solutions - Filesystems ● UFS - classic/mature/traditional small memory footprint UNIX filesytem. ○ UFS with Soft Updates (SU) allows Snapshots and dump(8) / restore(8) features. ○ UFS with Journaled Soft Updates (SU+J) with ultra fast fsck(8) process. ● ZFS - modern pooled UNIX storage. ○ Stable ZFS - based on FreeBSD Base System ZFS implementaiton. ○ Latest ZFS - based on ZoL/ZoF OpenZFS repository (use FreeBSD Ports). ○ Differences - http://open-zfs.org/wiki/Feature_/lags - detailed information. ● FAT / EXT2 - FreeBSD maintains BSD licensed FAT/EXT2 filesystem implementations.
