I am missing companies like Sun/IBM/ATT “Brilliant but Complex” technologies you should know about: They are dying for “too good” File Systems: BTRFS: ZFS alternative, easier learning curve, good snapshots XFS: Enterprise performance, simpler than ZFS F2FS: For SSD-optimized setups Networking: BGP routing: If you ever need multi-homed connections
WireGuard: Modern VPN, much simpler than OpenVPN/IPSec
Cloudflare Tunnels: Bypass NAT/firewall issues easily
Database/Storage: PostgreSQL: Like the "ZFS of databases" - complex but bulletproof

using zfs send/receive, by leveraging snapshot pruning transfer only some directories of a zpool/dataset 1. Create initial snapshot 1
zfs snapshot pool/dataset@001
2. Remove unwanted directories (not to be transferred) 1
rm -rf /pool/dataset/unwanted_dir1 /pool/dataset/unwanted_dir2
3. Create second snapshot (only includes wanted directories) 1
zfs snapshot pool/dataset@002
4. Send only the second snapshot, with compression (-c for compressed stream) 1
zfs send -c pool/dataset@002 | zfs receive -F pool2/dataset
5. Destroy snapshot @002 (cleanup) 1
zfs destroy pool/dataset@002
6. Rollback to the original full snapshot 1
zfs rollback -r pool/dataset@001
7. Destroy snapshot @001 (final cleanup) 1
zfs destroy pool/dataset@001
