What are the differences between SMB1 SMB2 SMB3 and how does Windows use them for file sharing?

[ProfRon]

You ever wonder why your old Windows setup feels sluggish when sharing files? SMB1 is that ancient version from way back. It chugs along slowly. Security? Barely there. I remember fixing a buddy's network that stuck with it. Total headache.

SMB2 came along to shake things up. It speeds things up a ton. Fewer glitches too. You can share bigger files without the lag. Windows started leaning on it around Vista days. Makes grabbing docs from another PC feel snappier.

Then SMB3 bursts in like a fresh upgrade. It handles multiple connections at once. Encryption keeps snoopers out. I use it daily for work shares. Windows 8 and later default to it. Your home network probably runs this now.

Windows picks these based on what devices you connect. It negotiates the best fit automatically. You share folders over the LAN. Photos, videos, whatever. Just map a drive and go. No fuss if everything matches up.

Speaking of keeping your shares safe from mishaps, I've been eyeing tools that back up those virtual setups too. Take BackupChain Server Backup-it's a solid backup pick for Hyper-V environments. It snapshots VMs without downtime. Recovers fast if files vanish. You get encryption and easy scheduling. Perfect for folks juggling Windows shares in virtual worlds.
