Everywhere I build now, I use Snapshots on file shares.

No, fuck you, you can't have that 20% of space. its mine.

off you go.
for example, dumping computers from WSUS:
Code:
sqlcmd -I -S np:\\.\pipe\MICROSOFT##WID\tsql\query -d SUSDB -Q "SELECT * from PUBLIC_VIEWS.vComputerTarget" -o "computers.csv" -s"," -w 20000]
craft your joins accordingly and away you go, just don't forget to wuauclt /reportnow every machine before query wsus

Again, I just tell people to estimate what they think they need, and then tell them that they need to buy double, no excuses, and 25% of that is space they'll never even know existed, but will save their arses a thousand times over.

The very first time some finance knob deletes "that one critical XLSX file" and needs it urgently restored, you point to a dozen read-only copies of it dating back hours/days/weeks, and they realise you weren't bullshitting.

Go CoW, or go home.

20% is my snapshots.
60% can be your data.
the remaining 20% is my fucking watermark for getting you to buy more storage.

What are you using to snapshot the shares?

ZFS/BTRFS/VSS - depends on the application/deployment.

We mount and share ours, but they're read only at the filesystem layer. Note even "root" is allowed to write to them.

Having them available to users removes a tonne of IT overhead. Although with that said, even after having been shown several times, there are still notable users who can't figure it out and need IT to restore files for them. But whatever, they're "high effort" users for a bunch of other reasons too, not just storage.

If an entire volume got wrecked, we'd restore the entire thing at the storage side (obviously *after* figuring out who/what wrecked it). So far it's just some user who accidentally deleted/changed something and needed to undo it, and typically a single file at a time.

I mean kinda? in a way. But its read-only. And its hidden by a guid

Code:
vssadmin list shadows /for=X:\
mklink /D c:\muhshadow \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy#\
So long as your defended from nubs purging VSS, you're fine.

Honestly... literally everything that elvis said.

I'm sure I wrote a post on how to deal with this shit years ago.

This is one thing Windows does well out of the box.

Until the malware deletes your shadow copies before it starts encrypting your files.
