I was just asked the following question.

"Someone left the company, they deleted stuff, we don't know what was deleted, can you tell us? Oh and we don't know when it was deleted"

I was thinking back in 7-mode days, I could use snapdiff and compare the daily snapshots and find out what files went missing. Is there a way to do this with cluster mode snapdiff? Does a script exist that allows you to see what files are missing between snapshots?

Thanks in advance

I have just tried my old script (written for ONTAP 9.4) and it still seems to work fine with 9.14.1 😉 feel free to use it as inspiration

#

you still need the old SnapDiff API enabled though (there's a hidden command which enables SnapDiff V2, which you can get via PVR)

oh wait I see it's even properly documented now here and in the KB, so no need for a PVR anymore I think?

v2 is supported again after a short hiatus. The KB has the version list. The cmd in the KB and an appropriate LIF should be all you need from the ONTAP side.

thanks, I will look at this, I was using an rsync command but that requires a metadata walk. Thanks.

Yeah, I was deep in the middle of that as I run Rubrik and heavily use SnapDiff 😉

I am not a great python guy (perl is my thing 😉 ). Which module do I need to import? I did netapp-ontap, but that doesn't seem to be the right one.

sorry I can't help you much with perl myself 😉
I mean all you need is an XMLRPC library basically, in Python there's the "NaServer" module which is a thin wrapper around XMLRPC but you can definitely do it without any NetApp module(s)

do you know the name, is it NaServer? pip couldn't find that.

#

ah you mean how the collection is called? hmm I don't remember and I can't check right now as I'm at home... "netapp"? "ontap"? 🤔

no worries, I am googling. I installed the netapp-ontap module, but still getting an error:
ModuleNotFoundError: No module named 'NaServer'
