Yes, definite sarcasm, but practical sarcasm because not embracing the right tool for the job "just because" could make one appear to be a luddite.
Even a Linux partition might be a better answer if they want the data to be in the same Chassis. However NFS would still be in order most likely.
We fought with the IFS for years and now recommend that any large volume IFS storage of small files goes to NAS or SAN because of the backup performance and object security issues imposed by IBM i.
Smaller volume users can probably stick with IFS successfully.
Maybe with iASP you can back it up as a blob, but nobody has confirmed this for me.
Had a customer once who was creating a new directory each month and a new user profile to own the objects because of an OS error they were getting capturing lots of docs to the IFS. I think the threshold was ~ 1 million IFS objects owned by a profile.
With NFS and NAS/SAN that painful PC file management issue goes away completely.
Anyway...

subject: RE: Large volume file move
I know that Richard is coming off as highly sarcastic but I too have to
wonder why the big push to move this stuff to IBM i. We've done file
serving from IBM i. Normally Windows beats IBM i in file serving hands
down. Even on older hardware you could be using the same drives and all
but stick in an IPCS card in there and load Windows on it and it would
smoke file serving from the predecessors of IBM i.
IBM i has touted newer versions have caught up some but they still have a
way to go.
General policy here is that IBM i is not to be used as a file server
unless there's a really compelling reason to do so, such as CPYTOIMPF type
stuff.

Actually ignore save/restore since you're on Windows already.
Here's a tongue-in-cheek use case for moving docs to the IFS:
"I want to move my image documents to my central IBMi system which will
cost me more and cause my backups to slow down because I'm not comfortable
with Windows."
Personally I think this is a misplaced exercise since you already have a
reliable Windows solution. (Unless you are having server hardware issues
and don't have a network person.)
Or if you're a Windows-hater, move to Linux and then you can be a
Linux-hater too.
Either way you'll have cheaper storage and an OS which is meant to manage
small files.
More importantly....Do you currently back up the image files ? I hope
so......

We'll have a chance to test this with the POWER9 hardware before the
actual migration. That should shake out any ownership issues.
How could I do a restore/save, I don't know of common format?

I would expect to have object ownership issues when you move 20 million
files owned by the same profile. Unless that's been fixed recently for the
IFS.
Probably need to do a test perhaps. Perhaps multiple threads copying as
well if you can break it down to a list of files. (perhaps list to a DB
first.)
Also how do you know files don't get corrupted during copy. May need some
sort of data comparison if those files are important to stay intact.
Save/restore to/from tape perhaps and then file comparison by hashing or
reading bytes.
Or initial move to NAS/SAN as Rob mentioned.
Rsync also comes to mind.
Or.....leave them alone and back up your Windows server. IFS is not
efficient with lots of small files.
