RE: IFS limits

The number of the objects can be vastly offset by the size of the objects.
750k IFS objects saved in almost 3.5 hours. However many of those are in the GB size, like Domino email files with no limits on email sizes or mailbox size enforced. (business decision)
SSD and VTL

Yep, we had that before as well.
Looks like based on Robs input the limits have been upped.
What I don't know if the IFS has become any more efficient for backup and recovery in the past 10 years.

Do you mean 1 million IFS files in a single directory? We have a user with over 1 million IFS files (*AUTL, no private authority) with no issues.

Boy have I got an IFS story for you.
Found out the hard way on IFS limits several years back with a customer.
Customer was generating 1,000,000 documents per month. Yep, per month.
We discovered ownership limit was about 1,000,000 documents.
Started getting user issues and things blowing up.
Ended up creating a directory each week I believe and a new user profile to go with it.
Now talk about painful management of objects.
250,000 is probably not bad, but probably time to open a new directory if possible.
Either way with that many objects IFS backup time is probably slow.
And eventually you may see object ownership issues unless ownership limits have been bumped up.
Many customers that I have worked with have migrated to using NFS and SAN these days which means you treat it like IFS, but it's not.
And object ownership issues go away and you have to back up the SAN or NAS of course. But that disk is much, much cheaper.
Hope this helps
