Brad,--
I'd like to confirm something you said.
First, when saving an IFS object, the entire directory is locked until
the save is complete.
So if an application was trying to access that same directory, (but
not necessarily the same object), that app would probably fail because
of a lock.
Secondly, if an app has an IFS object "in use" then the save tries to
save that directory and object, only that "locked" object will be
skipped, but the rest of the directory would be saved.
Is this correct?
I have issues with both, I am trying to improve the save, but also
trying to guarantee that the save will not cause an app to fail.
Paul

We are talking about the majority of the data, and what's taking so
long, are the IFS objects. Not really any data in QSYS.LIB.
I only mention this because there seems to be a little confusion, and
I've experienced in the past when they're saving an IFS object, that
entire directory is locked until it's done. And locked down hard. :)

I don't see much difference between VSS and IBM i's Save While Active...providers.
Except that SWA has been available since at least 1997 or

The problem is too many shops don't bother to use it.

Yes, comes up in recovery mode the first bootup, subsequent
bootups are normal.
Second is what are you doing with those servers? Are these
hosting
Oracle or MSSQL Databases or are they file and print servers? Orname
are they just AD members that are used for remote desktop for example.
100GB database servers, print servers, file servers, web servers,
you
it. Everything in windows these days have volume shadow copy

IBM i really needs something like Windows volume shadow copy
service so you can achieve 100% up time during backups.
This is the only reason why I see AS400 shops are down
periodically, had the database been hosted on one of a windows box
we would have much
uptime.large

There is a large difference between a transaction oriented
system and a system hosting many flat (or 'stream') files.
