RFS with TP has been available in UniData for 15-20 years too.
I understand your issues. I'm just saying you do have the ability in UniData to 
generate a consistent backup (physical and logical) using dbpause.

That's the rub isn't it?

We have a few thousand programs written over 30 years, and only a limited 
staff, and users always want more.
Users don't see the need to go back and *fix* code that's working, and/or are 
not willing to pay you to do it.

It's a cost-benefit issue.  For a site that doesn't *have* to be 24-7 but can 
be say 22-7, it's safer to shutdown, then backup.
You can't always control every piece of code someone has written.

If you have put transaction processing semantics in your code you will have 
logical consistency with dbpause. For RFS enabled systems, dbpause forces a 
checkpoint.

You get an extra benefit from stopud and startud in that your database will be 
consistent.
dbpause does not enforce consistency

Personally I would never suggest using dbpause to take a snapshot because of 
that issue.
You're never guarenteed that you have a clean consistent copy.

"dbpause" and "dbresume" allow any background processes (e.g. PHANTOM or WebDE 
(Redback)) to continue running. You do not have to have a restart procedure.
Additionally, as long as your backup methodology is brief - a SAN "snap" or a 
mirrored drive split - then anyone using Telnet, UniObjects or ODBC not even 
notice and can continue uninterrupted. Stopping UniData menas terminating those 
sessions

I'd look at what is blocking your dbpause - there is a Tech Tip in the U2
knowledgebase.- search on "dbpause" - you should find SFMA-13082.

Importance: High

U2users,

Will I get the same benefits by using stopud and startud as oppose to dbpause 
and dbresume? The reason for my question is that my server is running unidata 
7.2 but 50% of the time cannot resume and stays in dbpause state long after 
backup?

Regards,

Thomas Boadu | IS Systems Manager
