Hi everyone,
I manage 100+ SQL servers and some of them contain over 120 – 800 GB + databases. I googled for backup script that backs up database depending on the size and strips the .bak file to multiple files. So far no luck. The closest one I got to is this script. Is there a way I can backup smaller databases in one .bak file and 60 + GB databases to multiple .bak (stripped) files dynamically in the same backup script? This way I can standardize it across all the servers. Thanks in advance or your help.

CLOSE c_bakup
DEALLOCATE c_bakup

Please don't double post.
I inlcuded a better script for handling this
in your original post that does not include any cursors or loops.
P.S. if you search online for a way to do something in SQL and you find a solution that inlcudes a cursor or loop - I'd suggest that you keep searching...
