I am just wondering if there is any point in bringing down CMOD when an online DB2 backup / backup of the cache file system is being performed. I believe at another vendor that was common practice and it did not take that long even with hundreds of millions of rows, 1000+ application groups.
I am working with around 650 AG's now and 140GB of data, and I am wondering if there is an absolute NEED to bring down CMOD during a backup.
Thanks
