>WINZip protects me in this critical area. So I just paid for it and its done. What do you do for backups in 24x7 environments? Kick everyone off?

I've never been involved with a 24x7 multi-user environment (23.9x7 yes).

But I have this comment: Lets say you don't kick everyone off. You have a process that changes 10 tables. One user begins this process. Another user starts the backup. The backup copies 4 of the tables before the (other user's) process and 6 of the tables after the (other user's) process. Now, is that backup any good? Is it a good set of data?

I have never had to worry about this because we make backups when users are not using the data, but I am wondering how you backup data when users are in the midst of making multi-table changes.
