Dan Sorry to bore everyone with the log post, most everyone probably already knows this stuff, I'm as you know a relative neophyte with PC paraphenalia so not bored yet and I love hearing about how people handle configs and backing up. If you are really dead set on having a realtime, constant backup/mirror of your current system, I don't need or want real-time mirroring. I want to schedule a once a day copy. Maybe mirror is incorrect terminology. I know technically there is a difference. Basically I want what Backup Exec does, which I also am currently using, except I don't want the qic file. I want an exact replica of C: at another location which is updated once a day. And it has to be bootable. I'm also using DI in addition to Backup Exec so you and I are not far apart as we now stand. Except I use DI in w98 DOS Mode instead of a DOS partition. I'm not too good in DOS. I agree about concentrating on trading and not administration of my system. I just need to get the system to a point I'm happy with. I want to get a backup NT a la Spots in gear in addition to the DI files and I want one other bootable backup to C; that gets updated daily in addition to the daily offline Backup Exec files. This may be too complex a plan..this is an issue I'm grapling with and I'm glad you accented it. I just need to fine the right balance of data/os/hardware security and KISS. Thats a tuffie for me since I lack alot of previous experience. Glad to hear I'm concurrent with the solutions your currently using though.. I just need to be careful about not getting carried away. Please sing out if you think I am. But don't worry, I'm not getting involved with real-time mirroring . Clarence

Permit a quick, but stupid question. You said you have DI and PM. Why do you need PM if you have DI? Thanks, PW.

It seems to me that unless your needs are very elaborate and high level (24/7 total fault tolerance and redundancy) then one would be best served by KISS (keep it simple stupid) If you are really dead set on having a realtime, constant backup/mirror of your current system, why not just buy another disk and enable mirroring (RAID 1) at the system level? It is very effective and operates at the system level not relying on separate software to run. Granted it is not as effective in scheduling and file selection, but it works and nothing offers as good of protection against a drive going down. The data is written simultaneously to both drives. Agreed. Of equal importance to drive failure is user failure..ie install a driver and NT goes belly up. That is one reason we are looking for a 'delayed mirroring' implementation. If the mirror is scheduled then one may be able to avoid the write of a bad file/configuration to the mirror. Something like the seven second delay the networks use..gives them time to use bleeps. I agree with maintaining a simple system. The concept of maintaining a 'delayed mirror' of the C drive is simple. The question is/can the implementation be simple? A scheduled DI would work although a directly bootable drive is preferable. Zeuspaul
