I have 1 DAT40 backup drive. I have 1 full backup on monday on serv 1, 1 full backup of server1 (Tuesday) , and differential badkup on wednesday, tuesday and friday.. Unfortunately I`m now experiencing that the full backup tape on server2 is getting full. I`m therefore going to plan a new backup strategy, I`d like to hear what suggestions others have to give me on what the strategy should be. serv 2 is an exchange server.

Is that data you are backing up on server 2 only the exchange database or are you also backing up something else? If you can't get your full backups onto 1 tape anymore, i'd try to separate the data to back up into categories. If your server 2 is an exchange server it also makes sense not to have any other data on it. Of course you don't need to backup the programs installed, because if you need to restore the server you will install the software again anyway. The programs don't change anyway, so if you do need a backup, you only need to do that (preferably by hand) if you change anything there.

The full backup of Server 2 is backing up the whole server, not only the exchange data, while the differential backup is on one tape, with data from both server 1 and 2. This does not however exceed the tape limit.
I have been told/read that when backing up Exchange it could be a good Idea to backup the Installation file in Program files --> EXchange (or whatever the Map is named) I thought this was strange, becaus as you said. If I have to restore The server, I would have to installe the software anyway. What you`re saying, is that I should only backup Exchange data, and others critical data like. ie. sql data etc. but not  the software  (or C: Systemdisk) at all?

Well you can backup your programs, but you don't need to do that regularly. I'd only do that once, by hand (not scheduled), and I'd only keep the programs on that backup. If you change something with your programs you can do another backup of them.

And, yes I'd only backup Exchange data, the exchange Transaction logs (are usefull if you need to rebuild a mailbox, these logs should be on a different drive than the data), SQL Data and Dumps (here the same strategy should apply as with the exchange logs), and do backup the "Systemstate" which contains registry data, Active Directory data etc. You can probably see something like "systemstate" in your backup software (I know Veritas shows this, and also Arcserve has something like this).

Yes. I usuallly takes a backup of the systemstate. I see the logic of not taking a backup of installed programs, but One question if I take a backup of the registry(system state), wouldn`t , if i have to restore from backup, create conflicts, since the registry wil contain values from former installed programs etc....? What about systemfiles?

Normally you should be able to select what you want to restore. Things you would want to restore is Active Directory Data, user data, etc.
