I have an SBS 2003 environment along with a Adaptec SnapServer which is used for storing company shares and redirection of each users P: drive. I run tape backup's each night for the data, information store, etc. along with backup-to-disk as well. I know that SBS servers have a single point of failure because everything is integrated. I want to create some redundancy for now and eventually move away from the SBS server. I have a few questions before I begin planning this.
1.) If II need to rebuild the server from scratch (OS, Exchange, re-install BackupExec, etc.) is it possible to restore all the data from tape? I was told that Backup Exec keeps a library of all the backup's and if you lose the library your tapes are practically useless.
2.) Would an extra domain controller in the SBS domain be sufficient until I can purchase a mail server and then migrate them fully?
I was thinking of purchasing a server to act as a DC, then purchase a mail server. I would then set them up and dcpromo the SBS server off of the domain and rebuild the server to act as a DC2.
Any suggestions/comments/etc are greatly appreciated. Thanks.
