We found out about the drivers as well. The backup was taking up to two hours for a full dump of the stores. After updating the drives, we went down to 20 minutes or so.

It depends on other factors as well, the number and sizes of your tracking logs, the number of transaction logs on the server, are you indexing your message stores I'm currently backing up 164 Gbytes of data, that's a public folder store, three message stores in one storage group, tracking logs, transaction logs, indexes, etc. on one LTO-1 tape. Be advised, you may need to update the drivers on the PERC card and the SCSI card connecting the LTO tape unit in order to get decent performance out of it. The default Win2K drivers for the SCSI cards have a bug in them.

Subject: Backup onto LTO and compression question. This might be somewhat of a vague question. We current have a DellPowervault LTO 110T backup tape drive on our primary Exchange Server. It will back up 100 Gig non-compressed or 200 Gig compressed. Does anyone know the maximum size an Exchange DB can be if you use compression on the tape? I'm not sure how well the Exchange DB will compress.
