We have a single HP Windows 2003 (standard) server, running exchange (which is also nearly upto capacity) with a Ultra 320 SCSI card, implemented in a RAID 5 arrangement. It has a dual Intel 3.4GHz processor, and we have 4096 Mb RAM. The storage is 558Gb and of that we currently use 449Gb.
Our problem is that we have a HP Ultrium SCSI tape drive which requires more than 1 tape, which is now taking over a day to backup.
My question is what can we do to improve the speed of backing up this data. We have tried an external USB drive, but again this is taking too long. Is there something qhicker that we can implement, as we would like a backup to take place when the server is not being used, between say 18.00 and 8.00 the following morning - that gives us a 14 hour window.
Not sure about firewire or even USB 3 (our current test is using usb 2). Does anyone have any suggestions?
I know that 500Gb is not that much these days, so what is everyone else using?
