Yeah, I'd second that... if the server has a PERC4 in it as opposed to the newer RAID cards it's got to be a 7th or 8th generation Dell, and has either 0 or 1 USB2 port available. If I remember correctly the Perc4/DC has two external SCSI 320 ports, so you could plug in an external device and do backups via those ports. If you want to stick with a removeable drive you could always get a network-attached drive (Buffalo has a few GigE NAS devices) and even that would be faster than USB1...

Many servers do not, and you may be using it in 1.0 compatibility mode, which sounds about right based on your backup times.

Based on your replies, I started some testing. My math is correct, there is something in this particular I/O stream that is really slowing down the backup. Anybody know what the I/O speed of a Raid-5 array on a DELL PERC 4e/DC is suppose to be? From: Jim Majorowicz [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 16, 2008 10:28 AM To: NT System Admin Issues Subject: Backup Miracle I think I’ve been tasked with making something near impossible happen, so I’m going to start by asking the question here then start my google-fu. My boss has just asked for a backup solution that will do the following: Complete a full backup of SBS 2003 server. There is currently nearly 300 GB of data on this server. Wants Exchange included (Currently about 30 GB in size) Wants a system state Wants it verified. Must be complete in 10 Hours! The current backup system is taking about 24 hours to do this not including the verify, and I think there may be an I/O problem as it is NTBACKUP with BackupAssist v.4.0.16 backing up to a USB 2.0 drive. Unless my math is off, this backup should only take about 5 hours, assuming the transfer occurs at about 20 Mbps. Unfortunately there is some sort of bottleneck that is throttling this back to about 4. What am I missing that would help me fix this problem? ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~
