LTO Autoloader, 1gb per min, local attached, and across dual gigabit network
DL380 G4's, Windows 2003 SP1, Backup Exec 9.1
not the best, but that was well over 18months ago I put that in

LTO2, 1.2GB per min SCSI locally attached Windows 2003 SP1 with Backup Exec 9.1. Drops down to half that when backing up the remote agents over the LAN.

On a Dell PowerEdge 6650 with fibre connected storage, but with SCSI connected SDLT autoloader about 2Gb/min. Would the type of data have an impact on the speed of backup, ie the back of a single large database be comparitively quicker than the same amount of data in seperate, little, files?

Never thought about comparing throughputs!
Good choice in topic David
No point in even mentioning our rates, 10x DLT7000 in a STK L700. Slow is not the word...
This thread should give me some numbers to compare against when the new LTO's turn up.

Yep..
Also going to ditch Galaxy CommVault and probably go Netbackup..
Our problem is we are govererned by some tight financial regs, so need to keep the data for a minimum of 6 Years, this means there is around 10tb of data weekly going into secure storage..
We use Multiple SDLT and LTO2 Loaders, but we are only seeing @30gb per hour, but we do encrypt all data too..

Netbackup seems better than Networker (Legato product) - but all back-up s/w is evil.....

David, is throughput your biggest issue?
We use Netbackup to dump its backup images to a DataDomain device, it seems to average about 45MB/s for multiple jobs/streams. You can then duplicate the images onto tape and vault them with in our case slowww DLT's...

if you dump to disk first, do you then have to restore a backup file from the tape to disk and then restore the required file from that backup file, or does it deal with staging the backup files, and make restores easier??

Big plus is when people request a recently backed up file - no faffin' around trying to get a tape loaded back into the jukebox.

Most of our restores are normally from months ago, shadow copy on the data servers has helped though
Shame it costs £50 to retrieve a tape

Finally moved to our Server team so thought i'd come back to this thread.
Backup Exec 10d on DL380 G4's using MSL500's to SAN attached storage is giving 300-400mb per minute depending on which of our backup servers I look at. A 150gb job is taking about 6 hours.

80 - 90MB per second to LTO2
This is from a clarion SAN going directly to tape. With TIvoli Storage Manager
They are large SQL databases
