We have a similar configuration to the one mentioned below and we are
getting between 6 - 10Gig an hour.

Compaq Prolinea 4 x 400Mhz
1 Gig Ram
Dual Ethernet (one dedicated for backup)
RAID 5 for Storage Pools
DEC TL89 DLT library
ADSM 3

Client Compression OFF.

I've never found ADSM to be great on performance but in terms of
manageability and reliability it beats Backup Exec hands down.
Backup Exec is great for small shops with about ten to twenty servers, but
in terms of the Enterprise it's a long way behind.

We actually have Backup Exec installed on a number of servers already. It
has been the bain of my life!

At least when ADSM breaks down IBM I get good support. We have Seagate
Premium Support here.
I've had better technical support from Gardener's World.

        Funny you should ask. I've been working on that quite a bit
recently.

        IBM NetFinity 7000
        4x200MHz P2 CPU's
        1gig RAM
        dual 100mb Ethernet (one dedicated for backups)
        +25gig RAID 5 for disk storage pools
        3447 DLT Tape library with dual DLT drives
        NT 4.0, SP4
        ADSM 3
        Client compression on, TCP/IP tuning, etc.

        The best we can do with this machine is restoring 1.5gig/hr over the
        network.  The data we're backing up is lots of small (<1meg) files
that
        don't compress much.  (My understanding is that if you have huge
mega-files,
        ADSM does better.)

        We've got a requirement to restore 260gig overnight or better. ADSM
just
        isn't good enough.  An early test with BackupExec on a much lesser
machine
        gave 6 to 7gig/hr. (DSS3 12gig tape, 1 CPU, 200meg RAM)

        If this holds true on production quality hardware, we're dumping
ADSM.

        Hi ADSM-ers!
        Last week I posted a question about the performance of ADSM on a
Windows NT
        server with a 3575 library.
        I would like to rephrase my question in order to receive more
replies. ;-)
        I'm looking for performance figures for a Windows NT server. I found
a
        report called "ADSTAR Distributed Storage Manager (ADSM) for Windows
NT
        Version 3 Release 1 Performance Evaluation Report" but it's dated
October
        31, 1997. For this test a 2-way 166 Mhz. Pentium processor was used.
        Hardware and processors are much faster nowadays, so I'm curious
about
        performances from the field.
        I'm very interested in performance over 100 Mb. Ethernet or FDDI.
        Any reply is VERY much appreciated!
        Kindest regards,
        Eric van Loon
