RE: NT & AS/400 backups

RE:     NT & AS/400 backups

In case you haven't seen this. It was in this month's Midrange Systems.
(See below I included article)
Here's the link  http://www.midrangesystems.com/issueframe.html
(Goto "Recent Issue" link)

I guess the AS/400 Kicks B.  when it comes to backing up NT.

"AS/400 SAV command and the Windows NT Backup program Ntbackup.exe"
"AS/400 SAV achieved 32 GB/hr while NT Backup achieved 4 GB/hr;"

IPCS Outperforms Stand-Alone NT

By Larry Greenemeier
Monday, October 19, 1998

While the AS/400 Integrated PC Server (IPCS) has already seen
considerable success in the area of server consolidation, one recent study
indicates the IPCS actually outperforms stand-alone Microsoft Windows NT
servers in the areas of file serving, print serving and tape backup, according
to IBM.

Using NetBench 5.01, developed by Ziff-Davis Benchmark Operation
(ZDBO), file-serving performances were compared between NT on the
IPCS and NT running on a non-IBM stand-alone PC server. The results
indicate a greater throughput capacity on the IPCS as the number of PC
users increases and creates a higher workload.

Using its ServerBench measurement, ZDBO discovered NT on the IPCS
delivers a slightly better throughput than stand-alone NT. The IPCS’s higher
throughput was consistently better than stand-alone NT, regardless of the
number of PC clients. ServerBench is an application serving performance
test that produces three different types of loads on the server -- processor,
disk and network intensive.

For the tape backup comparison, ZDBO studied the performance of the
AS/400 SAV command and the Windows NT Backup program
(Ntbackup.exe). When using AS/400 SAV, the NT IPCS shares DASD
with the AS/400, and any NT drives appear as objects to the AS/400.

ZDBO reports the following results: on the IBM 3590 high performance
(half-inch) tape subsystem, AS/400 SAV achieved 32 GB/hr while NT
Backup achieved 4 GB/hr; on the 3570 Tape Cassette Subsystem, AS/400
SAV achieved 11 GB/hr while NT Backup achieved 4 GB/hr.

ZDBO also reports that AS/400 SAV outperformed NT Backup on the
IBM 6385 13G quarter-inch Cartridge Tape Unit (CTU) 7.5 GB/hr to 3
GB/hr, respectively. Performance on both the IBM 6380 2.5 GB
quarter-inch CTU and 6390 7 GB 8 mm CTU was the same for both
AS/400 SAV and NT Backup.

Hello all,
Can someone point me toward the appropriate manuals or references?  I
have two AS/400s (V4R2 & V4R1) and an NT server (v4.0) on my LAN.  
What's the easiest way to get the NT server backed up to the AS/400? 
Are there any special considerations or procedures necessary to get the
NT data copied to the AS/400 tape unit?
Are there any restrictions on the kind of NT files, registry, etc that
can be included in the backup?
Can the AS/400 job scheduler control the backup function instead of the
NT server?
Lots of questions, so few answers.  Please be aware that I am an old
400'er (??) but new to the network environment.  Any help is
appreciated.

Thanks
Wayne
