Hi guys,
We're having problems restoring some windows servers (W2K)... The
servers in question had some disk problems and are being rebuilt, so the
Windows admins are restoring the C: drive.

You are at which firmware on IBM LTO2 FC ?
We had last year big problems with firmware 38D0 , until we switched to

You can see that problem if you use tapeutil and skip to EOD and see how
long it takes.
Should be some minutes, was with our firmware one hour and more.
Just a guess.

Hi guys,
We're having problems restoring some windows servers (W2K)...
The servers in question had some disk problems and are being rebuilt, so
the Windows admins are restoring the C: drive. It is an 8GB drive and less
than 50% used, so only 4GB to restore. It has taken several days to
restore.

We are running adsm 3.7.0 on os/390. The client level is for nt servers

Sometimes a backup session will run long and keep going to 10am but that is
not always the case. Over the last week our restores are running very slow

Netware uses A LOT of small files, the Netware filesystem is not fast enough
to build the filestructure etc.
That's most of the times the performan

The slow restores I have on some of my NT servers...do I shrug and say NT ?
And the Unix's ?
