Re: [Networker] Slow Netware Backups

Hi Librado

Just going through my email history and noticed your post.  The best that
speed that I've managed to get is somewhere around 6mb/s on average by
doing what you suggested below.

I sending this on because of your last paragraph

i.e.
Using this method requires diligence, because there might be a new
directory and forgot to advise the NW admin about it and won't be
included in the backups.

The way to work around this problem is to create two clients and a
directive
The first client backs up your sub directories

e.g.
user:Group/D-pi
user:Group/S-ei
user:Group/S-cpg

using the standard netware directive

The second client backs up the server using the ALL function in the
saveset.
You then make a serverside directive that says (note that the directive is
all in capitals)

<< "USER:GROUP/" >>
        +nullasm: D-PI
        +nullasm: S-EI
        +nullasm: S-CPG


Using this method, you will automatically pick up if someone adds new
directories.

Cheers!

[Networker] Slow Netware Backups






Hello All,
Is it on the design of Legato Networker that a backup of Netware server
using 'All' produces only 1 stream and very slow (800 KB/s to 1 MB/s)?
We have tried everything from NIC card settings to NetWare NLMs and the
latest NetWare client pack from Legato and still we cannot get a decent
throughput.
Finally, we tried the hard way, split the client's savesets, instead of
'All', we specified each directory under Vol1 which creates a total of
31 savesets.
With a client parallelism of 10, this gave us a throughput of 3 - 4
MB/s, on 2 DLT 7000 tape drives, but when we bump the parallelism to 15
so that we can use another tape drive, we have lots of 'connection time
out' and 'connection refused' errors.
Using this method requires diligence, because there might be a new
directory and forgot to advise the NW admin about it and won't be
included in the backups.

Any other possible solution/idea is greatly appreciated.

Environment: NW for AIX v6.1.3 (AIX O/S 4.3.3)
Client: NetWare v4.21 (NetWare v6)

thanks,
