This is exactly what we do as well. In my experience, it'd take a pretty
catastrophic failure to need these backups. I've had servers fail in the past
where the replica and server can be rebuilt using file backups and the other
replicas of the partitions. While I still wouldn't go without backing up NDS,
it's going to be a rare case that you need these, I believe, moreso than a
regular file backup.

In our case, we've got 3 servers that hold replicas of the root
partition. Then there's about 20 remote sites each holding a master
replica of their particular OU partition. Since NDS backups in TSM are
always a full backup anyway, it only makes sense to do NDS backups on
one node that holds a replica of root.
Unless anyone's got ideas I haven't thought of, anything more would
just be a waste of time.

While we are on the topic,
What is the best strategy for backing up NDS?
We have district sites with tape libraries and remote sites with
Netware clients that will either backup directly to the district TSM
server, or to a local tsm server with disk only and the copypool is on
the district server.
What's the best NDS strategy for a remote site? Maybe NDS backup of the
remote site weekly and let replication catch it up if a restore is
necessary?
I'm not really a Netware guy so any real-life stuff is appreciated.

TSMers,
TSM server 5.2.2 on AIX 5.2.2
TSM cliient NetWare 6.5
We were setting up a few new NetWare NDS replica servers (xSeries 345)
and tried NDS incremental backup. I noticed that;
1. 'dsmc i NDS:' will backup all the objects again and again as if
there is no true incremental backup of it. Documentation says about
'domain' option for ENTIRE NDS bacckup. So, do I have no choice, but
backing up the entire objects every night?
2. NDS backup was taking too long. Changed dsm.opt parameters; tcpw
64;
txnb=25600 and it helped a little bit. Any other suggestion on tunning
parameter for NetWare client backup?
Thanks a lot for your help!!
