Periodically a customer will report to me that a client is generating savesets in 2GB chunks. That is, they get savesets like the following:<\/p>\n
Under much earlier versions of NetWorker, this was expected; these days, it really shouldn’t happen. (In fact, if it does happen, it should be considered a potential error condition.)<\/p>\n
The release notes for 7.4.5 suggest that if you’re currently experiencing chunking in the 7.4.x series, going to 7.4.5 may very well resolve the issue. However, if that doesn’t do the trick for you, the other way of doing it is to switch from nsrauth<\/em> to oldauth<\/em> authentication on the backup server for the client exhibiting the problem.<\/p>\n To do this, you need to fire up nsradmin against the client process on the server and adjust the NSRLA<\/em> record. Here’s an example server output\/session, using a NetWorker backup server of ‘tara’ as our example:<\/p>\n So, what we want to do is adjust the ‘auth methods’ for the client that is chunking data, and we want to switch it to using ‘oldauth’ instead. Assuming we have a client called ‘cyclops’ that is exhibiting this problem, and we want to only<\/em> adjust cyclops, we would run the command:<\/p>\n Once this has been done, it’s necessary to stop and restart the NetWorker services on the backup server for the changes to take effect.<\/p>\n So the obvious follow up questions and their answers are:<\/p>\n [Edit – 2009-10-27]<\/strong><\/p>\n If you’re on 7.5.1, then in order to avoid<\/em> chunking you need to be at least on 7.5.1.5 (that’s cumulative patch cluster 5 for 7.5.1.); if you’re one of those sites experiencing recovery problems from continuation\/chunked savesets, you are going to need 7.5.1.6. Alternatively, you’ll need LGTsc31925 for whatever platform\/release of 7.5.1 that you’re running.<\/p>\n","protected":false},"excerpt":{"rendered":" Periodically a customer will report to me that a client is generating savesets in 2GB chunks.
