[Networker] Ideal for two RFEs for NDMP backups
2007-12-14 10:08:16
In my NetWorker 7.4 environment, I have a need for two features with
regard to NDMP 3 backups. I use NDMP to back up five Mirapiont message
stores. These are not NAS devices, but they do use NDMP for backups.
The server that hosts the email account I am using to send this
message is one of those Mirapoint servers.
First off, since I am using NDMP to back up exclusively email (I do
not use NDMP to back up any OS configuration files), we have a lot of
spam sitting on our servers despite throwing our best effort at spam
reduction. What I am wondering is if those of you who use NDMP to back
up NAS devices can tell me something about how your NDMP clients con
be configured. What I want to know is if you have the option to do
selective backups (where you can than recover individual folders or
files on your NAS device) and put in an NSR directive of some sort to
skip certain types of directories. I want to skip backing up the junk
mail and trash can for every user's account. Does your NDMP allow for
skip directives.
Secondly, on my NetWorker 7.4 server (its a Sun T2000 with Solaris
10), I notice that all the NetWorker related processes appear to run
on the same processor. My T2000 has 32 cores. When the indexing
processes for my NDMP backups begin, one of the processors always
drops down to the low teens in CPU idle time and when this happens,
responsiveness from the rest of NetWorker slows to a crawl even though
TOP shows hardly any system usage overall. So what I would like to do
is spread those nsrndmp processes out across the other 31 cores and
hopefully, it will allow the rest of NSR to run better. Is this
possible? If so, how? If its not possible, I am definitely going to
put in an RFE with EMC for it, although I won't hold my breath waiting
for them to respond.
