Haven't done it with NDMP but for other multi-stream backups if you set checkpoints then you can resume any stream that fails and it will still be seen as part of the original backup. Another beauty of resume is it backs up from the point of last checkpoint before failure rather than restarting the entire stream.

I prefer doing backups this way as large NDMP streams fail and cause havoc when you have to restart it. You can then setup a 'catch all' policy that backs up All Local Drives, or all the mount points, but has exclusions for everything you've specified in the other policies. This way when someone adds something and doesn't inform you, it's still protected. -Rusty -----Original Message----- From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of oersted Sent: Tuesday, November 01, 2011 11:45 PM To: VERITAS-BU@MAILMAN.ENG.AUBURN.EDU Subject: [Veritas-bu] NDMP backups forget NDMP with Isilon.....there is much better method, which I have only done with NFS. Take your media server and hard mount UNC to each individual node. take the number of subdirectories in the root and divide by the number of nodes yes it might not be an even number, but you'll have slight imbalance..1 yes...you could script to check for subs in root and chop it up evenly and update backup selections Or, if you have tight controls where you work...anytime storage admin creates a new subdirectory in root, you are notified to rebalance backup selections. then set backup selections as follows For example: you have four nodes and 16 subs NEW_STREAM //unc-path-node1/ifs/directories 1-4 NEW_STREAM //unc-path-node2/ifs/directories 5-8 NEW_STREAM //unc-path-node3/ifs/directories 9-12 NEW_STREAM //unc-path-node4/ifs/directories 13-16 what this winds up doing is making the Isilon use its backplane (Infiniband) between nodes because that's what its meant for...the collective throughput of many connections to many nodes being hit all at once. 10GbE on media server really rips!! I've seen 500+ MB per seond +---------------------------------------------------------------------- |This was sent by sola...@cablespeed.com via Backup Central. |Forward SPAM to ab...@backupcentral.com. +---------------------------------------------------------------------- _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu Athena(r), Created for the Cause(tm) Making a Difference in the Fight Against Breast Cancer --------------------------------- CONFIDENTIALITY NOTICE: This e-mail may contain privileged or confidential information and is for the sole use of the intended recipient(s).
